What this article shares with you is about how many sub-domain names a domain name can have. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.

A domain name can have countless sub-domain names, which can be expanded into second-level domain names, third-level domain names and so on. In theory, whether it is a second-level domain name or a third-level domain name, there can be countless domain names.

A sub-domain name is the next level of the top-level domain name (first-level domain name or parent domain name). For example, www.yisu.com is a sub-domain of yisu.com, and club.yisu.com is also a sub-domain of yisu.com.

Among them, news and club all belong to second-level domain names, and these second-level domain names can also be extended into their own sub-domain names, that is, third-level domain names.

How to set the subdomain name?

Go to the domain name management center, and then enter "Domain name Resolution"; in domain name resolution, add CNAME records, such as "news" and "club", and point them to their respective resolution addresses; then go to their hosts and bind these sub-domain names to build websites using these sub-domain names.

Under what circumstances do I use subdomain names?

When there is independent content and there is a lot of content, you can consider setting up sub-domain names to create these content. For example, information centers, forums, shopping malls, mailboxes, etc., are all suitable to be built with independent sub-domain names.

The above is how many sub-domain names a domain name can have. 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.
