An IP address (Internet Protocol 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 addresses are the most common and are typically represented in dotted-decimal notation, such as 192.168.1.1. IPv6 addresses are newer and are represented in hexadecimal notation, such as fe80::1.
