DynSite for Windows   -   Version   1.11 (build 544.1)

DynSite automatically updates your current dynamic IP
address on one or many dynamic DNS services or by
email 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 DNS-like address (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 connect.
