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 😉
