IPv6 subnetting for dummies

IPv6 subnetting for dummies

Does anyone know any useful links to break down IPv6 subnetting without all the equations?  I get IPv4 subnetting fine, but all the explanations similar to microsoft's for IPv6 make my head go numb..


I know that for every bit you take for subnetting, you get 2^2 available subnets (2,4,8,16,etc.).  So in IPv4, if you want 4 subnets from 192.168.100.x/24, you get 192.168.100.x/27, with 6 available subnets (8-2) and a subnet mask of  And each network ID would be:

All increments of 32 since the last bit taken is in the 32 bit slot.

What I don't understand, is how you apply this same logic to IPv6 without all the equations.  There's got to be a simple way to do this.  Any good links, articles, books, or help in general would be appreciated.
