From a technical perspective, domain names are a method used on the Internet to resolve IP address correspondence. A complete domain name consists of two or more parts. Each part is separated by an English period ".". The part to the right of the last "." is called a top-level domain name (TLD, also called a first-level domain name). , the left part of the last "." is called the second-level domain name (SLD), the left part of the second-level domain name is called the third-level domain name, and so on, each level of domain name controls the allocation of its next-level domain name.

Top-level domain names are defined and allocated by ICANN, which is controlled by the US government, and are divided into general top-level domain names (gTLD, General Top Level Domain, also known as international domain names in China) and country code top-level domain names (ccTLD, Country Code Top Level Domain).

Among the generic top-level domain names, there are only three generic top-level domain names: .com, .net and .org, which are managed by InterNIC (currently ICANN entrusts Network Solutions of the United States to undertake the operation and management of InterNIC) , there are more than 240 country code top-level domain names, which are represented by two-letter abbreviations, representing different countries. .cn is China's country code top-level domain name and is managed by CNNIC (currently the Chinese government entrusts the Computer Network Information Center of the Chinese Academy of Sciences Responsible for the operation and management of CNNIC).

From a business perspective, a domain name is a "company's online trademark." Companies attach great importance to their trademarks, and as an online trademark, the importance and value of domain names have been recognized by companies around the world. Both domain names and trademarks are unique within their respective scopes, and with the development of the Internet. From the perspective of corporate image building, domain names and trademarks are closely related. Therefore, domain names and trademarks have certain unique characteristics. When many companies choose a domain name, they often hope to use a domain name that is consistent with their corporate trademark. However, domain names are more unique than trademarks.

From the perspective of domain name value, domain name is the most basic thing on the Internet and a rare global resource. Whether you are doing ICP and e-commerce, or carrying out other activities online, you must start with the domain name. , a domain name that is justifiable and easy to promote is the first step for the success of Internet companies and websites.

※Why register a domain name?

The Internet, the darling of the information age, has stepped out of its infancy and is known to more and more people. E-commerce, online sales, and online advertising have become hot spots in the business world. "Going online" has become a mantra for many people. However, if you want to set up a server to publish information online, you must first register your own domain name. Only with your own domain name can others access you. Therefore, domain name registration is the basis for establishing any service on the Internet. At the same time, due to the uniqueness of the domain name, it is very necessary to register as early as possible.

Therefore, it has certain characteristics in common with trademarks. When many companies choose a domain name, they often hope to use a domain name that is consistent with their corporate trademark. However, domain names are more unique than trademarks. For example:

There was a domain name registration conflict between an electronics group company and a Japanese chemical factory that also held the Panda registered trademark. According to the "Interim Measures for the Administration of Internet Domain Name Registration in China", Both companies have the right to register panda as the domain name, but there is only one panda.xxx.cn. Then, when the domain name applications comply with the provisions of the "China Internet Domain Name Registration Interim Administrative Measures", CNNIC will register on a first-come, first-served basis. "The application will be processed according to the principle of ". A certain daily chemical factory first applied for panda.xxx.cn, and an electronics group company submitted an application for the panda.xxx.cn domain name only after the certain daily chemical factory had successfully registered and the website had been launched. The result was that an electronics group The company can no longer use panda.xxx.cn as its domain name.

It is not difficult to see from the above example that although a certain electronics group company can still sell its panda brand appliances, it may never be able to let its users see its www.panda.xxx .cn website. This is undoubtedly a pity.
