You can do that in the scripts. You probably want to store the IP and
hardware address of the server or some such as well.

Yup, modify the script to your hearts content. You probably want to make
sure that A) The IP is not in use and that B) The server is on the
network. If you are doing B), you can store multiple caches.
An alternative to B would be to store some other address on the network,
ie, your default gateway.
