Why are domain names rather than IP addresses used in name server records?

How come when setting name server records, so you can work out what IP address a domain belongs to, you always use domains?

What ~quack said, plus most operating systems will hold results in cache for some time. The very first DNS lookup would incur the small time cost of looking up the IP, subsequent queries will use the cached results.
