Convert IPv4 into IPv6

I was going through 6to4 tunnel configs and thought I’d post some info on converting IPv4 address into IPv6 Address. This is pretty straight forward and its obviously involves HEX conversion.

Here, I will convert the address 192.168.25.234

First we divide each octet by 16 and write down the remainder, primary school maths! :)

192 ÷ 16 = 12 remainder 0
168 ÷ 16 = 10 remainder 8
25 ÷ 16 = 1 remainder 9
234 ÷ 16 = 14 remainder 10

We also know that HEX has the following Values

A = 10
B = 11
C = 12
D = 13
E = 14
F = 15

So we can write 192.168.25.234 into HEX like so… C0A8:19EA

Now we will change the HEX Address C0A8:19EA into regular IPv4

C0 = (12 x 16) + 0 = 192
A8 = (10 x 16) + 8 = 168
19 = (1 x 16) + 9 = 25
EA = (14 x 16) + 10 = 234

QED :)
