Time, and space—address space that is—are running out. Internet Protocol version 4 (IPv4), the networking standard on which the Internet has been built, is expected to reach its IP address limit of roughly 4.3 billion in a few years. While most enterprises can survive for now with just a handful of IP addresses (thanks to Network Address Translators—NATs—which allow multiple devices to be connected to the public Internet with a single public IPv4 address), the burgeoning number of Internet-connected mobile devices and non-traditional objects like cars, appliances and smart meters demands that the Internet’s phone book expand its listings. Enter Internet Protocol version 6 (IPv6). IPv6 was designed to succeed IPv4 and accommodate the future growth of the Internet by providing a much larger address pool than IPv4.
