Question : How to input a host outside the domain to the dns server?

We're running a couple of zones behind a firewall.
The first is zone 50.0.0.0, which is an internal zone.
The second is zone 51.0.0.0, which is a dmz zone.
The two zones are connected, and using the ip address on the browser will currently allow users in 50.0.0.0 to access the services in 51.0.0.0

Now its become necessary for our internal users inside 50.0.0.0 to be able to use their browser and type: www.dmz.com and have it pointed to 51.0.0.1.
We want to achieve this by using internal routing and not have the users access the internet to access www.dmz.com.

In the 50.0.0.0 (internal zone), we're running a windows 2003 DNS & DHCP (AD).
In the 51.0.0.0 (dmz zone), we're not running any dns services yet.

The question is, where and how can we allow users in 50.0.0.0 to access 51.0.0.1 by simply typing www.dmz.com on their browser?

Thank You

In the forward lookup zone, you'll want a Primary. For the zone name, use the domain name you want to resolve to.

Once the zone is created, select it and right-click in the white area to the right. Create a new A record, and for the host value leave it blank (it will respond on all requests) and forward it to the target IP.

Keep in mind, if this is an internet/intranet domain that has other host resolution values, you will need to define them manually.

Essentially, you are telling your DNS server it can act as an authorative responder for the domain you create. So if you want www.domain.com to goto 10.0.0.1, and server1.domain.com to goto 10.0.0.10, you need to define that.

An A record is anything that appears before the domain name ..com/net/local/etc
