DNS and DC and internet hostname are the same, is that a problem?
Posted on 2002-04-06
My system has, for some obscure reason (don't ask!) the same name for its forest/dc as for an internet domain name that must be resolved externally. That said, my local DC and my remote hostname, that are located on the same server, have two (actually three) distinct A records, as shown below. Currently, I think it works correctly, but I'm afraid this is going to cause me trouble when I start setting up Apache (or any other webserver).
These are as it is configured locally:
A 10.0.0.10 MyDomain.com
A 10.123.456.789 MyDomain.com
This is the external configuration (at remote DNSs):
A 213.123.456.789 MyDomain.com
Note that the last three values are the same on the remote and the second local address. For some (logical) reason, the local auto-registration replaced 213 with 10 to fit it in the local subnet.
The question is, when I ping/trace mydomain.com, where do I go? Can I force it to go extern? But sometimes, or often, I need the domain name, not the internet host. Have I created a potential conflict, or is there a simple answer to all those questions?
Thanks in advance,
