HostsEditor is small useful tool that manages IP <-> name mapping (hosts file editor :). So you could specify an IP and a matching name and it will be set up within your system.

For example, if your e-mail account has long URL-name match its IP to the "mail" word. Just then you may see your mails by typing "mail" into web-browser! Also it works for FTP, Ping, Traceroute, ... If you don´t know the IP, the application will determine IP itself. Help is available by "F1".
