An IP address is a unique address that helps in transferring, finding, and receiving data from one machine to another. The address is made up of a string of numbers separated by full stops. It is the unique identification number for each computer using the internet. Every device that uses the internet has its own IP address, which allows it to be found and communicate with other devices. For example, when you send an email, your computer uses its IP address to find the recipient’s computer and deliver the message. IP addresses are essential for the smooth functioning of the internet, and they provide a vital link between devices all over the world.
