-----Original Message----- From: Brian E Carpenter [mailto:brian.e.carpenter@gmail.com] > Actually, by removing all the exceptions in the -09 text, I > contend it is a considerable semantic simplification. I agree that the "exceptions" could be reworded, because the issue is far simpler now than what the "exceptions" imply. IIDs used in SLAAC, LLA, or ULA, must be 64 bits long. Otherwise, there are no restrictions, other than the total address length must be 128 bits. So this avoids creating another new subtlety for IPv6, that serves no useful purpose (IMO). One of the biggest changes in 4291-bis, which should carry over to RFC 2464 and others, has been deprecation of the use of EUI-64. The consequence of that change is that this 64-bit IID requirement becomes diminished, and by extension, the previously-listed exceptions increase. So now, rather than list the exceptions, we should be listing where 64-bit IIDs are still required. I've no objection to using language like "default" or "recommended," though. Bert
