What is a second-level domain name? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.
The second-level domain name is the English abbreviation SLD of Second-level domain;. It is a domain under the top-level domain name in the DNS level of the Internet. The secondary domain name is the penultimate part of the domain name, and the secondary domain name is the domain name separated by the primary domain name.
1) the secondary domain name is the domain name deposited under the primary domain name.
2) the second-level domain name belongs to an independent branch, with its own collection, snapshot, PR value, anti-chain and so on.
3) when the primary domain name is punished, the secondary domain name will also be punished.
Under the top-level domain name, the second-level domain name in China can be divided into two categories: category domain name and administrative domain name.
Category domain names include ac; international domain name com for scientific research institutions, edu; for educational institutions, gov; for government departments, net; for Internet network information centers and operation centers, org for non-profit organizations, and so on. The administrative domain names correspond to China's provinces, autonomous regions and municipalities directly under the Central Government.
Top-level domain names, second-level domain names and third-level domain names are only addressed by dots from right to left. For example, abc.com.cn where cn is the top-level domain name, com is the second-level domain name, and abc is the third-level domain name; for example, abc.com where com is the top-level domain name and abc is the second-level domain name.
