An Internet Protocol (IP) Address is the unique numeric identifiers that are needed by every device that connects to the Internet. There are a shared common resource that must be managed carefully to ensure the continued growth and stability of the Internet. Most of the Internet is currently addressed with IP version 4 (IPv4) addresses. IPv6 addresses are also in use, but not yet to the same extent. IPv6 is a more recent protocol, offering a much larger address pool than IPv4. However, IPv6 is not intended as a direct replacement for IPv4. Rather, the two address protocols are able to be used together across the Internet. (Source: www.internetsociety.org/)
