What is an IP address primarily used for?

An IP address is primarily used to identify each computer or device on a network. It serves as a unique identifier for devices, allowing them to communicate with one another over the Internet or a local network. Each device connected to a network is assigned an IP address, which plays a crucial role in routing data packets to the correct destination. This identification is essential for establishing connections and ensuring that data sent from one device reaches the intended recipient without confusion.

For example, when you send an email or visit a website, your device uses its IP address to follow the correct pathway through the network to find and connect with the recipient’s device. By providing a unique address to each machine, IP addresses enable efficient and accurate communication across global networks.
