Domain Name is also called URL or web address, which means logging on to the Internet Website Design A set of alphanumeric strings at the location of the user's host, which is a unique identifier for searching the location of a website on the Internet. In the Internet, every computer will have a unique identifier, which is the IP address used to distinguish thousands of computers connected to the Internet. Each IP address is composed of four numbers less than 256, and the numbers are separated by dots. For example, 123.123.123.123 represents a 1P address. It is easy to see that the IP address is difficult to remember when used, so a character address corresponding to the digital IP address on the network appears, which is called the domain name. A domain name can only correspond to one computer host. The domain name is unique.
1. The importance of city name Technically, the city name is just a method to solve the address correspondence problem in the Internet. It can be said that it is just a technical term. However, since the Internet has become the Internet of people all over the world, the city name has naturally become a social science term. From the perspective of social science, domain names have become an integral part of Internet culture. From the perspective of the business community, domain names have been called "online trademarks of enterprises". No enterprise does not attach importance to the logo of its own products - trademarks, so the importance and value of domain names have been recognized by enterprises all over the world. The online "index" function of the city name can attract business opportunities for enterprises on the Internet and extend the brand price. Good domain names can impress consumers deeply. In the new economic era, if any enterprise wants to enter the Internet, it can not cross the basic stage of having a city name, so its important value of existence is beyond doubt.
2. Composition of city name The domain name is composed of two or more words, separated by a dot in the middle, and the words on the right are called top-level city names. The general format is as follows: host name, network name, organization name, top-level city name. For example, the domain name of Tsinghua University's website is www.tsinghua.edu.cn, which means that the domain name is from low to high level from left to right. www represents the World Wide Web, as the lowest level city name; Tsinghua is the english name of tsinghua. it is the third level domain name: edu refers to the secondary city name of educational institutions. Cn stands for the top city name of the country. Different city names at any level are regarded as different domain names. For example, www.abc.com.www.abc.net and bc.com.cn are three different city names, probably belonging to three unrelated websites.
The two letter top-level city names, such as (China),. us (the United States), de (Germany) and IP (Japan), are called country code top-level domain names (ccTLDs). Among them,. cn is the exclusive top city name in China. Its registration is managed by CNNIC (China Internet Network Information Center), and the secondary domain name ending in. cn is referred to as the domestic domain name for short. The following are some common Chinese top-level domain names: ac.cn - applicable to scientific research institutions; Com.cn - applicable to industrial, commercial, financial and other enterprises; Edu.cn - applicable to educational institutions: net.cn - applicable to the information center of Internet and access network; Org.cn - Applicable to various non-profit organizations. In 2009, the registration of com.cn accounted for 26.74% of the total number of city names.
At present, there are 34 administrative regions in China, which are suitable for all provinces, autonomous regions and municipalities directly under the Central Government, including bj Beijing, sh Shanghai, tj-R Tianjin, cq Chongqing, he Hebei, nm Inner Mongolia Langgu, In Liaoning, ji Jilin, hl-M Heilongjiang, js Jiangsu, zJ Zhejiang, ah Anhui, fj Fujian, jx Jiangxi, sd Shandong Ha Hainan Province, hb Hubei Province, hn Hunan Province, gd Guangdong Province, rL Guangxi Zhuang Autonomous Region, sc Sichuan Province, gz Guizhou Province, yn Yunnan Province, xz Tibet Autonomous Region, sn Shaanxi Province, qh Qinghai Province, iL Ningxia Hui Autonomous Region, xj Xinjiang Uygur Autonomous Region, tw Taiwan, hk Hong Kong, a Macao.
3. Naming rules of city names Since domain names at all levels on the Internet are managed by different institutions, the ways in which institutions manage city names and the rules for naming domain names are also different. However, the naming of city names also has some common rules, mainly including the following: (1) Domain names can only contain the following characters: 26 English letters, 0, 1, 2, 3 4. 5. 6. 7. 8.9 Ten numbers. (2) The combination rules of characters in domain names: in city names, the case of English letters is not distinguished. There are certain restrictions on the length of a domain name. (3) The naming rules of city names under cn are: follow all the common rules of city names; The early cn domain name can only register the third level domain name. Since December 2002, CNNIC has opened the secondary domain name registration under the domestic cn domain name, which can be directly registered under. cn. (4) The following names shall not be used or restricted: the registration of domain names containing "CHINA", "CHINA", "CN", "NATIONAL", etc. shall be formally approved by the relevant national departments (referring to units above ministerial level); The names of other countries or regions, foreign geographical names, and international organizations that are known to the public shall not be used. The full name or abbreviation of the name of an administrative division at or above the county level (including the county level) shall be formally approved by the relevant people's government at or above the county level (including the county level); The trade name or the common name of the commodity shall not be used; The enterprise name or trademark name that others have registered in China shall not be used; Names that are detrimental to the national, social or public interests shall not be used. With the official approval of relevant national departments (units at or above the ministerial level) and the official approval of relevant people's governments at or above the county level (including the county level), the relevant institutions shall issue written documents to consent to the registration of xxx domain names by xxxx units. If you want to apply for the beijing.com.cn domain name, you should provide the approval of the Beijing Municipal People's Government.
Since individual web browsers, e-mail programs or online applications may not support city names with more than 26 characters, it is recommended that the domain name should not exceed 26 characters. However, most web browsers still support. com. net and. org city names with more than 26 characters. At present, only. com. net, org. cc Chinese network and company domain names support Chinese domain names. The Chinese city name must have at least two Chinese characters and at most 15 Chinese characters. The Chinese city name can contain English characters and numbers. Other domain names should not be in Chinese. Since domain names are regarded as online trademarks of enterprises, it is crucial to register a good domain name. A good domain name is often consistent with the following information of the enterprise: the Chinese and English abbreviations of the enterprise name; The registered trademark of the enterprise's products; The content in Chinese and English consistent with the corporate advertising language, but it should not exceed 20 characters; More interesting or easy to remember nouns, such as kaixin 163, etc.
4. Domain name registration Chinese enterprise websites can register domain names through CNNIC, or apply for authorized agents through CNNIC domain name registration. Now many institutions and companies have city name registration services, such as China Wanwang（ ）, www.sale-domainname. com, Dnsl63 (www.dnsl63. com), etc. The general process of registering a domain name at CNNIC is to fill in the registration application form and submit it to the domain name registration system to check the legitimacy and duplication of the domain name; Mail the required application materials, review the registration materials, pay the domain name registration fees, and issue the "domain name registration certificate" and invoice.
Early city name application is very easy, and individuals can apply without very detailed written information. However, since December 14, 2009, in order to improve the authenticity, accuracy and integrity of domain name registration information, and further strengthen the review of domain name registration information, CNNIC has added new provisions on domain name applications: users should submit written application materials while submitting online domain name registration applications to domain name registration services. The application materials include the domain name registration application form (original) stamped with the official seal, the business license of the enterprise or the organization code certificate (copy and the ID card of the registered contact person (copy)). The domain name registration service agency shall carefully review the written application materials submitted by the user, submit the written application materials to CNNIC by fax or e-mail after passing the review, and retain the written application materials. Within 5 days from the date of submitting the online application for the domain name, CNNIC did not receive the written application materials or the domain name application materials did not meet the requirements. The domain name will be unregistered. The introduction of this new policy means that individual users cannot apply for city names later.
5. DNS and VDNS Domain Name Server (DNS) is used to translate domain names into 1P addresses recognized by computers. For example, if someone wants to visit sohu's website (www.sohu. com) DNS translates the domain name into IP address 61.135.132.3. This makes it easy for computers to find the website server of the domain name owner.
VDNS (Visual Domain Name Server) is a new generation domain name and network management system with all functions of DNS system and complete visual operation. VDNS domain name management system is the world's leading domain name management system with the most advanced technology in China. On VDNS, you can create a sub website with the same name while adding a secondary domain name. You can also easily use the visual interface to complete all DNS operations such as URL forwarding, host A records, pan domain CNAME records, MX mail records, and IP pointing control. The meaning of these operations is that the secondary domain name is a relative concept. This is relative to the parent domain name. Domain names have multiple levels. The middle is separated by dots. For example, a company's top-level domain name ends with com. All domains ending with com are its sub domains. For example, www.sohu.com is the sub domain of sohu.com, and sohu.com is the sub domain URL forwarding of com. The so-called URL forwarding is to guide users accessing the current domain name to another specified network address through the special settings of the expander. For example, URL forwarding allows users to access //www.abc.com Automatic steering access httv://www.cde.com.A Record (IP pointing): A (Address) record is used to specify the IP address record corresponding to the host name (or domain name). Users can point the website server under the domain name to their own Web server, and can also set the secondary city name of the domain name. MX record: used to locate the mail server, which is determined by the address suffix of the recipient when the email system sends mail. For example, when the recipient is“ [email protected] ”The system will resolve MX records in DNS for "mydomain. com". If an MX record exists, the system will forward the mail to the mail server corresponding to the MX according to the priority of the MX record. Domain name resolution: for example, the city name is. bc.com, and all mail.abc.com under it are resolved to the same IP address. For example, mail.abc.com will automatically resolve to the same IP address as. bc.com, and the displayed page will be the same as abc.com.
In addition to visually completing all DNS functions, the VDNS system also has an enhanced APACHE synchronization function. In other words, each sub domain name has the same powerful and complete core function as the main city name of www, which greatly increases the flexibility of the domain name.
