	RFC 2461 (rfc2461) - Neighbor Discovery for IP Version 6 (IPv6)
		In particular, whether packets sent to a neighbor are reaching the IP layer on the neighboring machine and are being processed properly by the receiving IP layer.
		For neighboring routers, reachability means that packets sent by a node's IP layer are delivered to the router's IP layer, and the router is indeed forwarding packets (i.e., it is configured as a router, not a host).
		The function is chosen so that IP addresses which differ only in the high-order bits, e.g., due to multiple high-order prefixes associated with different providers, will map to the same solicited-node address thereby reducing the number of multicast addresses a node must join.

	IP Version 6 (IPv6)
		IPv6 was recommended by the IPng Area Directors of the Internet Engineering Task Force at the Toronto IETF meeting on July 25, 1994 in RFC 1752, The Recommendation for the IP Next Generation Protocol.
		Internet Protocol Version 6 is abbreviated to IPv6 (where the "6" refers to it being assigned version number 6).
		IPv6 is a new version of IP which is designed to be an evolutionary step from IPv4.

		This new version, called IP Version 6 (IPv6), resolves unanticipated IPv4 design issues and is poised to take the Internet into the 21st Century.
		The Protocol field is used to demultiplex an IP packet to the upper layer protocol.
		Upon receipt of the multicast Neighbor Advertisement with the Target Address field set to the IP address for which duplication is being detected, the node disables the use of the duplicate IP address on the interface.

	IPv6 - Wikipedia, the free encyclopedia
		IPv6, or Internet Protocol version 6, is a data-oriented network layer standard used by electronic devices to communicate data across a packet-switched internetwork.
		There are too few IP addresses available for the future demand of device connectivity (especially cell phones and mobile devices).
		The now-obsolete initial version, described in RFC 1883, differs from the current proposed standard version, described in RFC 2460, in that 4 bits have been reassigned from flow label to traffic class.

		The current version of IP (known as Version 4 or IPv4) has not been substantially changed since RFC 791 was published in 1981.
		The Protocol field is used to demultiplex an IP packet to the upper layer protocol.
		Version – 4 bits are used to indicate the version of IP and is set to 6.

		This means that IP is a primary vehicle for a vast array of client/server and peer-to-peer communications, and the current scale of deployment is straining many aspects of its twenty-year old design [4].
		IP spoofing is known to be one of the most common forms of denial-of-service attack; with IPv4 it is typically impossible for a server to determine whether packets are being received from the legitimate end node.
		IP addresses need to be configured for new hosts, for hosts that change location, and for hosts connected to physical networks that receive address modification (e.g., a new prefix).

	ONLamp.com: Introduction to IPv6
		Switching to a different protocol version that does not have these problems of course requires for a "better" version to be available.
		Version 6 of the Internet Protocol (IPv6) fulfills future demands on address space, and also addresses other features such as privacy, encryption, and better support of mobile computing.
		When mentioning mobile devices and IP, it's important to note that a special protocol is needed to support mobility, and implementing this protocol -- called "Mobile IP" -- is one of the requirements for every IPv6 stack.

	Waiting for IP version 6 - ISP Column, January 2003
		This effort was intended to examine the issues associated with the scaling of IP routing and addressing, looking at the rate of consumption of addresses and the rate of growth of the inter- domain routing table.
		IPv6 has had a variety of names - the original IAB documents refer to IP version 7, working on the assumption that the protocol numbers 5 and 6 were already in use in research networks.
		The final word from the IANA was that protocol number 6 was unused, and the final specification was named version 6 of the IP protocol.

	DomainsAreFree - Definition of IP Address
		An IP Address is a unique number, akin to a telephone number, used by machines (usually computers) to refer to each other when sending information through the Internet.
		Depending on one's Internet connection the IP address can be the same every time one connects, a static IP address, or different per session (but the first part being the same each time): a dynamic IP address.
		As there are only a limited number of 32-bit IP addresses currently available to be allocated, with rising demand for new devices, including personal communicators for up to 6 billion people world-wide, there is a real prospect of the world running out of IP addresses.

	Internet Addressing and Routing First Step > IP Version 4 and IP Version 6
		IP version 4 (IPv4) has not changed much since it was defined in 1981.
		The reason the actual number of usable IP addresses is less than the maximum is because the broadcast and "this" network addresses cannot be assigned to hosts.
		IP version 6 (IPv6) uses 128 bits and it is interesting to investigate if 128 bits satisfies the need for more IP addresses.

	IP version 6, by doug@mscs.mu.edu (Site not responding. Last check: 2007-10-17)
		There are quite a few differences between IP version 4 and IP version 6, other than the increase in address lengths.
		These changes were suggested by experience with the IP protocol over the 20 years since it was first conceived.
		That is, each header carries a "next-header" field, and several of these can be IP extension headers, until the final one, which must be a header for one of the protocols "on top" of IP such as ICMP, TCP, or UDP.

	Seminar - IP version 6
		IP version 6 (IPv6) is a new version of the Internet Protocol based on IPv4.
		IPv6 increases the IP address size from 32 bits to 128 bits, to support more levels of addressing hierarchy and a much greater number of addressable nodes, and simpler auto-configuration of addresses.
		A new type of address called an "Anycast address" is defined to identify sets of nodes where a packet sent to an Anycast address is delivered to one of the nodes.

		Advantages of Version 6 The biggest advantage of IP version 6 is the increase in the number of IP addresses available.
		The old version was 32 bit and the number of possible IP addresses was equal to 232, the new protocol is 128bit and allows for 2128 possible addresses.
		The address is significantly longer, so we discussed the issue of longer addresses being harder to recall, but it was mentioned that the network part of the IP is not required, so it is not significantly harder to recall.
