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