i am interested in this ip tabling video but i am stucked by this question, why are you adding first octed with second octed to get 192 and also why do you continue to add that first octed with third octed? please i am going for exam soon
I'm 83 and have long been interested in network technology and protocols. Your videos are the very best I've ever seen for educating a person on networking fundamentals and beyond. If I were going to sit for a CCNA, your training is the one I'd use to prepare for that exam. Thanks for all the intense effort you put in to prepare and present these videos. They are awesome. I plan to watch all of them and so far, I've made it through the first three, and now I'm on to video 4. Very, very good work. Thank you for your contributions to this old person who has a fervent desire to keep learning until he dies.
Hang in there, Tech is going places, I feel with things like nuralink around the corner your ability to be productive and learn will increase by at least 2-3 decades.
Started my networking career from your ccna videos in 2022, june and landed job in 2023 , i have completed one and half year in my organi ation and curre tly holding another offer letter of 11 lpa. Thanks imran
I'm recapitulating my networking studies after 3 years being a house/mummy wife, and your videos are so good and short enough that gives me a chance to watch while my son is sleeping. Thank you so much for your hard work :)
Some people don't make good teachers but you sir are one of the best! Your voice is very calm and your method of teaching is easy to understand. Thank you for another great lesson!

I have learned all these CCNA videos of this introduction to cisco network and I can say that they are really helpful and useful to have very solid basis to be able to go ahead. From these videos, I wrote 99 pages in a note book. I really appreciate what Imran did and now is really easier to learn about other videos about networking aspects. Thank you so much Imran :)
This is by far the greatest video with the best explanation etc!. Using all the detailed concepts with my concentration I'm a 100% sure I will be Cisco Certified in a few months, Thanks a ton for taking the immense effort in making the videos and uploading them on UA-cam, God Bless you and your team
I've never done anything to do with computers and information technology but, after watching your Day 1 to Day 3AM videos and listening to your explanations, man, I already see myself up there in the networking industry .
well i would like to say. you are the best teacher ever. i studied networking during my engineering but cudnt understand a word of that at that time i wish this video was available at that time thumbs up and keep uploading such informative videos
ahsanramz Thanks for your comments. Please subscribe to our channel to get updated of new videos, like our videos and share them on social media platforms!
Imran I just want to say that your videos are great and super easy to understand. I saw the error with the number of hosts for class A but then saw the comment on this video that you fixed it. I went over your videos two years ago and now I'm taking a program in the university and going over all these IPs etc. again and I'm still coming back to watch your explanations because it's amazing how you simplify things, and make everyone understand that. I wish you were my instructor in the university that would makes things easier, but keep going and I just want to thank you for all your hard work on these videos.
Rahul Bajpai Thank you so much for your time and effort! you courses are very well explained and simple, helped me a lot! would like to read on that book as well! undeadhunter@gmail.com
Watching these videos as a refresher before attempting the CCNA. Have never heard that hotel analogy for the IP addresses and I must say that I'll be using it from now on if I ever get asked that question! Makes things so much easier for people that may not know
NetworKing i have one doubt about ip classification. everybody saying the ip class ranges starting octect,like first octect of class C ip address should be 192.x.x.x. But why everybody using 192.168.x.x. Not using 192.1.1.1 or 192.2.1.1, or 192.2.2.3 like that. The class of an IP address is decided by a First OCTET.
suresh kumar Hi Suresh, You are absolutely right that the IP addresses are recognized by the first octet. however, the network part of an IP would always remain same. As you know 192.168.100 is the network part of the IP. Its like an address 28 George street that will remain same. The host part will change from 1- 225. This is like a house number. every one has a different house number, mine is 104 your would be 107.
Hi Imran...your videos are exceptionally awesome. Very well explained. Was just going through your day 3 IP Address video, there is a small correction. Valid IP's for class A is 16777214. Because 2 to the power of 24 is 16777216 that is 16777216-2 ,=16777214
Really iam vry happy with these videos sir this makes me to learn more deeply in networking. and ur laugh,pics at ipv4,ipv6 concepts makes us to boost our energy levels , further in depth to learn more about the concepts.

Excellent Explanation Sir, I was really confused In IP addressing before, But when I watched this video I got a clear idea about Ip addressing, Thank you very much explanation.
Imran i want to say a big thank you to you for sharing our knowledge with us. its indeed wonderful. you are a great teacher . im able to make my notes from your videos. You explain things that even a 5year old can understand. I wish i could subscribe 100time ... Thanks very much

Thank you very much for this videos.. Never thought it would be so easy to learn networking. .. I am little confused about the math u have done there. It will be helpful if you show me how to solve that math.. Thanx again...
Thank you so much for your fantastic videos! These videos are extremely helpful, they are clear and concise. My only regret is that I did not know about your videos 7 years ago, which would of made a massive difference and lead me to a better ICT career path.
i like your videor Sir i'm happy so to listen to your clear English as well as your knowledge im a network student from french speaking country your clear lessions will force me to learn more English language
OUTSTANDING!!👍. You guys do a great job of breaking it down. I have an interview in a few weeks and I feel that I'll know what is required. Thanks Again!
This is very good tutorial. Lot of critical topics of networking is explained here so easily, so that i can understand lot of important and critical topics of networking. Thank you so much Imran .

I have the same question 🙋♂️ valid IP address should start at 133.123.01 and end at 133.123.255.254…. What is the effect on the network? The network should not work ?
honestly i am relieve and well satisfy with this video i am new in the field, really needed someone to follow me up with the CCNA certification but thanks to this video is so helpful and simple to understand. i wish you could be my mentor. May God bless you with more wisdom
Imran Rafai Sir your tutorials help me alot to learn about the world of networking. As i want to start my career in networking i regularly start watching ur videos. Thanks

that's really amazing... your teaching method is really good and you explain it in a very easy way . It helps me alot in understanding IP address. thank you so much sir for making it easy to understand.
NetworKing Why evebody using the following range, As per the theory first octet is deciding the class.so why using the 192.168.x.x. and 172.16.x.x.. Any reason... 10.0.0.0 - 10.255.255.255 (Class A)172.16.00 - 172.31.255.255 (Class B)192.168.0.0 - 192.168.255.255 (Class C)
+suresh kumar Because these ranges are Private IP Ranges defined by IANA and are not routable on the Internet. Hence, these may be used by anyone in their private networks. Hope this helps.
Number of Hosts in class A comes 16,777,214 according to formula. I need to divided it to 8 to get 2,097,150. My question is why I need to do this? I didn't do it in class B and C. Could you please explain? Thank you
Tanvir Parvez Thanks for your comments. Class has indeed has 16 million IP address. The video has an error and we have corrected it with a label that comes up over that figure. You DONT have to divide it with 4. Please subscribe to our channel to get updated of new videos, like our videos and share them on social media platforms!
Hey man.. You are correct.. 😂😂😂 For just an instance I thought my calculator does not working properly.. And then saw your comment.. For no. Of hosts we use 2^24 - 2 and that is 16M.. Imrans's Slide has an error.. Thanks.. 👍
Just to make this a bit clearer: Class A 8 bits (1st octet) = network 24 bits (last 3 octets) = hosts Number of valid host IPs 2^24 - 2 = 16,777,214 Imran's slides are wrong at 22:00 Ogochukwu Igwe spotted this but I thought I'd expand on the detail
man it's 2017. I am watching this series you created and it's really really simple , very helpful and exciting. I would like to thank you sir for all the effort you put into it.
Suraj Nair Thanks for your comments. Please subscribe to our channel to get updated of new videos, like our videos and share them on social media platforms!
Thank you Imran for this well-explained video, i have a question regarding the Subnet Mask, you are saying based on class C for example its 255.255.255.1, a /24, and so on for Classes B and A, is this like fixed for the class as it goes always hand in hand with IP address being determined by the first octet?
Imran you are just awesome. I am getting all the thing in a sequential manner and i want to go more deep in this ocean of networking. Thank you so much for the video series.

Thanks for your comment. Please subscribe to our channel on UA-cam. And also give us a review on facebook: facebook.com/pg/NetworKingConsultant/reviews Everything that is inside the Demarcation Point (the place where ISP's responsibility ends) is the company administrators responsibility. ISP would assign 1 public IP to your gateway, but for everything inside the network either a DHCP server needs to be configured or a system of static IP would be needed. Please continue watching our series and it builds on your knowledge and setting up networks are all explained.
Mr KANNA, it depends if you're working in company as network administrator! You assigne private addresses but incase you need to go to the internet, your isp assigns you a public range of ip address if not and you use nat directly configured on your local network gateway HOPE I HELP OUT THANKS
I am a 2nd year btech student and although networking is not a subject for me right now but as a CS student networking is very important and your videos are too good and I really mean that your explanation is damn good 😊
Hi Imran, thank you very much for sharing your knowledge. Here I have a question. Workstation A has been assigned an IP address of 192.0.10.24/28. Workstation B has been assigned an IP address of 192.0.10.100/28. The two workstations are connected with a straight-through cable. Attempts to ping between the hosts are unsuccessful. What two things can be done to allow communications between the hosts? (Choose two) A. Replace the straight-through cable with a crossover cable. B. Change the subnet mask of the hosts to /25. C. Change the subnet mask of the hosts to /26. D. Change the address of Workstation A to 192.0.10.15. E. Change the address of Workstation B to 192.0.10.111. Answer: A B My concern- As the ip is of class C, hence total no of 1s=24, so subnet mask of the hosts to /24 not /25 as it is in the answers. Please advise.
ashish Jaiswal Thanks for your comments. Watch our subnetting video for your answer. Please subscribe to our channel, like our videos and share them on social media platforms!
Imram, seems to copy & paste the same messge to all people asking questions and yet not giving any answer. Why /25 in Class C address, u ask!? With CIDR you can specify the bits to decide how many host u need for thay network. in that /25 example, that means that u have 7 bits left to assing hosts. The subnetmask would be : 255.255.255.192
i have one doubt ..may be not directly related to this video but still i want know the solution....i want to access a local server which is running in my laptop ...from my mobile phone ..but i can do this by using my laptops ip address assigned by my router....i want give a domain name to this ip address....so i will enter a domain in my mobile browser and it will open up my server page.
+Ankit Yadav Thanks for watching. You need to change the hosts files on your phone! You can create an entry where you put your domain to be redirect to the the localhost ip address. Remember, this will be local to your device. So if you make host entry changes in your phone, only the phone will work as planned. If you want a more network wide change (home or office network), you might want to have a local DNS server and configure the domain name on that. So all devices on your local network will reach your laptop for that particular domain. Visit our website www.nwking.org to know more about our company and get updates on new videos.

I am going through these videos and saw your question. In your home network the private dynamic IP addresses is assigned by your home router within a fixed range. But in a corporate (large network) environment the DHCP server (or its role) does this job. You can also set up a static IP address (within the range that you are allowed to) for any devices on the network.
Only this class you explain very complicatedly... But others, I understand very well. And also about IP addresses, I have learned from another source before, so it was easier. I recommend you to make another video and easier one. Thanks for amazing videos and explanations.
The buzzing from the microphone is driving me up the walls...... hard to concentrate when I have something buzzing in my ear the whole time. im already starting to reach for my aspirins and im just in video #3.. (sigh)
man i seriously like the way you teach its very understandable u are the best i have been trying to look but u are one of the best teachers even you examples are related and good
loopback ip address is special ip address designated for software loopback interface of a machine. It is used for testing ip softwares without worrying about corrupted drivers or hardwares.
Let's say you send the message "Hello" to the loopback IP address (127.0.0.0). The message "Hello" will be sent directly to the machine you sent the message from. The address addresses your own machine, "looping" the data back to where it came from. Hope that helps
@Yesh Surve 127.0.0.0 is the network address and if you ping that IP from your machine it will give you "General failure." You can ping anything between 127.0.0.1 and 127.255.255.254.
Thank you so much for this and the easy explanation and test at the end. My company has agreed to take me and train me for their NOC departments. These videos will help my training go far more smoothly
127 series is reserved for loopback. Loop backs are used for testing a network stack and other lab usage. So if you ping any ip address starting from 127, your computer will always reply as long as your TCP/IP stack is working. Stay tuned. Subscribe to our channel, if you have not yet done so!

You will be my bestfriend for the next few weeks! Thanks for the videos! I took CCNA classes in 2015 but never made the exam, i'll attempt to do it in June with your help, with all this new stuff i think i wouldn't make it by my own! Thanks alot!
Imagine school was taught like this. Just videos you could get through at home and rewatch while taking notes by yourself then maybe like 1 or two days a week at school to go over stuff. Feel like I would've learned a lot more.
Hello Imran, the way you explain was so clear and elaborated.My assignments got an A.Thanks for giving us such a beautifully videos.Hope you continue this.
Hello Imran Sir. You have thought us Networking very nicely. You have cleared all the basic concept of Networking. Thank you so much sir. God bless you sir and I wish you a lot of sucess in your life.

NetworKing i have one doubt about ip classification. everybody saying the ip class ranges starting octect,like first octect of class C ip address should be 192.x.x.x. But why everybody using 192.168.x.x. Not using 192.1.1.1 or 192.2.1.1, or 192.2.2.3 like that. The class of an IP address is decided by a First OCTET.

Hello suresh, people use 192.168.X.X because it's the private range of the calsss C.

I have the same question 🙋♂️ valid IP address should start at 133.123.01 and end at 133.123.255.254…. What is the effect on the network? The network should not work ?
honestly i am relieve and well satisfy with this video i am new in the field, really needed someone to follow me up with the CCNA certification but thanks to this video is so helpful and simple to understand. i wish you could be my mentor. May God bless you with more wisdom

Day 5 Video Online. Watch it TODAY from our playlist: ua-cam.com/play/PLh94XVT4dq02frQRRZBHzvj2hwuhzSByN.html
NetworKing Why evebody using the following range, As per the theory first octet is deciding the class.so why using the 192.168.x.x. and 172.16.x.x.. Any reason... 10.0.0.0 - 10.255.255.255 (Class A)172.16.00 - 172.31.255.255 (Class B)192.168.0.0 - 192.168.255.255 (Class C)
+suresh kumar because its a well defined standardized range.....so everyone follow these ranges.....
+suresh kumar Because these ranges are Private IP Ranges defined by IANA and are not routable on the Internet. Hence, these may be used by anyone in their private networks. Hope this helps.
Yes.thanks
I have stated Yesterday and I like the way you teach. crisp and clear.......CHEERS! Thank you for such a beautiful series?
First, i really like your videos, very good Job, thanks for it..!
But the Microphone Interferences are horrible on Headphones :(
DragonSixZero seriously they should fix that.
I knew nothing about IT but these tutorials are eye opener, thanks Imran hoping to complete and take my exam in December

I have gone thru first three videos. I found them very helpful and informative. I am looking forward to completing your series.
Number of Hosts in class A comes 16,777,214 according to formula. I need to divided it to 8 to get 2,097,150.
My question is why I need to do this? I didn't do it in class B and C. Could you please explain?
Thank you
Tanvir Parvez Thanks for your comments. Class has indeed has 16 million IP address. The video has an error and we have corrected it with a label that comes up over that figure. You DONT have to divide it with 4. Please subscribe to our channel to get updated of new videos, like our videos and share them on social media platforms!
thanks for this . i had the same problem too now i understand
Hey man..
You are correct..
😂😂😂 For just an instance I thought my calculator does not working properly..
And then saw your comment..
For no. Of hosts we use 2^24 - 2 and that is 16M..
Imrans's Slide has an error..
Thanks..
👍
Again, simply smashing. I thank you and my mother thank you. Smile. You are simply amazing
For class A 100.228.111.225 number of valid ip is
- 2 = 16,777,214 valid IP addresses not 2,097,150
cool, I thought I was going crazy
Me too,
Ogochukwu Igwe I see
good
Just to make this a bit clearer: Class A
8 bits (1st octet) = network
24 bits (last 3 octets) = hosts
Number of valid host IPs
2^24 - 2 = 16,777,214
Imran's slides are wrong at 22:00
Ogochukwu Igwe spotted this but I thought I'd expand on the detail
man it's 2017. I am watching this series you created and it's really really simple , very helpful and exciting.
I would like to thank you sir for all the effort you put into it.
1:33 that guy is funny, just the same image appears, when ever I hear all those numbers in IP ADDRESS.😂
In My junior year of high school my math teacher taught everyone how to read binary. He was an awesome teacher and I learned a lot from him.
The test kept in the end was very helpful. Great Job!
Suraj Nair Thanks for your comments. Please subscribe to our channel to get updated of new videos, like our videos and share them on social media platforms!
This is the best explanation to IP addresses I have seen so far. Thanks a lot!
Thank you Imran for this well-explained video, i have a question regarding the Subnet Mask, you are saying based on class C for example its 255.255.255.1, a /24, and so on for Classes B and A, is this like fixed for the class as it goes always hand in hand with IP address being determined by the first octet?
Imran you are just awesome. I am getting all the thing in a sequential manner and i want to go more deep in this ocean of networking.
Thank you so much for the video series.

thanks a lot ! i'm really happy because now, i finish this day and i learned the Ip Address !
Powerful indeed
Oh my god....such a hardwork you did to explain the content....amazing....kuddoos
I have gone through 3 videos till now...very well explained
Who will be assigning this IP address to the PCs? will it be the ISPs or the administrator of the company?
Thanks for your comment. Please subscribe to our channel on UA-cam. And also give us a review on facebook: facebook.com/pg/NetworKingConsultant/reviews
Everything that is inside the Demarcation Point (the place where ISP's responsibility ends) is the company administrators responsibility. ISP would assign 1 public IP to your gateway, but for everything inside the network either a DHCP server needs to be configured or a system of static IP would be needed. Please continue watching our series and it builds on your knowledge and setting up networks are all explained.
Mr KANNA, it depends if you're working in company as network administrator! You assigne private addresses but incase you need to go to the internet, your isp assigns you a public range of ip address if not and you use nat directly configured on your local network gateway HOPE I HELP OUT
THANKS
I am a 2nd year btech student and although networking is not a subject for me right now but as a CS student networking is very important and your videos are too good and I really mean that your explanation is damn good 😊
Hi Imran, thank you very much for sharing your knowledge. Here I have a question.
Workstation A has been assigned an IP address of 192.0.10.24/28. Workstation B has been assigned an IP address of 192.0.10.100/28. The two workstations are connected with a straight-through cable. Attempts to ping between the hosts are unsuccessful. What two things can be done to allow communications between the hosts? (Choose two)
A. Replace the straight-through cable with a crossover cable.
B. Change the subnet mask of the hosts to /25.
C. Change the subnet mask of the hosts to /26.
D. Change the address of Workstation A to 192.0.10.15.
E. Change the address of Workstation B to 192.0.10.111.
Answer: A B
My concern- As the ip is of class C, hence total no of 1s=24, so subnet mask of the hosts to /24 not /25 as it is in the answers. Please advise.
ashish Jaiswal Thanks for your comments. Watch our subnetting video for your answer. Please subscribe to our channel, like our videos and share them on social media platforms!
Imram, seems to copy & paste the same messge to all people asking questions and yet not giving any answer.
Why /25 in Class C address, u ask!? With CIDR you can specify the bits to decide how many host u need for thay network.
in that /25 example, that means that u have 7 bits left to assing hosts. The subnetmask would be : 255.255.255.192
All your videos till now is very knowledgeable and easy to understand.
i have one doubt ..may be not directly related to this video but still i want know the solution....i want to access a local server which is running in my laptop ...from my mobile phone ..but i can do this by using my laptops ip address assigned by my router....i want give a domain name to this ip address....so i will enter a domain in my mobile browser and it will open up my server page.
+Ankit Yadav Thanks for watching.
You need to change the hosts files on your phone! You can create an entry where you put your domain to be redirect to the the localhost ip address. Remember, this will be local to your device. So if you make host entry changes in your phone, only the phone will work as planned. If you want a more network wide change (home or office network), you might want to have a local DNS server and configure the domain name on that. So all devices on your local network will reach your laptop for that particular domain.

Thanks Mr. Rafai !! You have cleared all concepts of IP Address in detail !! A Big thumbs up to this video, will surely recommend to all my colleagues ! :)
what if the first octet adds up to 127? Which class will it belong to?
+Sakshay Saha It doesn't belong to any class. It is reserved for loopback interface address.
thanks mr.imran.. i am start learning ccna through your videos..
whenever we connect to internet we need an ip adddress but who provides ip address?
+rahul kumar Thanks for watching. Public IP Address are automatically provided to you by your ISP. And organizations like IANA assigns IP address blocks to your ISP.

I am going through these videos and saw your question. In your home network the private dynamic IP addresses is assigned by your home router within a fixed range. But in a corporate (large network) environment the DHCP server (or its role) does this job. You can also set up a static IP address (within the range that you are allowed to) for any devices on the network.
U r the best teacher ever !!!
Thank u so much Sir !!
May Allah give u what u want ..
Thanks. Stay tuned for more!
add subtitles to ALL videoS SIR PLZ
Only this class you explain very complicatedly... But others, I understand very well.
And also about IP addresses, I have learned from another source before, so it was easier.
I recommend you to make another video and easier one.
Thanks for amazing videos and explanations.
The buzzing from the microphone is driving me up the walls...... hard to concentrate when I have something buzzing in my ear the whole time.
im already starting to reach for my aspirins and im just in video #3.. (sigh)
man i seriously like the way you teach its very understandable u are the best i have been trying to look but u are one of the best teachers even you examples are related and good
plz expiain loop back ip address
loopback ip address is special ip address designated for software loopback interface of a machine. It is used for testing ip softwares without worrying about corrupted drivers or hardwares.
A very common example is Localhost. 127.0.0.0
Let's say you send the message "Hello" to the loopback IP address (127.0.0.0). The message "Hello" will be sent directly to the machine you sent the message from. The address addresses your own machine, "looping" the data back to where it came from. Hope that helps
127.0.0.1 Localhost
@Yesh Surve 127.0.0.0 is the network address and if you ping that IP from your machine it will give you "General failure." You can ping anything between 127.0.0.1 and 127.255.255.254.
the more you talk the Indian you sound not that i don't appreciate the work you're doing here
thank you man
Great videos liked and subbed each one of them. By the way I love the enthusiasm you start your videos with :D
Thanks for your comments. Please subscribe to our channel, like our videos and share them on social media platforms!
I couldn't agree more to this but a very nice work NetworKing.. Thank you so much..
Thank you so much for this and the easy explanation and test at the end. My company has agreed to take me and train me for their NOC departments. These videos will help my training go far more smoothly
what is LOOKPACK ip address (127 series) and why particular 127 series are reserve for LOOKPACK ip address??????
127 series is reserved for loopback. Loop backs are used for testing a network stack and other lab usage. So if you ping any ip address starting from 127, your computer will always reply as long as your TCP/IP stack is working. Stay tuned. Subscribe to our channel, if you have not yet done so!

Imagine school was taught like this. Just videos you could get through at home and rewatch while taking notes by yourself then maybe like 1 or two days a week at school to go over stuff. Feel like I would've learned a lot more.
