Is it possible to add some custom subdomains, for an existing domain name that's hosted on another DNS, for our internal DNS?
Currently, our developers at our office hack their own host files by adding in some custom subdomains like the following :-
and we own the domain
foo.com BUT it's not hosted by us, but a 3rd party.
BUT, we do have an internal DNS server which is mainly being used as a CACHE server. Of course, we can add our own
forward lookup zones. But if I do that, I'm afraid that all the EXISTING data for that real zone will not be used.
eg. imagine the zone
foo.com has the following (but I don't know about it)
if I don't add that data to the zone, then when a user tries to access that domain .. it will not resolve. (and lets not talk about keeping the zone manually up-to-date ... cringe!)
So! is it possible to inherit (ack - my programming hat snuck back on) or to copy or sync a domain ... and then I manually add those 2 extra subdomains in for that zone .. but of course unless a person knows to use my internal DNS ... they will never been available to anyone.
Is this possible?
