IPv4 time is running IPv6 address of the North American service providers Fengqiang

This year, the United States, Internet service providers to apply for an increasing number of IPv6 addresses, while IPv4 addresses are less and less, this situation is unprecedented, indicating that operators have begun to invest in the future, facing the modern history as the most painful of an economic recession, U.S. companies are finally beginning to march to the next generation IP protocol to prepare. too long, people are constantly predicts the Internet’s main communications protocol when they will upgrade from the current IPv4 standard to the next generation IPv6 This year for the changes in IP addresses that this upgrade will soon expected from North America began.

IPv4 uses 32-bit address, can support the Internet addresses of 43 million individual devices. While IPv6 uses 128-bit address, the device can support a large number of unthinkable: 2 128 th power! Prior to this, some people joked that this figure means that every grain of sand will have a IPv6 network address. In addition, compared with IPv4, and, IPv6 also offers built-in security and enhanced network management capabilities. but more importantly – is expected by 2012, IPv4 addresses space will be exhausted.

In 2009 the first 9 months, the United States Internet Numbers Authority Registry (ARIN) has been received from the operator, where 300 applications for IPv6 address space. By comparison, in 2008 and 2007, the year received only 250 applications.

“We see the demand for IPv6 address space a sudden rise in the rate of growth is very important,” ARIN President and CEO John Curran said, “We also see that the requirements of the IPv4 address space will probably have a slightly slower … … a rate of 10% or 20% of the rate of annual decline. “Curran said ARIN are beginning to see Comcast and Verizon Wireless for example, such a large ISP who are actively into IPv4-based network set up to use IPv6 built into the network migration in.

“ISP they are requesting IPv6 addresses to make their networks to enable IPv6, prepare for the future,” Curran said, “we provide enough for each ISP’s IPv6 address, able to support 4 billion network, each network has can have hundreds of millions of hosts. “Curran said that the economic recession did not hinder the operator’s interest in IPv6.

“IPv6 has not yet occurred ahead of schedule to resolve the problem (IPv4 address exhaustion). Accordingly, when you see we are very pleasantly surprised when demand increases, which means that they are planning for future business,” Curran said, “the current economic recession, and no significant inhibit demand for IPv6, because IPv6 is the ISP have the right choice. as we approach IPv4 address depletion may be only two years, but for an ISP, it’s enough to two years, the network deployed, two years to allow anyone Enjoy the make good planning. ”

ARIN will be held in Dearborn, Michigan this week’s policy meeting of the North American IPv6 addresses demand for a detailed description of the latest statistical data. ARIN will also be at the meeting on a number of the IPv4 address depletion and how to promote policy changes to accelerate the adoption of IPv6 discussions. These initiatives include:

* Allow ARIN to reduce the size of the IPv4 address space allocation, reduce the depletion of IPv4 addresses is getting closer and pressure.

* IPv6 address space will get easier the process of the abolition of operators will need to first prove that they have hundreds of clients limits.

* Allows operators to run multiple separate IPv6 network, without as interconnected as the community network.

• The need to include the ARIN registration bodies such as the regional average split recoverable IPv4 space to reconsider the current strategy.

In fact, China is also IPv6 in the construction of the situation is quite grim. As we all know, due to historical reasons, China’s IPv4 address allocation of the very few .2008 year in September, CNNIC (China Internet Network Information Center) said that under the current IPv4 address resources assigned speed left more than 830 days, when such measures are not taken in 2010, the new Internet users will not work online. but as of 2008, China’s IPv6 address of the number living in the world was only 16, with the world in terms of national gap is still large, only Germany, 1 / 330.

In April 2009, Internet Society of China announced that, following several years of efforts, China has built the world’s largest IPv6 next-generation backbone network, and the Chinese government is planning to further increase its efforts to promote commercial IPv6 trial .2009 6 month, led by Chinese companies for site and network service providers to start IPv6 service authentication. We look forward to China’s IPv6 early access to the fast lane!
