Make Servers Always Available by Mapping a Hostname to a Dynamic IP Address

Make sure the web site or other kind of Internet server you run at home is always available to the world.

If you run your own web server, mail server, or other kind of server at home and are connected to the Internet via a cable modem or DSL modem, people frequently might not be able to connect to your server. That’s because, typically, broadband ISPs assign you a dynamic IP address that changes regularly, even if you don’t turn off your PC. Because your IP address constantly changes, there is no way for people to connect to you. One day its IP address might be 66.31.42.96, the next it might be 66.41.42.136, and if people don’t know your server’s current IP address they won’t be able to find it. You won’t be able to solve the problem by getting your own domain (such as www.gralla.com)
