There is one (regarding rules, not regarding labels): a TLD is a domain like any other. It has nothing special, technically speaking. Since IETF is supposed to work in the field of technology, not politics, I would object to any registry that lays down special rules for TLDs, besides the normal RFC 1034/1123/2181 rules (which apply to every domain). Reserving TLDs (like ".example") is a different thing: we don't create new rules, we just use our privilege to get a TLD without paying 100,000 US $ to ICANN. _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
