Hi Tyler, Nibble boundaries offer two valuable characteristics in IPv6: First, it simplifies reverse DNS delegation since ip6.arpa is implemented on nibble boundaries. Second, it makes it easier to understand written IPv6 addresses and subnets, since the subnet boundary always occurs between written digits instead of causing those digits to change. I agree with David on the nibble boundary issue. I concede David's point that when arguing against a /16 I'm really arguing against a /19 because anyone reasonably justifying a /19 should see their netmask to expand to /16 to meet the nibble boundary requirement. To be clear: I think /19 is more than should be allocated based solely on the intentionally weak technical justifications we've selected. And I'm in favor of keeping the intentionally weak technical justifications for smaller allocations.
