In January, the Number Resource Organization (NRO) announced that only 
ten percent of IPv4 address space remained unallocated. Since then, IANA 
allocations to the Regional Internet Registries (RIRs) has reduced the 
remaining pool of addresses to just over six percent, with an 
anticipated runout in 2011. With this in mind, we once again encourage 
all organizations to adopt IPv6.

ARIN has 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. In April of 2009, ARIN contacted, 
by certified letter, the CEOs of organizations that currently hold IPv4 
resources in its region to raise executive awareness of IPv4 depletion 
and IPv6 adoption. To keep up with ARIN’s current outreach activities 
and locations, please visit http://www.teamARIN.net/calendar.

Without IPv6, 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.

There are many ways to make your organization’s services available using 
IPv6, depending on your network setup and the services you have 
deployed. ARIN hosts an IPv6 Wiki to facilitate discussion and 
information sharing on IPv6 adoption topics and issues, which can be 
found at http://www.getipv6.info. If you have not already, now is the 
time to determine how your services will grow and be maintained using 
IPv6 addresses.
