World IPv6 Launch
IPv6 is an Internet Layer protocol for packet-switched internetworking and provides end-to-end datagram transmission across multiple IP networks, closely adhering to the design principles developed in the previous version of the protocol, Internet Protocol Version 4 (IPv4). IPv6 is the successor to the first addressing infrastructure of the Internet, Internet Protocol version 4 (IPv4). In contrast to IPv4, which defined an IP address as a 32-bit value, IPv6 addresses have a size of 128 bits. Therefore, IPv6 has a vastly enlarged address space compared to IPv4. IPv6, the next-generation protocol, provides approximately 340 undecillion IP addresses (see Figure 1), ensuring availability of new IP addresses far into the future, as well as promoting the continued expansion and innovation of Internet technology.

Each IPv6 route structure is composed of an IPv6 address, a prefix length (1 - 128), an IPv6 next hop address (which may be zeroed out if there is no next hop), and a metric. If the metric is 0, NM will choose an appropriate default metric for the device.
