The IPV9 technology (or the so-called Decimal network) that used to defend China's Internet sovereignty a few years ago has now been muted, and its inventor Xia Jianping, the decimal network standard Working Group and its academic team have been refusing to disclose technical details about IPV9 on the basis of "trade secrets", But recently a netizen named Yx9fun to debunk the mysteries behind IPv9.

Digital Domain name similar to DNS hijacking

In the original propaganda, IPv9 's biggest feature is the use of decimal number for the URL code, that is, users can enter a simple number of domain names such as "12345", to replace similar "www.abc.com" such a domain name.

Yx9fun explains in detail the implementation of the IPV9. First, from the "Decimal Network standard workgroup" official online download a plug-in, after installation, the computer system in the registry changed, the original DNS server (responsible for the domain name resolution to IP address) was changed to a strange address 61.152.248.222, this is actually a DNS server provided by the workgroup. If you are logging on to a site that has already started using a digital domain name, such as "12345", then after entering http://12345 in the browser, The computer will connect to 61.152 248.222, with the existing DNS protocol to resolve 12345, in fact, or 12345 to the actual site to resolve the IP address, and then the computer based on this IP address and then log on to the site.

Yx9fun said that the whole process is similar to the common DNS hijacking, by IPV9 directly modify the user DNS server address, so that users unknowingly directly using IPV9 DNS server to resolve. Yx9fun stressed, "this approach is similar to the previous 3721 of the network real name, in the address bar input Chinese names, you can open the corresponding Web site, the same need to install plug-ins to achieve." ”

IPV9 address is just a calculation game

In fact, the so-called IPV9 address does not need to apply to the Decimal network standard workgroup, it is actually a simple calculation process. Now commonly used IP address (IPv4 address), itself is a 4-bit 256-digit number. For example, 64.233.189.104 is Google's IP address, the "104+256x189+256x256x233+256x256x256x64" method can be added to a number 1089060200, after installing Plug-ins, Enter http://1089060200 directly in the browser to open Google.

According to Yx9fun's tip, the reporter to the It Times web site's IP address also tested, according to the formula conversion, got 3729045999 this "IPv9 address", installed in the official website provided by the plugin, directly in the browser after the input http://3729045999, Then normal opened the home page of this newspaper website.

The ultimate aim is to profit

As mentioned earlier, the IT Times IPv9 address 3729045999 is not easy to remember, if you want to get a more memorable, similar to 1234567 IPv9 Digital domain name, you must to the decimal network (China) Information Center (IPv9 specific operators) to apply for payment.

On the "Decimal Network Standards Working Group" official web site, the reporter found a "Dnic Address distribution Alliance cost statement" document, the article mentioned some principle of payment: "The new application to become a member of the Union, the unit must pay 20,000 yuan to open the account fee The union member IPv9 the single application address quantity according to 8000 yuan each 17 address to collect, less than 17 presses 17 to calculate, the union member according to Dnic assigns as number (namely the so-called Liang number) quantity to pay as the number annual fee: According to 10000 yuan/year each as number collects. "And so on.

Yx9fun to this point of view, "Decimal Network standard Working Group" is to do similar "QQ beautiful number" business, selling the decimal domain name, and then profit.

What is the

IPv9? After the reporter repeatedly search, finally found the term first appeared in the document. On the official website of the IETF (Internet Engineering Task Force, the Standardization organization responsible for the development and promotion of Internet standards), the journalist found a document with an RFC number of 1606, the first mention of IPV9. File title for "The History of using IP version 9", there is a lot of parody under the seemingly-honest headlines, such as the fact that the main reason for Internet IP address shortages is "the discovery of intelligent life in other solar systems and the hyper-light stack", "to inject IPv9 addressable components into the bloodstream", There are sci-fi phrases like "parallel universe", "Nano Robot", "quark-quark transistor". It is worth noting that the release date of the document is April 1, 1994, just April Fool's Day.
