'No danger' of Internet-address shortage

NEWS

The idea that there is an Internet-address shortage looming in Asia or any part of the world is "misinformation", according to a senior executive at the body responsible for distributing and registering Internet-address resources in the Asia Pacific region. Paul Wilson, director general of APNIC (Asia Pacific Network Information Centre) denies the shortage, saying that it will take one or even two decades before the current address system runs out. "The source of the rumour has been one I've been tackling for the last five years, since I started in this position at APNIC. There are a number of reasons why people have this perception," he said. APNIC is one of four regional Internet registries currently operating in the world. It provides allocation and registration services which support the operation of the Internet globally. The registry gets blocks of addresses from Internet Assigned Numbers Authority, or IANA in the US, before allocating them to Asia Pacific ISPs and other bodies who ask for them. Some industry experts have predicted that IP (Internet protocol) addresses will run out in as little as two years as more users connect. The experts also point to the historical imbalance in the way addresses had been issued, with the US grabbing the lion's share, leaving little for the burgeoning Internet masses of China. The sums just don't add up, said Wilson. He said that around five blocks of "slash eight" or /8 addresses are consumed worldwide each year. Each block allows for 16 million host addresses. There are 100 blocks still available in the current IPv4 (IP version 4) system -- enough for 20 years, perhaps fewer when 3G (third-generation) phones take off, but certainly more than the two years predicted by doomsayers, he said. Wilson cites several reasons for the birth of the myth of the IP address shortage and the related idea that Asia is a latecomer to the IP address buffet. "There is lingering perception that maybe APNIC has been difficult to get addresses from in the past, and people will look simply look at the number of addresses allocated in different parts of the world and conclude that somehow things are different in the Asia Pacific. Historically they were different, but in today's world they are not," he said. Today, any organisation applying for addresses plays by the same rules, regardless of which country it is from, he said. "The blocks are allocated as they are required. So we don't have a set of addresses earmarked for the Asia Pacific. There is no pre-allocation for the region which can run out. When addresses are not available, there will be no more addresses left for the whole world," he said. There are several good reasons to adopt IPv6 worldwide, he said, but he also hoped that there would be less lobbying from parties with a vested interest in pushing rapid adoption. He warned of the adverse impact that could occur if panicked companies spent large sums on IPv6 networking hardware. "The danger of doing that if you promote that IP addresses are going to run out in a few years, then two or three years will pass, there will be no address shortage then what people will think about it?" he said. However, he added that in the last two years, due to the efforts of APNIC and other bodies, such messages of doom have grown fainter. In the last few years, the governments of Korea, China and Japan have been strong supporters of IPv6, their efforts strongly backed by domestic network equipment manufacturers and bodies such as the IPv6 Forum. Equipment makers naturally want ISPs and enterprises to spend money to upgrade to IPv6-compatible products, while Asian governments have felt the new numbering system, with its hugely expanded address space, gave them more room to manoeuver. Japan has a government-imposed deadline to upgrade its information technology sectors to run on IPv6 by 2005. The mandate is expected to stimulate network upgrades and application development. The US Department of Defense said it will move to IPv6 by 2008. Department acquisitions taking place after October of this year must be IPv6-compatible in order to help the military gear up for the transition. IPv6 promises both end-to-end security and quality of service, which aims to make sure packets traveling over the network arrive at their intended destination.
