This article uses easy-to-understand examples to introduce how to check whether the domain name is walled. The content is very detailed. Interested friends can use it for reference. I hope it can be helpful to you.

Domain name wall means that the website is blocked by the national Great Firewall. Generally, the site is blocked because it contains illegal or sensitive information.

The form of the domain name being walled: the domain name resolution is normal, there is no problem on the server side, but the website just can't be opened.

How to judge whether it is by the wall or not

1. Domain name is blocked: if the domain name ping cannot open the website (excluding server downtime), it can be opened by proxy or VPN, which generally means that the domain name is blocked. If the website under the domain name has illegal information and does not correct it, it will be directly dropped by the GFW wall, and the result is that the access domain name cannot be opened, but the resolution is normal. At this time, the domain name cannot be used at home, and it can be accessed and used abroad.

two。 The domain name is blocked intermittently: if it can be opened intermittently, if it cannot be opened, it can be opened by a foreign agent, indicating that the domain name is intermittently blocked (of course, this may also be caused by the instability of domestic DNS resolution).

If illegal information appears in the website under the domain name, it can not be opened temporarily and can be opened later, it is generally judged as intermittent blocking, and the way to deal with it is to delete the sensitive information entry of the website.

3.IP blocked: if ping is not available, you can use a foreign agent to open it. It is generally determined that ip is blocked. Generally speaking, if your domain name resolution address is foreign, it will be walled. If you bind a domestic IP, it will not be walled. If you find that a domain name is walled, it is best to parse the domain name immediately and do not keep it on your server.

In addition, there are many domain name wall detection tools on the Internet, which can be directly entered into the domain name for detection.

If you are using a foreign record-free space, you can generally solve it by moving back to China after the domain name is put on record.

If the IP is blocked, contact the host company to replace the IP or purchase a separate IP, the general problem can be solved.

If your domain name is blocked directly, it is best to check whether the content of the site is compliant. If there is nothing wrong with the content, you can contact ISP, such as local telecom, and ask the other party to check. Sometimes they can help remove the site from the blacklist.

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