IPv6 Subnetting - The easy way

In this video, I demonstrate how to do basic subnetting on the nibble (4 bits) boundary using a quick hack, no maths involved ;)

Nibble bit boundary subnetting gives clean increments, i.e. 0, 1, 2, 3, 4.........e, f and are easy to read. Reverse DNS in IPv6 also works on the nibble bit boundary.

Of course, there's a formula to get the subnet increments [2^16 – (L’%16)] 😩 where L' is the sub-prefix length, but trust me, there's no maths in this one :)

There are lots of handy IPv6 subnet calculators online, so don't try subnetting by hand past the Nibble boundary......oh, and don't use a spreadsheet for your IPv6 address plan, the address space is huge 😉

Hi Bashir, thanks I enjoyed the video. in IPv6 we can only omit the leading zeros.
I also have a question for you: We divided the hexademal digits by 4 equal parts because we needed 4 subnets, in case we need 5 or 7 or 9 subnets how do we do it?

The rules of representing ipv6 address says we should omit reading zeros not trailing zeros

This is a really great video. Thank you so much!

[TelloLetoao]

Its because we are allowed to omit leading zeros

Would you please try this one to explain FDBE:A661:24D4::/50 should be devided in 6 subnets

[famzmanjang]

Because the 8 comes first, we can't leave the zero's

I think this method only works with /16 /32 /48 /64 /80 /96 and so on...
