Lorenzo, I'm curious about the issues the host developer faces. It seems to me that there are three basic ways of configuring addresses: 1) SLAAC 2) DHCP IA_NA 3) Manual There is of course also DHCP IA_PD, but I'll leave that out for the moment as it is not directly relevant to IIDs. For DHCP IA_NA, the host should not care about the length of the IID. The host just configures the address as a whole. Not need to look at the prefix length. With manual configuration, again the host doesn't care. If is possible that manual configuration is done using IIDs. But combining an IID and a prefix is not magic. There is no reason why manually configured IIDs whould have to be 64 bits. Then there is SLAAC. I'm fully on board to say that SLAAC should require 64 bit IIDs for ever. So it seems to me that there are operators that want to use longer prefixes with manual configuration and you want to keep SLAAC at 64-bit. That sounds perfectly consistent. I can't think of any reason why IA_NA or manually configured IIDs would have to be 64 bit. So a text like 'implementations MUST support 64-bit IIDs for SLAAC. implementations SHOULD support other lengths for other ways of configuring addresses (IA_NA, manual).' should work. Or did I miss something?
