What is the necessity of IP Address?

An Internet Protocol (IP) address is a numerical
identification (logical address) that is assigned to devices
participating in a computer network utilizing the Internet
Protocol for communication between its nodes. Although IP
addresses are stored as binary numbers, they are often
displayed in more human-readable notations, such as
192.168.100.1 (for IPv4), and 2001:db8:0:1234:0:567:1:1 (for
IPv6). The role of the IP address has been characterized as
follows: "A name indicates what we seek. An address
indicates where it is. A route indicates how to get there."
Originally, an IP address was defined as a 32-bit number and
this system, now named Internet Protocol Version 4 (IPv4),
is still in use today. However, due to the enormous growth
of the Internet and the resulting depletion of the address
space, a new addressing system (IPv6), using 128 bits for
the address, had to be developed. IPv6 is now being deployed
across the world; in many places it coexists with the old
standard and is transmitted over the same hardware and
network links – courtesy Wikipedia
