I?m wondering if there’s a way to for a DNS server to answer clients for a zone (mydomain.com) even if it’s not the primary DNS server for that domain.
What I’d like to end up with is this. From inside an internal network when looking up a.mydomain.com, the internal IP would be returned by the DNS (10.12.1.x) but when looking up any other host (that wasn’t explicitly specified) it would look it up in the primary DNS server.
What is this process called? Relaying? I guess partial relaying since certain hosts are resolved locally… Is this possible? If so would this be possible using MS Active Directory? I think I’ve seen this done at previous sites but the sys admin here is adamant that this isn’t possible unless the internal server is the primary DNS.
Thanks in advance,
Alex
