RFC 2460 - IP version 6 (IPv6) is a new version of the Internet Protocol,<br/>   designed as the successor to IP version 4 (IPv4) [RFC-791].  The<br/>   changes from IPv4 to IPv6 fall primarily into the following<br/>   categories:<br/><br/>      o  Expanded Addressing Capabilities<br/><br/>         IPv6 increases the IP address size from 32 bits to 128 bits, to<br/>         support more levels of addressing hierarchy, a much greater<br/>         number of addressable nodes, and simpler auto-configuration of<br/>         addresses.  The scalability of multicast routing is improved by<br/>         adding a "scope" field to multicast addresses.  And a new type<br/>         of address called an "anycast address" is defined, used to send<br/>         a packet to any one of a group of nodes.<br/><br/>      o  Header Format Simplification<br/><br/>         Some IPv4 header fields have been dropped or made optional, to<br/>         reduce the common-case processing cost of packet handling and<br/>         to limit the bandwidth cost of the IPv6 header.<br/><br/>      o  Improved Support for Extensions and Options<br/><br/>         Changes in the way IP header options are encoded allows for<br/>         more efficient forwarding, less stringent limits on the length<br/>         of options, and greater flexibility for introducing new options<br/>         in the future.<br/><br/>      o  Flow Labeling Capability<br/><br/>         A new capability is added to enable the labeling of packets<br/>         belonging to particular traffic "flows" for which the sender<br/>         requests special handling, such as non-default quality of<br/>         service or "real-time" service.<br/>
