WinIP allows Internet users to access your computer via a static host name (e.g. mycomputer.thatip.com or mydomain.com) even though you may have a dynamic IP address. This lets others access your computer the same way every time, instead of having to enter a different IP address every time you reconnect to the Internet. Your machine will get a fully qualified domain name. Even if your computer's Internet address is dynamically assigned, people can connect to your machine's FTP, WWW, IRC or other server by using your single hostname, recognized on the entire Internet. It can manage multiple hostnames pointing to different IP addresses.
