DNS Question: How to make a public web site resolve to localhost 127.0.0.1
Posted on 2006-06-02
I have a Windows Server 2003 Standard running DNS now. This is my DC as well and is one of two DNS servers that handles DNS queries for users on our domain. The other one is a DC that also is running Windows Server 2003 Standard. Both are SP1 and fully patched.
What I want to do is to put another layer in the mix of blocking IM traffic on our network. Right now I have done all I can at the firewall level. I want to setup the DNS server so if request for popular IM servers are made it resolves them back to the localhost 127.0.0.1 (loopback) and never hits the network.
Does that make sense? For instance, if a user fires up their IM software and it starts trying to communicate to it's authentication server at "my.stupid.im.com" address, I want the DNS server to resolve that back to the localhost at 127.0.0.1.
Can someone give me step-by-step on how to do this? Assume I'm ignorant with configuring DNS (trust me I am).
Thanks in advance!
