What this article shares with you is about what is the national top-level domain name. The editor thinks it is very practical, so I hope you can get something after reading this article. Let's take a look at it with the editor.

The national top-level domain name is also called the country code top-level domain name, which mainly refers to the abbreviation of the country's name, and the country code top-level domain name indicates the country region, such as .cn in China, .us in the United States, .fr in France, .jp in Japan and so on.

The country code top-level domain name is managed by the Internet Network Information Center (NIC) of each country. For example, our cn domain name is managed by the China Internet Network Information Center (CNNIC).

The birth of the domain name is to omit the trouble of remembering IP numbers, so use characters instead of numbers to open the website, and the IP numbers and characters are parsed by dns to form a domain name. After having a domain name, you can access the website directly through the domain name.

Among the top-level domain names, there are not only national top-level domain names, but also international top-level domain names, such as .com, .top, .net, .org, .gov, .edu, .biz and so on.

If the international top-level domain name is used to build a site, the .com domain name is generally preferred, because the .com domain name is the most common and easier to remember and search. According to the survey, the domain name ending in .com is more conducive to SEO optimization.

In addition to top-level domain names, there are second-level domain names, third-level domain names and multi-level domain names. A second-level domain name refers to a domain name under a top-level domain name. For example, www.yisu.com is a second-level domain name.

A third-level domain name is a domain name shaped like m.www.yisu.com, which can be understood as a sub-domain name of a second-level domain name. Generally speaking, a third-level domain name is free. Multi-level domain names continue to be added at the original domain name.

The above is what the national top-level domain name is, the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
