Hi Rick, I'm pretty sure that's not the way to go. As Olle pointed out a SIP URI with domain could point, after RFC 3263 resolution, to many transport:address:port, some of them could be IPv4 and others IPv6. Your proposal would indeed break existing implementations. If for example alice uses just IPv4 and bob just IPv6, and both use and register in a proxy/registrar with IP dual stack, alice should be able to call bob's AoR (sip:bob@example.net) without knowing that bob is using IPv6 or not. This is already possible with current specs but it would be not possible with your proposal. Regards. -- Iñaki Baz Castillo <ibc@aliax.net>
