IP address

**IP address**

An IP address (Internet Protocol address) is a unique string of numbers assigned to every device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: identifying the host or network interface and providing the location of the device in the network. IP addresses are essential for routing data between devices across the internet or within local networks. There are two primary versions in use today: IPv4, which consists of four sets of numbers separated by periods, and IPv6, which uses a longer alphanumeric format to accommodate the growing number of devices online. Understanding IP addresses is fundamental for network management, security, and troubleshooting.
