IPv6 Network Address


ipv6-network-address

IPv6 Network Address corresponds to the first 64 bits of the 128 bits IPv6 address.Refer below:

0010000000000001.0000110110111000.0000100011110101. 0001000010100101.

0000000000000000.0000000000000000.0000000000000000.0000000000000000

The zeros in red are what the network address portion means… Let’s say:

0010  0000  0000  0001 : 0000  1101  1011  1000 : 0000  1000  1111  0101  :  0001  0000  1010  0101

These are those reds at the top that is grouped again into nibbles. I would take into consideration that you have a knowledge to conversion from binary to hexadecimal already! If not, refer to the tutorial. Let’s convert them by group:

0010  0000  0000  0001 : 0000  1101  1011  1000 : 0000  1000  1111  0101  :  0001  0000  1010  0101

2        0       0       1  :  0       13       11      8  :  0        8        15       5  :  1        0       10       5

We know that IPv6 is written in hex… And that it only covers a span from 0-9 and A-F :

0  1  2  3  4  5  6  7  8  9  A  B  C  D  E  F

So, the above statement becomes:

2001  :  0DB8  :  08F5  :  10A5        or         2001  :  DB8  :  8F5  :  10A5

Meaning, you can omit unused zeros in the beginning of the statement.

I put into instance that you understood everything,… So, before you go, I would like to test you…

Putting into instance that you are given a bits of 0001  0010  0011  0010 : 0101  0110  0111  1000 : 1001  1010  1011  1100 : 1101  1110  1111  0001, now give me the Network Address of my P.C. in IPv6… leave your answer as a comment below. thanks.
