My company just moved our office, mainly to take advantage of DSL access. Previously we were on Starband and although they are supposed to be dynamic addressing, my IP address only changed once in two and a half years.

Now that I've moved over to Bellsouth Business DSL, we get a new IP address every time we drop our connection for one reason or another.

I'd like to know what are the best/cheapest Dynamic DNS services out there so that I can access my servers from remote locations. Any help or insight is greatly appreciated.
