Hi all,

FWIW, more discussion on the problem space can be found here: http://www.ietf.org/mail-archive/web/v6ops/current/msg16276.html or http://tools.ietf.org/html/draft-kaliwoda-sunset4-dual-ipv6-coexist-01#section-2.

draft-wing-* solves this issue for dhcp-enabled networks.

Cheers,
Med

>>Abstract:

>>   can use an optimal DNS server for resolution.
