An IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. IP addresses have two main functions: host or network interface identification and location addressing.
There are two main types of IP addresses: IPv4 and IPv6. IPv4 addresses are the most common type of IP address and are made up of four numbers separated by periods, such as 192.168.1.1. IPv6 addresses are the newer type of IP address and are made up of eight hexadecimal numbers separated by colons, such as 2001:0db8:85a3:08d3:1319:8a2e:0370:7334.
