TZO uses true dynamic DNS client/server technology to fix static domain name to a dynamic IP address. This allows Internet users with Cable, DSL, and dialup Internet connections to host their own web server, FTP server, mail server, game servers, or any other TCP/IP service from a PC at your home or office. The new TZO Lite client software has the ability to handle multiple domains and you can also select which network interface to use. TZO Lite is a small and efficient client for those that want a pure dynamic DNS client without the added weight of a web and photo server. Simple and Easy to use.
