IPv4 Address Pool Shrinks to a Perilous New Low Level
Posted in: Domain Names at 18/06/2010 21:39
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.
