IPv6 is the Only Path to Continued Internet Growth

With 94.5% of IPv4 addresses already allocated and the remaining 5.5% expected to be allocated by mid-2011, a panel of industry experts, including John Curran, president and CEO of ARIN, explained that IPv6 is the only path to continued Internet growth at a recent NTIA IPv6 workshop.The panellists also agreed that IPv6 is necessary for all future efforts around cloud computing, smart grid, mobility, and the Internet of Things.To read the full news release from ARIN, with all findings and deliverables, see below.ARIN details key findings from NTIA IPv6 Workshop [news release]

Chantilly, VA, October 4, 2010 – The American Registry for Internet Numbers (ARIN), a nonprofit association that manages the distribution of IP addresses and other Internet number resources, announced today key findings from the NTIA IPv6 Workshop held on September 28, 2010. The workshop began with a panel discussion moderated by Aneesh Chopra, Chief Technology Officer for the United States, which brought together experts including John Curran, President and CEO of ARIN, to highlight the necessary steps American businesses must take to assure IPv6 adoption.With 94.5% of IPv4 addresses already allocated and the remaining 5.5% expected to be allocated by mid-2011, the panel of industry experts explained that IPv6 is the only path to continued Internet growth. The panelists also agreed that IPv6 is necessary for all future efforts around cloud computing, smart grid, mobility, and the Internet of Things.ARIN hopes that the workshop will encourage businesses that provide services over the Internet, for example via a website, to make the necessary IPv6 preparations sooner rather than later. Steps that businesses can take include:

  • Replacing any outdated equipment and software with IPv6-ready devices and applications
  • Encouraging hardware and application vendors to support IPv6, and specifically including IPv6 support in RFPs and contracts
  • Sending IT staff to IPv6 training seminars and encouraging them to read forums like the ARIN IPv6 Wiki
  • Talking to ISPs about getting IPv6 service or about tunneling IPv6 over IPv4

Other key outcomes from the NTIA industry panel:

  • Chopra called out three deliverables that industry experts should help create to provide clarity for the enterprise industry, and to help businesses with their IPv6 transition.
  • Create a template for enterprise board members to evaluate adoption risks and keep up-to-date on their organizations’ IPv6 adoption status
  • Create a template for engineers that includes the right questions to ask vendors and any training activities they should take part in
  • Create a transparency dashboard so both domestic and international enterprises and governments can see how the United States, as a whole, is progressing toward IPv6 adoption

Jason Livingood, Executive Director for Comcast highlighted some findings from Comcast’s recent IPv6 trials. Native IPv4 and IPv6 dual-stack networks have the best access and are ultimately less expensive to set up and operate.Following the industry panel, Chief Information Officer for the United States, Vivek Kundra, led a government panel detailing the U.S. Government’s commitment to the operational deployment and use of IPv6. Mr. Kundra also announced additional steps <www.cio.gov/Documents/IPv6MemoFINAL.pdf> government agencies must take to expedite the operational deployment and use of IPv6. These steps include:

  • Upgrade public/external facing servers and services (e.g. web, email, DNS, ISP services, etc) to operationally use native IPv6 by the end of FY 2012
  • Upgrade internal client applications that communicate with public Internet servers and supporting enterprise networks to operationally use native IPv6 by the end of FY 2014
  • Designate an IPv6 Transition Manager by October 30, 2010, to serve as the person responsible for leading the agency’s IPv6 transition activities, and liaison with the wider Federal IPv6 effort as necessary
  • Ensure agency procurements of networked IT comply with FAR requirements for use of the USGv6 Profile and Test Program for the completeness and quality of their IPv6 capabilities

“The good news is this part of the ecosystem is up and running. We have the protocol people need. We have the administrative infrastructure to issue IPv6 addresses,” added Curran. “I’ve been informing Internet backbone companies, content providers, enterprises, and governments that we’re going to be running out of IPv4 addresses for 15 years. It’s now taking those plans and realizing them promptly over the next 18 months that will be essential for success.”About the American Registry for Internet Numbers (ARIN)

IPv4 Address Pool Shrinks to a Perilous New Low Level

The number of IPv4 addresses remaining has shrunk to 6.25 per cent of the total address pool in June from what was already considered a low ten per cent of IPv4 addresses unallocated in January according to a statement on the ARIN website from their president and CEO John Curran.ARIN has used statistics from the Number Resource Organization (NRO) and notes that since January IANA allocations to the five Regional Internet Registries (RIRs – of which ARIN is one) has reduced the remaining pool of addresses to just over six percent of addresses, with an anticipated run out in 2011 although with IANA policy to automatically give one address space block to each of the registries when the address pool reaches a certain level, the free pool of addresses could be depleted overnight.ARIN has made an urgent plea to encourage all organisations to adopt IPv6. However please have been made for several years for organisation to adopt IPv6 and each one seems to fall on deaf ears!Demand for IPv4 addresses have plateaued in North America while growth is still strong in the Asian region. And it is this demand in Asia that saw in the first half of 2010, IANA allocate more IPv4 addresses to the registries than in all of 2009 according to a Network World report.ARIN note they have been allocating IPv6 addresses since 1999 and has been actively advocating the need to deploy IPv6. In 2007, the ARIN Board of Trustees resolved to educate and inform the Internet community regarding IPv4 depletion and the increasing need to adopt IPv6. This resolution became part of a larger IPv6 outreach campaign to encourage those currently running IPv4 to begin adopting IPv6. As part of their campaign, in April of 2009 ARIN contacted by certified letter the CEOs of organisations in North America that currently hold IPv4 resources in its region to raise executive awareness of IPv4 depletion and IPv6 adoption.Without IPv6, ARIN say the internet’s expansion and innovation could be limited. Delaying IPv6 deployment may strain the work of Internet operators, application developers, and end users everywhere. Furthermore, organizations whose business model is dependent on availability of IP addresses may find their growth limited without adopting production IPv6.For more information, ARIN host the IPv6 Wiki to facilitate discussion and information sharing on IPv6 adoption topics and issues at www.getipv6.info.

ARIN to Consider Looming IPv4 Shortage, IPv6 Transition

With less than 8% of available IPv4 addresses unallocated, ARIN will be holding a meeting next week to consider whether any policy changes are necessary for the transition to IPv6 to occur smoothly.

The meeting, to be held in Toronto, Canada, from April 18 to 21, will consider a number of draft policies and proposals. Some of the topics up for discussion by the Internet community are:

  • Simplifying IPv6 allocation criteria
  • Providing smaller blocks of IPv4 address space
  • Handling IPv4 requests once address space becomes limited
  • Changing the requirements for what information must be recorded in ARIN’s WHOIS database

“The Internet has become an irreplaceable part of how consumers and businesses communicate,” John Curran, president and CEO of ARIN, said in a statement.

“With less than 8% of IPv4 addresses still available, our mission is to consider any policy changes necessary for this transition to occur smoothly, and to continue discussions about this important issue. ARIN XXV will include important discussions on draft address allocation policy proposals, including several proposed changes that may affect IPv6 adoption.”

The transition to IPv6 is also being encouraged by the OECD who noted “IPv6 use was growing faster than continued IPv4 use, albeit from a low base. And several large-scale deployments are taking place or are planned.”

The report noted that “5.5% of networks on the Internet (1 800 networks) could handle IPv6 traffic by early 2010. IPv6 networks have grown faster than IPv4-only since mid-2007. Similarly, demand for IPv6 address blocks has grown faster than demand for IPv4 address blocks. Even more encouragingly, Internet infrastructure players seem to be actively readying for IPv6, with one out of five transit networks (i.e. networks that provide connections through themselves to other networks) handling IPv6. In practice, several indicators are closely correlated and point to the same countries as having the most IPv6 network services. These include Germany, the Netherlands, the United States, and the United Kingdom.”

However the report found “the number of potential users of IPv6 is quite high with over 90% of the installed base of operating systems being IPv6-capable, and roughly 25% of end users running an operating system that supports IPv6 by default in January 2010, such as Windows Vista or Mac OS X.”

But the report also found “actual IPv6 connectivity by users is very low. A one year experiment by Google estimated that just 0.25% of users had IPv6 connectivity (and chose IPv6 when given the choice) in September 2009, up from less than 0.2% one year before. After France, the top countries by percentage of native IPv6 capable users in September 2009 were China, Sweden, the Netherlands, the United States, and Japan.”

The report also noted that “only 1.45% of the top 1000 websites had an IPv6 website in January 2010, but this figure grew to 8% in March 2010 when Google websites were included. However, only 0.15% of the top 1 million websites had an IPv6 website in January 2010 (and just 0.16% in March 2010). A trend may be emerging whereby large websites are deploying IPv6 alongside IPv4, while the vast majority of smaller websites remain available only over IPv4.”

The report makes a number of recommendations, similar to those made in another report from 2008. “In May 2008, the OECD warned that Governments and business must tackle Internet address shortage together. In particular, governments and business needed to work together more effectively and urgently to meet the growing demand for Internet addresses and secure the future of the Internet economy by implementing IPv6. Not implementing IPv6, it warned, would impact the economic opportunities offered by the Internet with severe consequences in terms of stifled creativity and deployment of new services.”

“As the pool of unallocated IPv4 addresses dwindles, all stakeholders should anticipate the impacts of the transition period and plan accordingly to gather momentum for the deployment of IPv6 to decrease the pressure on IPv4. In particular, to create a policy environment conducive to the timely deployment of IPv6, governments should consider: i) Working with the private sector and other stakeholders to increase education and awareness and reduce bottlenecks; ii) Demonstrating government commitment to adoption of IPv6; and iii) Pursuing international co-operation and monitoring IPv6 deployment.”
