The purpose of this article is to share with you why the resolution of the virtual host domain name failed. The editor thinks it is very practical, so I hope you can learn something after reading this article. Let's take a look at it with the editor.

For the establishment of the station, the domain name and the host are impossible or missing, the virtual host should bind the domain name, and the domain name should be resolved to the host address. Many website builders may have been plagued by domain name resolution errors, which has affected the website operation and optimization work. Domain name resolution error is a very common network failure, which is caused by many reasons.

For example, parsing settings problems, website space factors, virus attacks and domain name vendor server errors and so on. If it is not solved in time, it will directly affect the user experience and lower the evaluation of the website by the search engine.

The network is not available

Generally speaking, it refers to the network operator, such as China Mobile, China Unicom or China Telecom. If there is a problem with the network operator, the virtual space of the server will also display a domain name resolution error. This rarely happens, but if it happens, it is usually the optical cable or network line of the operator that is blocked.

It is also possible that the improper construction of the construction unit will cause line damage, which will lead to similar problems in the network in a certain area, and all network communications will be interrupted, so the background of the operator server will not be able to connect to the background server of the client. There will be a network failure. The solution is to contact the network operator as soon as possible to solve the problem and repair the line. when the line is repaired and the server resumes normal operation, the problem of domain name resolution failure will not exist.

There is a virus / attack

Domain name hijacking may also lead to the failure of domain name dns resolution or the existence of a virus in the website space. If the server of the client encounters a virus invasion, then the user needs to check and kill the background virus Trojan to remove the interference of the virus to the server; if the server encounters a virus intrusion, it is a problem in the professional field. need to contact the website space merchants, merchants for virus clearance, and do a good job in later maintenance, so as not to affect the use of customers.

Whether parsing is prohibited

Check the domain name status with the whois tool. If the domain name status is clienthold or serverhold, resolution is prohibited. You need to contact your domain name registrar to solve the problem.

Whether the record and cache are updated

Check whether the authoritative DNS cache record is valid; in addition, if the dns domain name resolution fails for a long time, it is mostly caused by the failure to update the dns cache record. You should also contact your domain name service provider.

Domain name resolution is the conversion process from domain name to IP address, and the domain name resolution is completed by the DNS server. Therefore, the problem of domain name resolution is closely related to the server where the virtual host is located.

The above is why the resolution of the virtual host domain name failed. 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.
