- On a TCP/IP network, why do we use both IP and MAC address?
In order to answer this question, we need to answer these two questions first. 1) What happens if we just use MAC address alone, and 2) what happens if we just use IP address alone?
MAC address tells us “who” you are which will never change, and the IP address tells us “where” you are, which can change. Both IP and MAC address makes sure the message is delivered to the right device on the right network. They work together perfectly in TCP/IP world.

Finally, a video that clearly explains the difference between the two. Good job man!!
Call him Sir, and you will learn more in life...

I've been in IT for almost 20 years and that was, hands down, the best video I've seen on explaining something so easily and in layman's terms. WOW.
@@jayexplains6010 you are advertising your video kkkkk
I swear
See? This guy knows what needs to be explained, and how to explain it. I'm currently studying for my A+ certification, and wanted to know the hard difference between the two. Now I know. Big thumbs up.
Some guy on youtube with a 3 minute video > my tutor
Every.single.course.at.university
Thank god some one finally explained this. I know what they are, how they are assigned, where they come from, where in the OSI layer they are, how to trouble shoot them, the list goes on. But I have trouble explaining why we need both, and no one can simply answer that question. It's always, Mac address is a physical address and IP address is a logical address blah blah blah.... thank you for making this video, now I can explain it too.
EXACTLY !!!!
if you are looking for a more simpler explanation i think you are in the wrong field lol, so simple to understand with this video, thank you
Thank you for your compliments!
Clear and Concise. No extra jargon. Easy to understand by anyone. Thank you.
Wow I can't believe I understood your videos more other than the ones posted here. Thankie.
THANK YOU.. I asked this question to every network guru I know, and no one answered it as clearly and adequately as you did.. THANK YOU
I've been watching a few videos about the difference and felt like I sort of got it but being told that ip addresses tell you WHERE you are but not WHO you are explained it perfectly for me, thank you.
Thank you, Professor! Now I understand MAC address = who I am and IP Address = where I am (postal address) Never ever ever have I seen such a succinct explanation. You're the best! :-)
2 months of CCNA7 couldnt explain what this video just did in 3 minutes. Thank you sir.
Perfect explanation. Mac address is Who you are, not where you are. Ip address is where you are, not who you are.
Many thanks!
From India, Hi sunny sir, your way of teching is very clear & deep... thank you for your fantastic video..kindly keep it ahead...god bless u dear
you are always to the point in less possible time.. at the same time you speak slow enough.. Keep adding more!!!!

So much better than a professor or a video lecture reading slides thank you sunny!
Oh, Mr. Sunny... this was so very helpful and brought it home for me. You have a knack of explaining things! Your visuals are also (always) so spot on! Thank you!
You are welcome and thanks a lot for your nice words.
One of the most brilliant easiest way to understand something through Mr. Sunny. Thanks my great Teacher
Thank you so much Sunny! I watched a number of videos. Your video helped me understand the difference between Public IP and MAC address better than any other video. You are talented.
Great to hear!
Best analogy ever seen, for IP and mac adddress. Thank u sunny sir. 🙏 Keep up the good work.
I love it when it pros use analogy's like this. makes it so simple for me.
I've been using your videos in reference to concepts I cover in books to get a different and often more visual understanding and they have helped loads! I am now a solid subscriber!!
Thank you very much! I appreciate .
Holy shit, been confused for weeks, one 3 min video and I suddenly understand it.
Million thanks for this helpful explanation, it helped me to deeply understand and my knowledge sharpened. I truly hope that I’ll pass this exam with a remarkable score!
So far the best explanation! Thank you very much for your contributions Sunny.
I love this guy and the way he explains, worth many likes !
1) What happens if we just use MAC address alone, and 2) what happens if we just use IP address alone?
MAC address tells us “who” you are which will never change, and the IP address tells us “where” you are, which can change. Both IP and MAC address makes sure the message is delivered to the right device on the right network. They work together perfectly in TCP/IP world.
Absolutely genius explanation. Thanks man.
Thank you Teacher Sunny.

We love you Sunny!
Agreed
Great videos Sunny! They are the most easy to understand, for me.
Great teacher...love you man
Thank you!
very nicely explained !!, can u please tell me why can't we use the mac address like a unique mail address(IP address) also? so that there wont be any IP address required
Great job man... First video that I understood clearly
Glad to hear it!
Thanks for your well explained
That is a nice summary there
Thank you for watching! I appreciate it!
Very good explanation, thank you sir.
You are welcome
Very Impactful! Thank you very much.
the advertised network can tell where you r . i agree. why cant we use ip address to tell who u r ? y use mac ?
Great explanation!
Thanks for the video!
perfectly explained. Thank you so much
Keep Update the Video please :))
I can understand your explanation easily
Many thanks. I will upload more videos. I appreciate your time for watching my videos.
Thanks a lot sir for such nice explanation :)
you are a good teacher..
Thanks a lot for saying that. I hope my own students think so too :)
Loved it!!!! Brilliant explanation
Thank you, for clearing my doubt.
You are welcome, Saksham.
@@sunnyclassroom24 hi, please you said ip address changes with network. so what of the phones that have double sim-cards, why do they have only one IP address combines & if you change one of those SIM cards what will happen?
Thank you sunny for the clear explanation
This explanation is good for theory but not for explaining to interviewer.We may need to explain with real scenario why mac is not enough to route packet to destination,.
Good explanation though.
Thank you for watching!
Your explanation is awesome! and informative. Please keep making more and more videos.
Thank you! Will do!
Loved this one, and the sponge Bob style song
Now I understand. Thank you. That was a very clear explanation.
Very clear! Thanks
You are welcome!
Great explanation, thank you.
Thank you for this great effort!
You are welcome!
great video. What would happen if we mannually enter a IP, MAC mapping with the correct IP but an incorrect mac? would the messages be rejected?
thank you sunny!
You are welcome!
Thank you.
You really helped me out!
the explanation that actually works
Again, very clear!
beautiful explanation awesome video
Glad you liked it
Very well explanation .. Thanks a lot
Nice video as always!
Thanks for the visit
Love from India❤
Any plans for a video on how to *change* a MAC address?
For example, I tried connecting a usb-lan-adapter (ASIX AX88179) in a linux virtual-machine (windows 10 host), yet when when I try ethtool it says the device doesn't support eeprom access.. yet it's the asix driver lists it as supporting eeprom/ethtool writing!
inspiring lesson
Thank you for clearing my doubt in such simple words.
You are welcome!
Fantastic video , very easy to understand. Thank you so much
Easy Explanation 💯🗣
Very helpful video.👍👍
Glad to hear that
Excellent explanation, please make videos on ethical hacking, may God bless you
Wowww the best video ever. Well explained thank you
very simple to understand Thanks
thank you Sunny
It put a smile on my face(:
Other than using ip address to identifying the network where host is located, can the ip address be used to identify the host too?
Now my doubt is clear thnks
I am glad it was useful.
thanku so much sir . The way you explain topic made me fan of you :p
keep upload the more vedios ..
Very clear. Cheers!
Thanks.
simple yet powerful
Is the same to differentiate virtual and physical
mac address?
What is the difference between a private IP address and a MAC address because it seems they are both needed on a LAN.
Thankyou very much
Thank you for so easy understanding explanation!
You are welcome!
Thank you
It should be sufficient to know where you are to communicate and exchange data, why would i need to know who you are and make use of an address hardcoded into your nic ? Especially when u consider ARP protocole that would learn mac addresses based on ips ?
very nice video, and really really helpful
simply Brilliant !!!
Amazing video Sunny!
Many thanks for your nice comment.
TQ FOR THE KNOWLEDGE SHARING
Thank you 👏
Mac address on android box start c42af and at tv screen start 00:28:13 and my tv provider said it should start 00:1a:79 can you explain me .
Great explanation! Thanks for the video :)
okay, I finally get it! Thank you
What I don't understand is why the MAC address is first in the frame. If IP is where you are and MAC is who you are, wouldn't you need to know where you are first?
impressive. I agree that MAC is useful and efficient for local communications. Imaging a couple of hosts which don't attach to ip, how can they communicate with each other? how can they identify themselves in a local area network?
MAC address would be enough if there are only a couple of hosts. That is exactly how local communications are designed.
can we change our mac in linux ?
Amazing content
Thank you for watching!
Nice points covered!!
thanks a lot for your positive comment!
