I don't think this has anything to do with RFC 6761, so ... I tend to agree, but it did get caught up in the 6761 maelstrom For a very long time, two letter TLDs have been assigned to countries and other geographic entities per the ISO 3166 alpha-2 list. The earliest mention I can find is in RFC 920 in 1984, and even then the wording suggests that the usage was well settled. The codes AA, QM-QZ, XA-XZ, and ZZ are "user assigned" and will never be used for countries. Last year Ed Lewis wrote an I-D proposing that XA-XZ be made private use and the rest future use, but as far as I can tell it never went anywhere. 6761 "discussions" sidetracked it I believe. I've been telling people that if they need a fake private TLD for their local network they should use one of those since it is exceedingly unlikely ever to collide with a real DNS name. Am I right? I'd really like to say yes, but ISO-3166/MA appears to have removed references to "User Assigned" in their official ISO-3166 two letter code webpage. I'm trying to understand if they've changed their mind, but no answer yet. Regards, -drc
