This article uses easy-to-understand examples to introduce how to query whether the domain name is resolved, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Sometimes we find that even if the status of the domain name is normal, the website may not be accessible for a period of time after the resolution is submitted. This is because the process of domain name resolution is very complex, which needs to be updated step by step through the global domain name system, and the DNS server called by users on the Internet also has a cache. Only when the cache expires and re-reads the resolution record of the root database can the resolved IP address be seen by the viewer.

Generally speaking, domain name resolution usually takes 2 hours to take effect. If you find that the website cannot be opened after a few minutes of resolution, it is basically due to the fact that the resolution has not yet taken effect. So, how do you check whether the resolution of a domain name is valid?

1. In the windows system, click "start", select "run" (or desktop key + R), and then enter "cmd" to enter the dos window.

two。 Then type "ping your domain name" in the window, and if your website space IP is displayed correctly, the new domain name resolution has taken effect; if the screen is black and there is no IP information, the new resolution has not yet taken effect.

In domain name resolution, if the relevant parameters are set incorrectly, for example, your domain name is resolved using CNAME aliases, and the alias resolution address is wrong, which will also cause the website to fail to open.

The solution is as follows: open the FTP or host background control panel, check whether the parameters are set incorrectly, and correct the data in time.

The reason why domain name resolution is not effective

In addition to network delay and incorrect settings, it will also be affected by DNS hijacking and abnormal domain name status. DNS hijacking is the key factor causing the current domain name resolution errors. We can improve the security of the virtual space by increasing the virus detection efforts of the server.

To know whether the domain name status is abnormal, you can also simply infer through the whois query. If the domain name status is clienthoold (pause resolution) or severhold, the domain name resolution is prohibited. In this state, the domain name resolution cannot take effect even if the domain name resolution is set, so the domain name cannot be accessed. Contact the domain name registrar to cancel this status.

On how to query whether the domain name resolution is shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
