IPv4 (Internet Protocol Version 4) is the fourth revision of the Internet Protocol (IP) used to to identify devices on a network through an addressing system. The Internet Protocol is designed for use in interconnected systems of packet-switched computer communication networks (see RFC:791).
An Internet Protocol (IP) address is a numerical label used to identify a computer or device within a network. Checking the computerâs IP address is the first step to determine if your computer is properly communicating with your router. NOTE: Make sure your computer is connected wired or wirelessly to your router.
