This is the classic Versión of the TZO Client software which first introduced the idea of linking a domain name to a Dynamic IP address. TZO uses true dynamic DNS client/server technology and has one of the most reliable infrastructures. 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 Casa or office. The 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 solution. Simple and Easy to use.
