IP
Internet Protocol. The protocol defined in RFC 791.
IP address
A 32-bit number assigned by the system administrator, usually written in the form of four
decimal fields separated by periods—for example, 192.9.200.1. Any computing device
that uses IP must be assigned an Internet or IP address. Part of the Internet address is the
IP network number (IP network address), and part is the host address (IP host address).
All machines on a given IP network use the same IP network number, and each machine
has a unique IP host address. The system administrator sets the subnet mask to specify
how much of the address is network number and how much is host address.
IP address prefix
An IP address number that, when paired with a netmask length, represents a range of
addresses rather than a single IP network. For example, the prefix and netmask length
128.0.0.0/8 describe all networks whose IP addresses begin with 128. See also
