SEMINAR TOPICS INCLUDE: Visit gcn.com/ techessentials to register and for more event details After 20 years of talk and preparation, the deployment of IPv6 on Internet- connected networks appears to be slowly gaining traction, according to a recent survey by the Number Resource Organization (NRO). "We've entered a new phase" of real- world deployment, said John Curran, president and CEO of the American Registry for Internet Numbers, one of ve Regional Internet Registries respon- sible for distributing IP addresses, and which together make up the NRO. There are no dramatic shifts in the results of this year's IPv6 Deployment Survey, but they show steady progress in awareness of and adoption of the next generation of Internet Protocols. Deployment of IPv6 has become essential to the further growth of the Internet because of the depletion of un- assigned IPv4 addresses. Although the amount of IPv6 traf c is as yet small, with new allocations of large address blocks coming in the IPv6 space, net- works and content providers will have to enable the new protocols to accom- modate these users. The United States had the largest number of respondents from the 131 countries represented in the survey, with 215 out of 1,515. About 8 percent of respondents were from the government sector, a level of response that indicates a growing policy interest in adoption of the protocols. Although responses from govern- ments were not broken out in the sur- vey, "it is plain that government is at par or ahead" in deployment of IPv6, Curran said. "It has taken a leadership role." The biggest challenge cited in putting IPv6 into production is a lack of user demand, with technical issues second. This is illustrated by the small amount of IPv6 traf c on networks. Only a small sliver, about 3 percent, of 877 respon- dents with IPv6 in production say IPv6 traf c is equal to or greater than IPv4 traf c. Sixty-eight percent describe IPv6 traf c as insigni cant. Still, use of IPv6 by the customers of Internet service providers is growing. The percentage of ISPs with at least 0.5 percent of their customer base using IPv6 is about 30 percent, up from about 25 percent last year. • Agencies lead as IPv6 slowly begins real-world deployment BY WILLIAM JACKSON
