An IP address is a unique number used to identify a computer network, allowing it to communicate with other networks online. Traditional IP addresses use IPv4 networking and display as a 32-bit number. Due to IP number limits, exclusive IPv4 addresses are in low supply, as of 2015. As a result, Internet networks are shifting towards IPv6 technology, which allows a nearly infinite number of IP address combinations.
