Does anybody know how to make a Cisco Router act as a DNS server? Let me clarify that I'm not talking about relaying/forwarding DNS requests, from the router to another system that resolves DNS. I want the router to listen on port 53 for DNS queries; once the query is received the router should look to its own host table (Both perm and cached entries) and then return a name resolution (IP address) to the querying host.

I don't think that you can do this. Why would you want to?
Chris.
The only Cisco router-like device I know of that can do this is Distributed Director. But it's pretty limited in the types of queries it can handle.

Why, with the "ip dns server" command, naturally.
