host resolving to an IP not in the zone

[josephc]

Ok, this is just weird:

> nslookup -q=a health.healthcommunities.com dns.etards.net
Server:  h0000c5785fb6.ne.mediaone.net
Address:  66.31.249.69

Non-authoritative answer:
Name:    health.healthcommunities.com
Address:  192.168.1.10

But a lookup against the master server:

> nslookup -q=a health.healthcommunities.com health.healthcommunities.com
Server:  health.healthcommunities.com
Address:  63.127.8.210

Name:    health.healthcommunities.com
Address:  63.127.8.210


dns.etards.net/h0000c5785fb6.ne.mediaone.net is not in anyway related to
healthcommunities.com, it just happens to be another DNS server I manage.

The zone for healthcommunities.com contains absolutly no reference to
192.168.1.10. However, that IP is the internal address for
health.healthcommunities.com in its home network. But again, that IP
address is not stated anywhere in any DNS records and it never, ever has
:)

So does anyone know where it could be coming from? It does not appear to
be cached info, and so far it only happens to queries against that DNS
server, but I am worried that it could be happening elsewhere and I just
don't know it.

thanks
