Thanks Bill, I thought with ipv6 it was a sin to subnet on bit boundaries and not on nibble boundaries.
Hi Aaron, Not a sin but you're making more work for yourself if you subnet on other-than four-bit nibble boundaries. Each character in the hexadecimal printed version of the IPv6 address is 4 bits, aka 1 nibble. So subnetting on a nibble boundary means that each character in the address is either part of the network portion of the address or part of the host portion of the address, never both. Conveniently, IPv6 reverse DNS also delegates on the nibble boundary. Heck, I’m gonna do whatever it takes to NOT subnet on bits with my v6
deployment. Hopefully with v6, gone are the days of binary subnetting math.
Good plan. -Bill -- William Herrin ................ herrin () dirtside com bill () herrin us Dirtside Systems ......... Web: <http://www.dirtside.com/>
