Deploying IPv6: The Time Is Now

On 3 February 2011, the central pool of available IPv4 addresses managed by the Internet Assigned Numbers Authority (IANA) was depleted when each Regional Internet Registry (RIR) received its last /8 or 16,777,216 addresses.The five RIRs (AFRINIC, APNIC, ARIN, LACNIC and the RIPE NCC) will continue to allocate IPv4 address space to their members in accordance with their community-based regional policies until their pools of available IPv4 addresses are depleted. It is difficult to predict when the RIRs will run out of IPv4 addresses.

The deployment of IPv6, a newer protocol that offers many more addresses, is imperative to the long-term growth, security and stability of the Internet.

The NRO, on behalf of the five Regional Internet Registries (RIRs), is calling on all stakeholders to make the deployment of IPv6 a priority. The NRO’s efforts include:

  • IPv6 address allocation, management, and deployment measurement
  • Research, education, and information distribution
  • Community outreach and liaison
  • Representation in Internet governance forums

The resources listed on this site will assist your organization in making decisions and planning your IPv6 implementation strategy.

Take the next IPv6 stepThe IPv4 Internet will continue to operate, but the lack of available IPv4 addresses may affect network growth. The adoption of IPv6 offers a solution.

Global IPv6 Deployment Monitoring Survey

Since 2010, the NRO has worked closely with TNO and GNKS Consult to carry out an annual survey on IPv6 deployment. Following on from earlier region-specific surveys carried out by ARIN/CAIDA, the RIPE NCC and European Commission, and APNIC, the survey results provide a better understanding of IPv6 deployment over time, and the challenges that still need to be overcome to ensure the global adoption of IPv6.
