What is IP Address?

A unique numerical label assigned to each device on a computer network for identification and communication.

An IP (Internet Protocol) address uniquely identifies a device on a network. IPv4 uses 32-bit addresses (e.g., 192.168.1.1) providing about 4.3 billion addresses. IPv6 uses 128-bit addresses (e.g., 2001:db8::1) for virtually unlimited addresses.

IP addresses can be public (internet-facing) or private (local network). Private ranges include 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.
