Thanks for taking the time to explain all of that. What I've found is
that most of the address I can find are A, MX . As a result, when I run a
DNSENUM against my domain externally most A records that point to our IP
addresses.
That's normal. That's what A records are.
Obviously I would like to hide these (especially ones like
remote.blah.org and vpn.blah.org).
You can't hide DNS records. DNS is public information. Everyone can see it.
If you don't want a host name published then don't publish it. But then
NOBODY can find the host's IP address including your own users. It's all or
nothing.
Get the DNS cricket book.
