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. IP addresses are written as a set of four numbers separated by periods, such as “192.168.1.1”.
There are two main types of IP addresses: IPv4 and IPv6. IPv4 is the most common type of IP address, and it uses a 32-bit number to identify each device. IPv6 is a newer type of IP address, and it uses a 128-bit number to identify each device.
