Computer and Internet Protocol Address Verifier

A computer and internet protocol address verifier makes sure that your computer is able to connect to the internet. It does this by checking the number - called an IP address - assigned to your computer. Every computer and other devices like printers, mobile phones, and tablets have their own IP address. The verifier makes sure your computer's IP address is unique so that it can connect to the internet.
