The old address pool is almost exhausted, and the development of IPv6 is imminent.
IPv6 is the abbreviation of "Internet Protocol Version 6". It is a next-generation Internet core protocol designed by the Internet Standardization Organization IETF to replace the current version of IPv4. It has mature standards for transition, routing, network management, transmission, security, etc. .
Recently, the next-generation Internet National Engineering Center officially announced the IPv6 public DNS: 240c::6666. By providing free public DNS services with excellent performance, we will create a safe, stable, high-speed and intelligent online experience for the majority of IPv6 Internet users, and help China's "Promoting Internet Protocol Version 6 (IPv6) Scale Deployment Action Plan" fully implemented. At the same time, the Engineering Center also launched the global IPv6 public DNS promotion plan in conjunction with the IPv6 Forum to provide better online resolution services for users around the world.
The current IPv6 network has become a leading area for countries to promote the new science and technology industry revolution and reshape the country's long-term competitiveness. All countries in the world have accelerated the pace of transition to IPv6. At the same time, the number of IPv6 users has also experienced explosive growth in the past two years, and the IPv6 development situation that has been quiet for many years has been significantly improved. The launch of the IPv6 Action Plan will undoubtedly reinforce the already-promoted IPv6 industry and accelerate the overall deployment of the next generation Internet in China.
As an important part of the network infrastructure, the Domain Name System (DNS) has been frequently attacked for the past 30 years due to its "speciality". Top-level domain failures, DNS hijacking, large-scale DNS attacks, etc. have occurred, giving the global Internet industry. Has a serious impact. At present, most of the public DNS that enhances the user experience and guarantees network security is only for IPv4, which is one of the problems that IPv6 users continue to criticize. To fully support the development of IPv6, the next-generation Internet Engineering Center relies on the self-developed high-performance IPv6 DNS system to provide DNS services to the public free of charge. The preferred DNS: 240c::6666, alternate DNS: 240c::6644.
The Next Generation Internet National Engineering Center is the only national-level engineering research center in China's next-generation Internet field. Over the years, it has been committed to the research and promotion of key technologies and applications of IPv6 next-generation Internet. The IPv6 public DNS launched this time will undoubtedly provide an excellent choice for IPv6 users around the world to optimize the Internet experience. Its precise, fast, secure and stable DNS64 features will fully guarantee the efficiency and stability of the IPv6 network.
According to reports, the engineering center deploys recursive nodes in many regions of the world such as Beijing, Guangzhou, Lanzhou, Wuhan, Chicago, Fremont, London, and Frankfurt. Based on the IPv6 BGP Anycast mode, users can access the nearest access, so that the access delay of the domain name resolved to the root server is significantly reduced, and the speed can be guaranteed. Not only that, IPv6 public DNS will reduce the recursive process by actively synchronizing com/net domain names, cache hotspot domain names, etc., to achieve maximum response.
In terms of security, the IPv6 public DNS supports the rate limit of single-IP resolution. The security rate limit can effectively block malicious attacks. The user's access security will be protected in real time. At the same time, IPv6 public DNS supports DNSSEC security resolution verification. Users do not have any hijacking during the access process, and there will be no malicious jumps or mandatory advertisements.
At the same time, in order to facilitate the practical needs of IPv6 users to access IPv4 related services, IPv6 public DNS specially introduces DNS64 resolution service, that is, the resolution system can also respond to pure IPv6 users' request for parsing pure IPv4 network resources, which also avoids to some extent. The content brought by the transition period of IPv4 to IPv6 has not been completely upgraded and upgraded.
Liu Dong, director of the next-generation Internet National Engineering Center, said that “early development and rapid development of IPv6 networks are key measures for China to strive for global Internet initiative. The construction and upgrading of public infrastructure is a prerequisite for large-scale deployment of IPv6. The vision and efforts of the Engineering Center for many years. This IPv6 public DNS is a global free service, which not only provides a faster and safer choice for IPv6 users worldwide, but also hopes to fully promote IPv6 next-generation Internet deployment in China. Play a facilitating role."
