An IP address is a unique identifier that defines the location of a computer on the Internet. It also includes information about the service provider and the location of the server. There are two types of IPs currently in use: the old IPv4 and the new IPv6.
IPv4 addresses are 32-bit addresses composed of four separate numbers from 1 to 255, separated by dots (.).
IPv6 addresses are 128 bit addresses composed of blocks of numbers and letters, separated by a colon (:).
Since most users find it easier to remember names than numbers, IP addresses are usually mapped to a special host name.
Any address starting with http:// or ftp:// is simply a masked IP address. WISE-FTP accepts IP addresses as well as host names.
