Internal AD DNS record for external domain

[Bucket]

Greetings all,
I have inherited an internal Active Directory domain with .net.au suffix. So
our INTERNAL domain is domain.net.au. Everything is running fine as I update
internal records to match external DNS updates (www records etc).

However, I have to create an internal record for domain.com rather than
domain.net.au. The record must be .com as a program has it hard coded to
access this address. I can get around the issue by editing the hosts file on
a single machine (this works), but as multiple people need to use this
program, a DNS record would be better suited.

There is probably an easy fix, but I just can't find / think of it at the
moment. Is there a way to create a record for ftp.domain.com inside my
domain.net.au domain?

External DNS records are fine, but our internal machines need to go to the
internal IP address rather than the external IP address (which then port
forwards to the internal IP).

Hope this makes sense,

Bucket.

Create a new domain within the internal dns server and point this host name
to the internal server. That simple.

Hi there, you can't create a record for domain.com on yopur dns server
because you don't have that zone hosted on your server. You need to create
the record on your external dns hosts server that is authoritative for the
domain. N.B that the external dns host can still return you a local ip
address if you want it to.
Does that solve the problem or are you trying to resolve a dns name that
already exists to something other than its current IP address? If so you
could create a zone for domain.com on your dns server and populate the
records manually, however this will then cause all the DNS requests for that
zone to be resolved or returned as non-existent by that server and they will
not be forwarded.
The problem is hard coding a domain name (especially a.com one) into a
programme that wants it resolved to an internal IP address is not very
clever!!!

The best solution is to create a Forward Lookup zone for the Full DNS Domain
name, i.e. ftp.domain.com, then in that zone create one new host (A) record,
leave the name field blank, and give it the IP you need.
Alternately, you can create a zone named domain.com and add a host named
ftp with the IP, the problem with that solution is that you'll need to
create records for every other name in domain.com you will ever need to
access. IMO, it is a better solution to create zones only for the names that
need to resolve differently, than it is to try to create records for every
name in the external DNS. Some of these can be CNAMES that point to multiple
dynamic A records.
