You need to investigate Dynamic DNS. You can configure ISC dhcpd to send
updates to a running BIND named so when a client gets a lease, their
hostname goes into the DNS zone, etc. In some cases you can get the
client machines to update the DNS instead/as well, but I'd question how
clever that is in some cases...
