I feel compelled to point out that there are 2 problems with these services (dyndns) first is that nameservers cache lookups and you may have some convergence problems if you often change IP nums, but more importantly the reverse address lookup will still remain fixed at whatever the ISP has it set to. This can be important if your trying to run a mailserver that directly transmits mail, as some anti-spam filters that do reverse address lookups will block mail in which both a forward and reverse lookup don't match.
