In 1983 when IPv4 was first deployed, its capability of a little over 4 billion unique numbers seemed sufficient. As of 2001, 3 billion have been assigned. With the new types of services that we will have in the future, we will not only need IP addresses for personal computers and servers, but for mobile services based on GPRS (General Packet Radio System), the UMTS (Universal Mobile Telephone Service), high-speed access and “always on” mode, on-line electronics and communicating vehicles, home automation applications and sensor networks. A diminishing supply of IP numbers required a solution. Internet Protocol version 6 (IPv6) is the new version of its predecessor Internet Protocol version 4 (IPv4). Introduced by the IETF (Internet Engineering Task Force) on July 25, 1994 in RFC 1752 (Request for Comments), but draft standard didn’t come out until August 10, 1998 (http://playground.sun.com/pub/ipng/html/ipng-DS.txt).
Does everyone have to migrate?
Japan has mandated the migration to Ipv6 by 2005, while the European Union has set up an Ipv6 task force to promote the issue (http://www.wirelessweek.com/index.asp?layout=article&articleid=CA90251). The 3GPP effort has mandated IPv6 for the next generation of wireless networks. In its Release 2000 specification, the requirement for IPv6 to be built into the wireless IP multimedia subsystem started in 2002. This means that IP routers and servers for voice and data must support IPv6 and be able to assign IPv6 addresses to handheld devices (http://www.icr.a-star.edu.sg/ipv6/).
Most businesses have already been utilizing a work-around process called NAT (Network Address Translation RFC 1631). This is a method where an entire network can be mapped to a single IP address.
Ipv6 Mechanics
IPv6 is defined in a number of RFC documents primarily RFC 2460. IPv6 is also referred to as IP Next Generation (IPng). There are five categories of changes, as detailed in RFC 2460,...
