How is an IP address defined?

An IP address is indeed defined as a unique numerical label assigned to each device on a network that uses the Internet Protocol for communication. This unique identification allows devices to send and receive information through the network effectively.

IP addresses serve a crucial role in routing data, ensuring that the information sent over the internet reaches the correct destination. Each device connected to a network, whether it’s a computer, smartphone, or printer, needs an IP address to uniquely identify it among millions of devices connected globally.

The concept of uniqueness in an IP address is vital because it prevents confusion or data misdirecting, enabling reliable communication between devices. Essentially, without a unique identifier like an IP address, the internet would not be able to function as each device would not have a defined location in the network hierarchy.
