Excellent suggestion!  I've used dyndns.org free service for about 6
years: more reliable than Qwest's DSL service.  

You need to run a client program - checks your ip every few minutes and
updates DynDns's DNS when there's a change.  You also have to update
every 15 days even if there's no change (they don't want to maintain
records for dead names).  

There's a number of 3rd party clients available.  I can recommend
ddclient (perl).
