In essence, IP addresses are the identifier that allows information to be sent between devices on a network: they contain location information and make devices accessible for communication.
An IP address is a string of numbers separated by periods. IP addresses are expressed as a set of four numbers — an example address might be 126.96.36.199.
Example of usage – “While studying about the internet, she discovered that each of her electronic devices, that connected to the internet had a unique identification number on the internet, known as the IP address. Anyone could track her device and check its activity if they had the IP address of the target device.”
