That's a weird question. :-) I'm using OpenDNS, so I get:

intrepid{~}% nslookup inet6
Server:         127.0.0.1
Address:        127.0.0.1#53

Non-authoritative answer:
Name:   inet6.warped.com
Address: 208.67.219.132

Is that what you wanted to know?

FWIW, this happens in a VMWare box on another network as well (where I
don't think I even configured /etc/myname or resolv.conf).
