Internet address, IP address
Any computing device that uses the Internet Protocol (IP) must be
assigned an internet or IP address. This is a 32-bit number assigned
by the system administrator, usually written in the form of 4 decimal
fields separated by periods, e.g., 192.9.200.1. 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.
