Short and sweet! One of the best subnetting explanation i've ever seen.

I agree with you 100%. This explanation is the best I've ever seen. This is why I'm downloading this video in case it gets deleted.

That "key" at 5:40 is A-mazing! Totally jaw-dropping. Just awesome! Thank you!

There's an even easier way to figure this out. Since the last stolen bit is in the 32 place value you automatically know the network will increment by 32. If the last stolen bit is in say the 4 place value then you know the network will increment by 4, if the last stolen bit is in the 16 the network will go up by 16 and so on and so forth. I absolutely agree with you though, this guy's GOLD!

The bit block's he is talking about is also called the magic number method

Great series of vids. Thank you so much! Am I right in thinking the range of the second of the two class A /9 subnets (@7:20) is 10.128.0.0 -> 10.255.255.255?

why does he just pick 3 bits

@TheTrthseeker 2 жыл бұрын

This is great, just one missing factor for a newbie to understand; why do we 'take 256' and I see whatever the chosen number we subtract 128 [I understand 128] but trying to follow this narrative. My thoughts; 1) I know 255 binary is what we have been learning is equal in decimal value or equivalent to the 8 1's binary octet? 2)128 X2 = 256? Is that the reason 3) use 256 because 2^9 [there are 9 ones now] and that equals 256 since there are 9 1's? The video says we take 256, but I don't know why that number as I am sure it is easy, but I want to get this?

Why do we subtract 2 from 16 to get 14 bits in class B

@claudiajackson2486 3 жыл бұрын

Do we always subtract the third octet in class b to get the subnet range?

how can 255 be in class A? i thought class is between 0 to 127, class b from 128-191 and class c from 192-255?

@nahom144 Жыл бұрын

never mind that's the subnet address not the network IP

@Yu-jr9uf 3 жыл бұрын

why we steal a bit in class A and 3 bits in class B?

@AnjilNiraula 2 жыл бұрын

it depends upon how many subnets you want to create. let's say you want to create 4 subnets from a given ip. then you would borrow 2 bits as the number of borrowed bits from host id is doubled to create the required subnet.
