I use dyndns and fine it very satisfactory but be very careful about
using your router to update it for you. I tried this using a Netgear
router and got blacklisted for submitting changes every few minutes.
Go to the dyndns site and find a client. For Mac OS X DNSUpdate works
flawlessly and unobtrusively.
