What is internet protocol or IP address

source

An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g.,

computer, printer) participating in a computer network that uses the Internet Protocol for
communication. An IP address serves two principal functions: host or network interface identification
and location addressing. Its role has been characterized as follows: "A name indicates what we seek.
An address indicates where it is. A route indicates how to get there."
IP addresses are binary numbers, but they are usually stored in text files and displayed in human-
readable notations, such as 172.16.254.1 (for IPv4), and 2001:db8:0:1234:0:567:8:1 (for IPv6).
