Introduction:

==========What is a domain name? Domain name classification and meaning ============

Domain names with different suffixes have different meanings. Now the most popular domain name categories can be divided into international domain names and domestic domain names. The main difference lies in the way domain names are divided and the management organizations. To explain what an international domain name is and what a domestic domain name is, we must start with the domain name system. There are currently three types of top-level domain names in the domain name system on the Internet: category top-level domain names, geographical top-level domain names, and new top-level domain names. They are introduced as follows:

The first category is the category top-level domain name. There are 7 of them, which are now commonly referred to as international domain names. Since the Internet originally originated in the United States, the earliest domain names did not have country identification. People divided them into several major categories according to their uses, and they ended with different suffixes: .com (for commercial companies); .net ( for network services); .org (for organizing associations, etc.); .gov (for government departments); .edu (for educational institutions); .mil (for military fields); .int (for international organizations) ). The initial domain name system was mainly used by the United States. Therefore, American companies, institutions, government departments, etc. used "international domain names". As the Internet developed around the world, .edu, .gov, and .mil were generally only used by the United States. In addition to the special domain names, the other three commonly used domain names, .com, .org, and .net, have become common around the world. Therefore, these domain names are often called "international domain names" and are still used by countries around the world.

The second category is the geographical top-level domain name, which has 243 country and region codes. For example, .CN represents China and .UK represents the United Kingdom (for details, see the global country/region top-level geographical domain name suffix). In this way, domain names with the .CN suffix are accordingly called "domestic domain names".

Similar to the suffix naming of international domain names, there are also second-level domains with different meanings under the .cn top-level domain name, which mainly include category domains and administrative areas. This is what is commonly referred to as the second-level domain name: you can Third-level domain names are registered under second-level domains such as .com.cn or .net.cn. Third-level domain names can be divided into two categories: category domain names and administrative domain names.

Category domain names are domain names divided according to the nature of the applicant organization, including:

AC scientific research institutions

COM industrial, commercial, financial and other enterprises

EDU Educational Institution

GOV Government Department

NET Internet, Access Network Information Center (NIC) and Operations Center (NOC)

ORG various non-profit organizations

Administrative division domain names are divided according to various administrative divisions in China, and their division standards are based on the national standards issued by the former State Bureau of Technical Supervision, including "administrative divisions" There are 34 domain names, applicable to all provinces, autonomous regions, and municipalities in my country. For example, organizations in Beijing can choose a domain name such as cnnic.bj.cn.

The administrative region names of China’s 34 top-level domain names are:

BJ-Beijing; SH-Shanghai; TJ-Tianjin;

CQ-Chongqing City; HE-Hebei Province; SX-Shanxi Province;

NM-Inner Mongolia Autonomous Region; LN-Liaoning Province; JL-Jilin Province;

HL-Heilongjiang Province; JS-Jiangsu Province ; ZJ-Zhejiang Province;

AH-Anhui Province; FJ-Fujian Province; JX-Jiangxi Province;

SD-Shandong Province; HA-Henan Province; HB-Hubei Province;

HN-Hunan Province; GD-Guangdong Province; GX-Guangxi Zhuang Autonomous Region;

HI-Hainan Province; SC-Sichuan Province; GZ-Guizhou Province;

< p>YN-Yunnan Province; XZ-Tibet Autonomous Region; SN-Shaanxi Province;

GS-Gansu Province; QH-Qinghai Province; Uyghur Autonomous Region;

TW-Taiwan; HK-Hong Kong; MO-Macau.

In addition, starting from December 2002, CNNIC opened the registration of second-level domain names under the domestic .cn domain name. Domain names can be registered directly under .CN. For example, the domestic domain name registered by Times Marketing is: emarketer .cn.

The third type of top-level domain name, also known as the "new top-level domain name", is an international top-level domain name that ICANN decided to use in November 2000 based on the development needs of the Internet. It is also the international top-level domain name that has been used since 2001. Contains 7 categories: biz, info, name, pro, aero, coop, museum. The first 4 are unrestricted domains, and the last 3 are restricted domains. For example, aero needs to be registered as an aviation company, museum needs to be a museum, and coop needs to be registered as a collective enterprise (non-investor control, no need to maximize profits). The meanings and registration management organizations of these seven top-level domain names are as follows:

.aero, dedicated to the air transport industry, and is responsible for the Belgian International Aviation Telecommunications Technology Association (SITA);

.biz, A general domain name that can replace .com, the supervision agency is JVTeam;

.coop, dedicated to commercial cooperatives, is managed by the National Cooperative Business Association (NCBA) in Washington;

. info, a general domain name that can replace .net, is managed by Afilias, a joint venture of 19 Internet domain name registration companies;

.museum, dedicated to museums, is supervised by the Museum Domain Name Management Association (MDMA);

.name is a dedicated domain name for personal websites, and is managed by the UK's "GlobeName Registry";

.pro is dedicated to professionals such as doctors and lawyers, and the supervisory agency is a company in Dublin, Ireland. Internet domain name company "Professional Registration" (RegistryPro).

Background information on why ICANN wants to add 7 new domains:

Since the emergence of the international Internet in the 1980s, .com, .net, and .org have always been important to merchants and consumers. The three most popular gTLDs. In particular, the .com domain name accounts for more than 80% of generic top-level domains. For many years, NSI has had a monopoly on the registration and management of these three domains. In 1999, ICANN and the US Department of Commerce terminated this monopoly and introduced a competition mechanism at the REGISTRAR level. However, competition at the REGISTRY level is still not enough, resulting in the DNS system not improving significantly over the years. The REGISTRY of the new seven top-level domains was also selected in November 2000. Except for NSI having a small stake in the INFO domain REGISTRY, it has nothing to do with other major new domain REGISTRY. In this way, the launch of new top-level domains will introduce a competition mechanism in the REGISTRY industry. The new REGISTRY has improvements in terms of technology and operational mechanisms, such as: changing today’s situation where WHOIS is scattered in various REGISGTRARs and implementing the same WHOIS; domain name information (zone file) and WHOIS query are updated globally in 5 minutes. Previously, the .COM domain It takes 24 to 48 hours; higher system redundancy, security and authentication rigor. Seemingly recognizing the serious challenges posed by the new domain, the operator of the .com domain, Verisign Global Registry Service (which merged with NSI in 2000), submitted a new contract to ICANN (the new contract was officially approved by ICANN on April 2, 2001 ), proactively proposed to invest 200 million US dollars in the next few years to strengthen the infrastructure construction under the .COM domain.

After reading these introductions about top-level domain names and domestic domain name suffixes, we can find that many domain name resources can be used, but for commercial companies, so far, the most common domain name is still .com , domestic enterprises or foreign enterprises with domestic operations generally register the .com.cn domain name at the same time. Since the development and registration of the .cn second-level domain name, domestic websites seem to prefer using the .cn domain name.

Domain name is the link between the enterprise and the Internet website. It has an important identification function like a brand and trademark. It is the "key" for visitors to access the enterprise website, and is the symbol of the enterprise's existence on the Internet. It is responsible for It serves the dual functions of marking the site and guiding the corporate site.

Domain name plays an important role in the e-commerce development of enterprises. It is known as the "global trademark" in the Internet era. A good domain name will greatly increase the visibility of the enterprise on the Internet. Therefore, it is very important for enterprises to choose a good domain name.

================Principles for domain name selection====================

When selecting a domain name, you must first follow two basic principles.

1. The domain name should be concise, easy to remember and easy to input.

This is the most important factor in judging the quality of a domain name. A good domain name should be short, easy to pronounce, easy to remember, and easy to remember at a glance. It should also be clear in pronunciation and will not cause spelling errors. In addition, homonyms should be avoided when selecting domain names.

2. The domain name must have certain connotations and meanings

Using words or phrases with certain meanings and connotations as domain names will not only have good memorability, but also help achieve the company's marketing goals. For example, the name of the company, product name, trademark name, brand name, etc. are all good choices, so that the company's online marketing goals and non-network marketing goals can be consistent.

Techniques for domain name selection

1. Use the Chinese pinyin of the company name as the domain name

This is a better way to choose a domain name for the company. In fact, most domestic companies choose domain names this way. For example, the domain name of Hongta Group is hongta.com, the domain name of Xinfei Electric is xinfei.com, the domain name of Haier Group is haier.com, the domain name of Sichuan Changhong Group is changhong.com, and the domain name of Huawei Technologies Co., Ltd. is huawei.com . Such a domain name helps to increase the visibility of the company's online brand. Even if the company does not make any publicity, the domain name of its online site can easily be thought of.

2. Use the English name corresponding to the company name as the domain name

This is also a way for many domestic companies to choose domain names. Such domain names are particularly suitable for some industries related to computers, networks and communications. For example, the domain name of Great Wall Computer Company is greatwall.com.cn, the domain name of China Telecom is chinatelecom.com.cn, and the domain name of China Mobile is chinamobile.com.

3. Use the abbreviation of the company name as the domain name

Some companies have relatively long names. It would be too cumbersome and difficult to remember if you use Chinese pinyin or the corresponding English name as the domain name. Therefore, it is a good idea to use the abbreviation of the business name as the domain name. There are two methods of abbreviation: one is the Chinese Pinyin abbreviation, and the other is the English abbreviation. For example, the domain name of Guangdong BBK Electronics Industry Co., Ltd. is gdbbk.com, the domain name of Luzhou Laojiao Group is lzlj.com.cn, the domain name of China E-Commerce Network is chinaeb.com.cn, and the domain name of Computer World is ccw.com. cn.

4． Use the homophonic form of Chinese Pinyin to register domain names for companies

In reality, there are not a few companies that use this method. For example, the domain name of Midea Group is midea.com.cn, the domain name of Konka Group is konka.com.cn, the domain name of Gree Group is gree.com, and Sina uses sina.com.cn as its domain name.

5. Register a domain name for the enterprise in a combination of Chinese and English

The domain name of Royalstar Group is rongshidagroup.com, in which the three characters "Royalstar" are in Chinese pinyin and "Group" is in English. There are many such examples: the domain name of Chinaren.com is chinaren.com, and the domain name of Huatong Metal is htmetal.com.cn.

6． Add network-related prefixes and suffixes before and after the company name.

Commonly used prefixes include e, i, net, etc.; suffixes include net, web, line, etc.

For example, the domain name of China Marketing Communication Network is emkt.com.cn, the domain name of Internet Marketing Forum is webpromote.com.cn, the domain name of United Business Information is it168.com, the domain name of Pulse Network is mweb.com.cn, and the domain name of China Marketing Network is The domain name is chinam-net.com.

7. Use words or phrases that are different from the company name but are related to the domain name

Generally, there are many reasons why companies choose this kind of domain name: Or because the company's brand domain name has been registered by others as a last resort For this reason, or you feel that a new domain name may be more conducive to conducting online business. For example, The Oppedahl & Larson Law Firm is a legal services firm, and it chose patents.com as its domain name. Obviously, "patents.com" is a more appropriate domain name than a company name. Another good example is Best Diamond Value, a retailer that sells gemstones online. It chose jeweler.com as the domain name. The benefits of this are obvious: even if the company does not make any publicity, many customers will visit it. website.

8. Do not register unique trademark names owned by other companies or trademark names of internationally renowned companies

If you choose a unique trademark name of another company as your own domain name, you are likely to get involved in a lawsuit, especially when the registered domain name is When a well-known trademark of a well-known international or domestic enterprise. In other words, when a company chooses a domain name, it needs to pay attention to whether the chosen domain name is a registered trademark of another company.

9． You should try to avoid URLs generated by CGI scripts or other dynamic pages

For example, the domain name of Minolta Printers is minoltaprinters.com, but after typing this domain name, the domain name column appears "minoltaprinters.com/dna4/smartbroker" .dll?Sid=0&tp=pub-root-index.htm&np=pub-root-index.htm", the reason for this may be that minoltaprinters.com is a free domain name. Such a domain name has many shortcomings: first, it does not comply with the rule that the domain name is part of the homepage; second, it does not comply with the habit of netizens using the domain name as a browsing target and judging their location; third, it ignores the importance of the domain name as a site brand components.

10. Be cautious when registering .net domain names

.net domain names are generally reserved for companies with an Internet background. Although any company can register, it is extremely easy to cause confusion and make visitors mistakenly think that they are visiting a company with an online background. One solution for companies to prevent losses caused by squatting is to preventively register the .net domain name, but not use it as the company's formal domain name.

Some domestic enterprises, including some well-known companies, have chosen domain names ending with .net. For example, there are many free email providers, such as 371.net, 163.net, etc. Foreign online service companies that provide similar services generally choose domain names ending with .com.

======== What you should know before registering a domain name======================

International top Who is the governing body of the domain name?

The international top-level domain name management organization is ICANN, which is a non-profit organization established in recent years to replace NSI. Its main functions include the management of Internet domain names and address systems.

Where is the management agency of China’s national top-level domain names?

What is an IP address?

In the network, we often encounter the concept of IP address, which is also an important concept in the network. The so-called IP address is to assign a unique 32-bit address worldwide to each host connected to the Internet. The structure of IP addresses allows us to easily address addresses on the Internet. IP addresses are usually represented more intuitively by 4 decimal numbers separated by dots. Each number corresponds to 8 binary bit strings. For example, the IP address of a certain host is: 61.135.132.6

< p>Inter NIC (Internet Network Information Center) is responsible for the planning and management of global addresses for Internet IP addresses; at the same time, the three major network information centers, Inter NIC, APNIC, and RIPE, are specifically responsible for IP address allocation in the United States and other regions. Usually, each country needs to set up an organization to uniformly apply for IP addresses from relevant international organizations, and then allocate them to customers.

Address. For example: www.sohu.com that we enter when surfing the Internet will be automatically converted to 61.135.132.6

What is domain name resolution?

People are used to memorizing domain names, but machines only recognize each other’s IP addresses. There is a one-to-one correspondence between domain names and IP addresses. The conversion between them is called domain name resolution. Domain name resolution requires a specialized The domain name resolution server is used to complete the whole process automatically.

What is URL Forwarding?

"URL pointing" refers to pointing your domain name to a fixed link address. For example: if you rent a virtual host service from SOHU, the link address it provides you is /
