Duplicate Username. The username already exists in this or another Salesforce organization. Usernames must be unique across all Salesforce organizations. To resolve, use a different username (it doesn't need to match the user's email address).
Without subnet mask, we just by looking class or first octet, could identify network and host portion... Isn't it ? We know if first octet belong to class A, then Class A has 1 network portion and 3 host portion.
You will understand that in later chapters. There are several reasons why subnet masks are necessary. With classful addressing, you might end up wasting IP addresses. For eg, if you have a small network that fits into a Class C address space but you're assigned a Class B block, you would waste a significant number of IP addresses.
I have one doubt that 255.255.255.0 etc in dubnet is default na means it is notjing particular but only a exepted convention to select network in ip but if it so then what is need of sending it as by class it is already known maybe it is not really send t is only for understanding can anyone clear this
Understood that why there is need to send subnet see when in internet all the people are using net can default subnet masking is used but let's suppose in an organisation that are using limited IP's they can change the subnet default in order to define thei less IPS into different networks so I think now it is crystal clear that why default mask is 255 in case of Internet and it can be changed in the case of organisation for specific requirements
From wikipedia: Classless Inter-Domain Routing (CIDR /ˈsaɪdər, ˈsɪ-/) is a method for allocating IP addresses and for IP routing. The Internet Engineering Task Force introduced CIDR in 1993 to replace the previous classful network addressing architecture on the Internet. Its goal was to slow the growth of routing tables on routers across the Internet, and to help slow the rapid exhaustion of IPv4 addresses.[1][2]
I would just like to say one thing - huge respect for you.
Where is this BEST TEACHER hiding from our Sights..... AMAZING Way Of Explanation...
Bundle Of Thanks
Just amazing, I was pretty confused with subnet masking, now it's clear to me thanks to you😀
I love the way you simplify these concepts, thanks a lot.
Like this channel is too good to be free..likeee thanks for the intricate breakdown of concepts
Sir you are the Best tutor of the world😎😎😎
I agree. What an explanation
Amazing explanation ❤❤❤
Thanks a lot, i really understand after saw one time of your video
Thank you so much. you made subnetting more clear to me.
Thankyou for explaining so well Sir!
Class Ye🗣🗣🔥🔥💣💣
😂😂 oh please!
Thank you Neso academy
I didn't understand This lecture while others fully understood
Well done. Very amazing explanation
I love your teaching, fantastic
Respect to your effort.
great effort ❤

How is this comment even relevant to this video? Are you trying to communicate with someone else via this video??
thank you to making these video
Superb ❤❤
bless your soul
please upload transport, session, presentation, application layer
Thanks 👍
Omg so goood ..
I still don’t understand it😢
what don't you understand?
Pray God first
@@eliyassiyoum8393 don't waste his time
Still??
Rewatch it you will surely get it the second time of watching
Wow i clearly understood. Thanks sir.. i will subscribe and join group
can you please explain i didn't understood at all, what is the summary of this, what should we take from this

Same doubt

I'm studying this in Class 11 for my CTF.... Understood veryy well
Sir please make gate classes for electrical engineering
good video
If u have any complete gate course for ee i will buy let me know please

There is a mistake in number of possible networks in class C: Correct possible amount of networks in class C is 2,097,152.
2,097,150
Missing. 😅10.10.10.10
For Class C, 2 to the power of 21 is 2097152.
