We are redirecting some of our own domain names back to their private IP's using our internal DNS server. This works fine. Right now we have it setup so each fqdn we want to redirect is its own primary zone.
are all primary zones.
I'd like to set it up so that domain.com is a primary zone and each sub domain is just an A record. If I do that, queries for the sub domains I haven't redirected aren't forwarded and don't resolve. What can I do to make that zone forward queries for non existant sub domains? I also want the zone replicated to all of our internal DNS servers. Or, is there a better way to accomplish the redirection?
