We use DNS together with DHCP for our clients (and actually some
of the servers as well). The idea is that the DHCP client reports
its hostname for update of our own DNS server. In the service address
field we use the host name, not the IP address. In DHCP/DNS lingo this
is called Dynamic DNS Update (DDNS).

Hope this helps
