Most people do not understand the knowledge points of this article "how to detect domain names by walls", so the editor summarizes the following contents, detailed contents, clear steps, and has a certain reference value. I hope you can gain something after reading this article. Let's take a look at this "how domain names are detected by walls" article.

Domain name is walled

If the domain name ping cannot open the website (excluding server downtime), you can use a proxy to open it. Generally speaking, the domain name is blocked. If the website under the domain name has many illegal information, sensitive, and does not rectify, it will be directly dropped by the GFW wall, and the result is that the access to the domain name cannot be opened. But parsing is normal. At this time, the domain name cannot be used at home, and it can be accessed and used abroad.

Domain names are intermittently blocked

If it can be opened intermittently, when it cannot be opened, it can be opened with a foreign agent, indicating that the domain name is intermittently blocked (of course, this situation may also be caused by the instability of domestic DNS parsing). If illegal information appears on 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 keywords of sensitive information entries.

IP is blocked.

If the ping does not work, you can use a foreign agent to open it. It is generally certain that the ip is blocked.

Note: 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.

What if the domain name is walled?

1. Use domestic servers

2. Bind a new domain name to the server and use a domestic forwarding server to jump the walled domain name to the new domain name.

When using the second method, the weight of the original domain name can be transferred to the new domain name by setting 301 and site-wide forwarding.

If you use a domestic server, you have to put it on record honestly, and for the record, you have to shut down the website for more than ten days. The original choice of the Hong Kong host is to avoid the pain of filing, and it is really remorseful to go back to the origin in a circle.

The loss of replacing a new domain name is even greater. At the beginning, it took a lot of effort to rush to register the domain name, and the name of the website and so on are all based on this domain name, and it takes several months for 301 to forward the existing inclusion and weight, which is more painful than changing the domestic server for the record.
