ARIN Board Advises Internet Community on Migration to IPv6
The American Registry for Internet Numbers (ARIN) and the other Regional Internet Registries (RIRs) have distributed Internet Protocol version 6, IPv6, alongside IPv4 since 1999. To date, ARIN has issued both protocol versions in tandem and has not advocated one over the other. ARIN has closely monitored trends in demand and distribution for both protocol versions with the understanding that the IPv4 available resource pool would continue to diminish.
The available IPv4 resource pool has now been reduced to the point that ARIN is compelled to advise the Internet community that migration to IPv6 is necessary for any applications that require ongoing availability from ARIN of contiguous IP number resources. On 7 May 2007, the ARIN Board of Trustees passed the following resolution:
"Whereas, community access to Internet Protocol (IP) numbering resources has proved essential to the successful growth of the Internet; and,
Whereas, ongoing community access to Internet Protocol version 4 (IPv4) numbering resources can not be assured indefinitely; and,
Whereas, Internet Protocol version 6 (IPv6) numbering resources are available and suitable for many Internet applications,
Be it Resolved, that this Board of Trustees hereby advises the Internet community that migration to IPv6 numbering resources is necessary for any applications which require ongoing availability from ARIN of contiguous IP numbering resources; and,
Be it Ordered, that this Board of Trustees hereby directs ARIN staff to take any and all measures necessary to assure veracity of applications to ARIN for IPv4 numbering resources; and,
Be it Resolved, that this Board of Trustees hereby requests the ARIN Advisory Council to consider Internet Numbering Resource Policy changes advisable to encourage migration to IPv6 numbering resources where possible."
Implementation of this resolution will include both internal and external components. Internally, ARIN will review its resource request procedures and continue to provide policy experience reports to the Advisory Council. Externally, ARIN will send progress announcements to the ARIN community as well as the wider technical audience, government agencies, and media outlets. ARIN will produce new documentation, from basic introductory fact sheets to FAQs on how this resolution will affect users in the region. ARIN will focus on IPv6 in many of its general outreach activities, such as speaking engagements, trade shows, and technical community meetings.
