You are half right.  Dynamic DNS is used for updating a DNS server to
have the correct IP for a specific host.  This can be done by sites like
dyndns.org etc.  You don't need a router that supports that.

But you DO need DDNS on a local level.  It's the same thing.  client
machine tells dns server 'this is my new ip'.

Unfortunately I can't give you particular software suggestions but I had
my guys do it with thin clients over 5 years ago.  I think we had the
thin clients run a script after getting an IP that talked to a daemon on
the DNS server to update the records.

Our solution was home grown but I've seen the same thing mentioned with
the moniker DDNS on the net more recently.  There may be some DDNS
features in the major DNS servers in use like bind, djbdns, etc.
