In fact, it is very common for corporate domain names to be inaccessible. Analyzing and solving corporate domain name inaccessibility is also a basic skill that webmasters need to master. However, there are many factors that affect the normal access of corporate websites. Today, the editor has specially sorted out the relevant reasons. Friends who don’t know yet, come and have a look!
Generally speaking, corporate websites mainly include website domain names, space and programs. If corporate domain names are inaccessible, we can analyze them from the above three factors:
1. Domain name expiration
Domain name expiration is one of the reasons why corporate domain names cannot be accessed. Although this kind of careless mistake is not common for enterprises, it cannot be guaranteed that everyone will not ignore the domain name renewal problem. For corporate domain names that cannot be opened due to this reason, you only need to renew them in time.
2. Domain name resolution
The domain name resolution process is relatively complicated. It needs to go through the global domain name system and requires cache time, so the website status is not updated in time. After confirming that the resolution is normal and the domain name status is normal, if the corporate domain name cannot be accessed, it may be that the resolution has not yet taken effect.
Under normal circumstances, it takes about 2-3 hours for the domain name to be resolved and take effect. If the website cannot be opened normally within a short time after resolution, it is recommended to wait patiently.
However, parsing errors can also cause the enterprise domain name to be unable to open, such as related parameter errors, address errors, etc. At this time, you need to open the FTP or control panel to check the parameter settings.
3. DNS hijacking
DNS hijacking is the key factor that causes the enterprise domain name to be inaccessible, but there is no good way to prevent it. At this time, you need to increase the antivirus strength of the space to ensure security.
4. Abnormal status of the enterprise domain name
Abnormal domain name status can also cause the enterprise domain name to be unable to open, such as the domain name is blacklisted, or the status is clienthoold. In this state, it is prohibited to resolve, and you can only contact the registrar to cancel the status.
