How to configurate DNS server to work virtually with 3 servers, , and only 1 public IP address available?

I have 3 servers, 1 router w/swich, 1 public IP address, and DNS application running on the server.

Is it possible to configurate the DNS to work with this, and how do I do it?
One of servers is runing Linux, other two win 2k.

There are a couple of ways to do this. What apps are running on each server? For example if one is to be a web server and another an email server you can easily just forward port 25 to one and port 80 to the other.

If they are all to be web servers then you need to forward all requests to the DNS server where it can them resolve the web address to the correct internal IP.

They are all web servers. The DNS app is runnnig on one of these 3!
Is it a problem?

No just forward traffic from your router to the machine hosting the DNS service. Then the DNS service will resolve their hostnames/domain names to their local IP address on your network. In the internet domain registar simply point all your registered domain names at the same IP.

Question:
<<In the internet domain registar simply point all your registered domain names at the same IP.>>
Why? There are ca 60 domains in total, and I will divide them on 3 servers. But there will be 3 different servers, and 3 IP addresses. Why use the same ip?

Gareth GudgerCommented:
Because you only have one public IP address. The domain registrar is the public domain name reolsution authority I was referring to (like InterNIC or register.com). The 60 domain names registered on the internet will resolve to your public IP (your network) which will be sent to the router, forwarded to DNS and resolve the the separate private IPs.

I am using DNS software on win 2000 server. If I add 192.168...... instead of my public IP, then no page is found.

How exactly to do it?
