What is the different between internal DNS and external DNS?

Is there a way to have a dns server running server 2003 resolve an ip address to an external domain name?

• I am running a unix based corprate program in my office that gathers data from our remote locations that is run by a 3rd party distributor. Right now the program dials out to the remote locations using a dial up modem, but the software has the ability to do it through tcp/ip on a telnet connection. The problem is, the connectio applet for data collection is propritary and i have no way to modify it and it cannot resolve domain names, only ip addresses. The DNS server that this unix box is pointed at is running server 2003 and i was wondering if it is possible to "spoof" and ip address in the DNS server so rather than having the Unix machine be responsible for resolving the name, the DNS server translates a fake local IP address to a domian name.. Example: If i type into a terminal emulator "connect to 100.100.100.10 on prot 23" is there a way that when that request hits the DNS server it redirects the request to www.yahoo.com on port 23

• Answer:

  Yes there is a way.. if you have access to a dns server that the software uses to resolve then it would be VERY easy.. Personally.. I wouldnt do 10.10.10.10 to yahoo.com... I would to 10.10.10.10 to destination IP.
