DynSite

DynSite for Windows is an automatic IP updater, it can update your current
dynamic IP address on one or many dynamic DNS services so that anyone can
contact you (in NetMeeting, CU- SeeMe, etc.) or access your FTP server or
Web site on your own computer using a fully qualified domain name
(e.g. myhost.dhs.org, where myhost is a name of your choice) which will
never change instead of using your IP address that changes each time you
reconnect. Your friends or relatives will always be able to call you, whatever
your IP address is, without needing to know it.
All you have to do is to sign up with one of the supported dynamic DNS
services and to run DynSite for Windows.
