What is IP version 6?
The Internet Protocol provides the standard format for addressing, describing, and sending packets of data across the global Internet.
Version 4 of the Internet Protocol has been an amazing success for over twenty years, but available IPv4 addresses will probably be exhausted well within the next decade.
The familiar IPv4 format of 123.456.789.255 offers only four billion addresses, not even enough for the world's current population.
The Internet Engineering Task Force designed Internet Protocol version 6 to provide more addresses, with better security, mobility, and ease of configuration. It is written in hexadecimal, e.g. 12AB:0:0:CD30:123:4567:89AB:CDEF.
This odd format allows for 340 billion, billion, billion, billion unique IPv6 addresses - five million billion times the number of observable stars in the sky, and more than enough for all of the computers, networks, phones and people in the world!
Why bother with IPv6?
IPv6 will offer business and strategic benefits in trade, services, logistics, and defence.
Booming economies such as China and India are experiencing exploding demand for connectivity beyond the limits of IPv4: their growing Internet markets will be built on IPv6.
The Korean and Japanese govenments have already mandated large IPv6 deployment and education programs. The European Union has been supporting IPv6 pilot networks since 2000.
The US Defense Department and the Office of Management and Budget have set the looming deadline of June 2008 for their backbone networks to become IPv6-capable.
The major trading partners and defence allies of Australia have committed themselves to a future Internet based upon IPv6, and the implications are enormous.
Costs and benefits of IPv6?
New platforms trigger bursts of innovation, and IPv6 is no exception. Today what appears to be little more than an improvement in 'network plumbing', has incredible potential for the next generation of technology.
An IPv6 Economic Impact Assessment from RTI International estimated the cost of IPv6 deployment over a 25-year period in the U.S. would be around one billion dollars per year ... but the potential benefits were more than ten billion dollars per year.
Features such as mobility, billions of addresses, auto-configuration and better security protocols will drive innovation in Internet commerce, services and technology, especially for:
- Quad-play content - data, voice, video and wireless - information diversity and mobility
- Social interaction - email, voice, messaging, games, peer-to-peer, markets, flexible online communities
- Device networks - inventory logistics, building environment control, sensor networks, RFID systems, security monitoring
- Ubiquitous communication - the Internet via every medium, everywhere, for everyone!
IPv6 was designed to co-exist with IPv4, to be implemented in stages such as:
- Exploring pilot IPv6 projects on IPv4 networks
- Running separate IPv4 and IPv6 infrastructure
- Transitioning to dual-stack IPv4/IPv6 devices
- Moving to native IPv6 and phasing out IPv4
- Assess their requirements, risks and benefits
- Survey existing network infrastructure
- Educate technical staff professionally
- Resource network and security infrastructure
- Phase-in and test IPv6-capable devices
- Inform and set policies for general staff
- Monitor and maintain systems and procedures
However, moving successfully to IPv6 is only possible with strategic understanding in the boardroom, long-term planning by management, and professional resources for technical staff.
