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

A domain name, from a technical level, can open countless second-level domain names. The form of second-level domain name is: *. Domain name. Domain name suffix, second-level domain name depends on the domain name.

Suppose we have a primary domain name yisu.com, and we can create numerous secondary domain names: * .yisu.com. "*" can have its own name. The total length of the domain name is limited to 253 characters.

Is the secondary domain name the same as the secondary directory?

The second-level domain name is different from the second-level directory, for example, the second-level domain name is www.yisu.com; and the second-level directory is like www.yisu.com/cloud/. The second-level domain name can be regarded as an independent domain name, and the secondary directory cannot exist independently.

Can you build countless second-level domain names?

From the technical level, we can set up numerous secondary domain names through one primary domain name. But in practice, the service will limit the parsing time, and if you need to expand the quantity, you have to pay for it.

The above is how many second-level domain names can be resolved. 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.
