January 27 Noon News, IPv4 address is about to run out of concern, Sina technology access to information shows that, although the international IPV4 address is expected to be allocated next month, but domestic operators, such as the longest IPv4 address can support 5-6 years, and IPv6 in the domestic development is still in the early stages.

It is reported that in the case of lack of IP address, operators will be forced to use the common address conversion mode, may cause the national information network infrastructure running inefficient, poor stability, can not be effectively managed. This could also lead to increased internet costs for users, limited access to existing Internet resources and restrictions on services.

Relevant experts pointed out that users generally use private address or dynamic address to communicate, to a certain extent, the impact of video on demand, network telephony, such as the full use of network services. In addition, private and dynamic IP address is easy to cause security problems, but also to purify the network environment has brought a considerable degree of management difficulties.

Detailed answers to questions about IPV4 depletion and IPV6 deployment are listed below, and are provided mainly by China Internet Network Information Center (CNNIC), million network and other institutions and enterprises. (Menghong)

IP Address exhaustion Interpretation:

Question: When will the IPV4 address be depleted?

Answer: The longest in the country can last six years.

According to data from Cnnic, as of January 24, 2011, the IANA (Internet Digital distribution Agency) address pool remaining 7 a IPV4 address (that is, 117 million), is expected to be allocated in February this year. By the end of December 2010, the number of IPV4 addresses held in China was 277 million.

China's IPV4 address has been applied through several major network operators and the China Internet Information Center. In our country has the IPV4 address, the operator still grasps some IPv4 to be able to use, according to the operator network and the business different situation, some operators hand's address can support the next 5-6 years, some can only support 1-2 years.

Question: IPv4 depletion of the industry impact geometry?

Solution: Network infrastructure operation inefficient, poor stability, can not be effectively managed

IPV4 Address resource depletion has a great impact on the development of Internet in China, now the internet is exploding, Chinese netizens are growing rapidly, the lack of IPV4 address will severely restrict the popularization of Internet in our country, it will also restrict new business, new application, and affect the security and stability of our network infrastructure.

Because the IPV4 address is about to run out, the network new business, new application development and scale of deployment will be limited, such as Internet users at the same time limited, users will not be able to fully use some of the public IP address of Internet services. In addition, the shortage of IP address resources and countries to accelerate the scramble to form a vicious circle, eventually become the bottleneck of industrial scale.

For the whole national information infrastructure, the use of address conversion is constrained by the lack of IPv4 address, which may result in inefficient operation and poor stability of the network infrastructure of national informatization, which can not be effectively managed.

Question: IPv4 depletion affect the user geometry?

Answer: Affect the full use of VOD, VoIP and other services.

For users, the IPV4 address resource is depleted, which may involve an increase in the cost of Internet access, because operators will take some countermeasures, which will bring some cost to the user to improve the Internet costs. For new network users, if the IPV4 address is not available, then access to existing Internet resources and services will be greatly limited.

Secondly, from the performance and stability of the network infrastructure, the lack of IP address may force people to use the private address or dynamic address to communicate, the address conversion device is easy to form the single point of fault and performance bottleneck of the network, resulting in inefficient operation and poor stability of the national network infrastructure. In addition, private addresses are not legal addresses, Can not appear in the public network, users will not be able to fully use some such as video-on-demand, Internet telephony, such as end-to-end Internet services.

In short, for China's ordinary netizens, if the operator does not have the IP address available for distribution can not develop new users, will affect the normal Internet users browsing, network application scale will be greatly restricted.

Question: What are the disadvantages of dynamic IP address?

Answer: The network information security problem mostly is the loophole that the address hides cannot be traced effectively.

From the perspective of information security, private and dynamic IP addresses can cause security problems, for example, network spam, network intrusion/attack (including Trojan horse), network deception, website fraud, malicious release of false information and other network information security problems are mostly drilling the address hidden can not be effectively traced loopholes, causing huge losses to society, Also to purify the network environment has brought a considerable degree of management difficulties.

In the face of DDoS (distributed denial of service) attacks, shared IP There will be a lot of innocent users being implicated and harmed as a result of an attack or an IP shield, and a service in which the IP is not available to other users because of a user sending a spam message that is blocked by the antispam (anti-spam) organization.

The user's application cannot be directly accessed or debugged over IP, with poor usability and flexibility. And this way is not conducive to SEO, non-independent IP general search engine unfriendly, too many domain names share an IP may be reduced to the right, not conducive to the natural rankings of the site.

Question: What are the advantages of IPV6?

Answer: More addresses, more security.

IPV6 address resources are Ipv4 8x1028 times, so that computers, peripherals, household appliances, communication tools and so on have a separate IP address, which will make the Internet really become a link between resources and configuration, can also be used as the basis for the realization of the network of things.

Another advantage of the IPV6 protocol is security, IPV6 header is fixed to 8 necessary fields, from the technical level to eliminate the current through the imitation of the source address of the possibility of implementing DDoS attacks, this is the most essential solution for DDoS attacks.

Question: What progress has the transition to IPv6 been?

Solution: The industrial chain is imperfect, still in the formative stage.

By the end of December 2010, the number of IPV6 addresses in China was 401 Yuan/32 (2 of 96 times), accounting for 0.29% of the total allocated IPv6 in the world. Compared with IPV4 network, the development of IPV6 network in our country is still in the early stage, and has not yet entered the stage of extensive deployment and implementation.

At present, the strategy of IPV4 to IPV6 in our country faces several challenges: first, the IPv6 industry chain is not perfect, but also in the forming stage of industrial development; IPV6 network deployment, China's network operators have basically completed the backbone of the network IPV6 transformation process, backbone network equipment basic Support ipv4/ IPV6 Double stack.

However, the development of IPV6 network in our country is concentrated on the backbone network, extending to the metropolitan area Network and the Edge network, it is difficult to provide an effective platform for the development of IPV6 characteristic business and the scale commercial, and the corresponding IPV6 terminals are relatively few. Because of the large number of private addresses used by operators, it is not positive for the development of IPV6 users, which directly affects the IPV6 investment of other industries; there is no unified national address management distribution mechanism.

In addition to technology, IPV4 and IPV6 interconnection is a big problem, the current Internet applications are still on the IPV4 network, if not a good solution to the IPV4 and IPv6 interoperability problems, IPV6 will become an island, can not be substantial large-scale promotion.
