An IP address is a unique identifier which defines the location of a computer on the Internet. It also gives information on the used provider. IP addresses are 32-bit addresses composed of four separate numbers from 1 to 255, separated by dots (.).
Every IP address is mapped to a special host name, as most users find it easier to remember names than to remember numbers.
Any address starting with http:// or ftp:// is simply a masked IP address. WISE-FTP accepts IP addresses, as well as host names.
