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.
