for website operators and domain name holders, the domain name cannot be accessed normally is a very troublesome problem, and the domain name is one of the common reasons. When many people encounter domain name access failures, they often cannot accurately determine whether it is a wall or an ordinary network problem, which requires mastering professional domain name wall query methods. This article will comprehensively explain the relevant skills of domain name wall query from multiple dimensions such as basic judgment, practical operation methods, and follow-up processing, and help you quickly locate the status of the domain name and avoid unnecessary losses caused by judgment errors.
before conducting a formal domain name wall query, understanding the basic judgment logic can help you initially screen problems and reduce unnecessary operations.
1, distinguish between domain name wall and ordinary fault
domain name wall usually shows that the domestic network cannot be accessed, but the overseas network can be opened normally; and the ordinary network failure is generally inaccessible at home and abroad, or some users in the same area can access some cannot. In addition, after the domain name is walled, the use of domestic DNS resolution may not be able to obtain the correct IP, or the obtained IP cannot be pinged in China, but the overseas ping result is normal.
2, confirm the validity of the domain name itself
before carrying out the domain name wall query, it is necessary to confirm whether the domain name is in a normal state, such as whether it has expired and not renewed, and whether it has been suspended by the domain name registrar due to violations. You can check the WHOIS information of the domain name through the official website of the domain name registrar to check the expiration time and status of the domain name. After excluding such basic problems, it will be more efficient to conduct the domain name wall query.
mastering the practical operation method is the core of completing the domain name wall query. The following methods cover different scenarios and are suitable for various user operations.
1, the use of online domain name wall query tool
there are many professional online platforms to provide domain name wall query services, such tools are simple to operate, just enter the domain name to quickly obtain results. Some tools will also detect the DNS resolution of the domain name, domestic and foreign accessibility and other information to give a comprehensive judgment. However, pay attention to choosing a regular platform to avoid leaking information after entering the domain name. It is recommended to choose a tool with a good reputation in the industry.
2, the auxiliary domain name is queried by the wall through the ping command
use the ping command that comes with the computer system, it can also perform a preliminary domain name wall query. In the domestic network environment, if the target domain name is pinged, if there is a prompt such as request timed out and unable to access the target host, you can switch to an overseas server or use a VPN to ping again. If overseas ping can normally obtain IP and receive a response, it can basically determine that the domain name may be walled. It should be noted that some servers have disabled the ping function, which needs to be judged in combination with other methods.
3, with the help of DNS resolution and comparison of domain names by wall query
the domain name is walled, the domestic DNS server may not return the correct resolution result. Domestic public DNS and overseas DNS can be used to resolve the target domain name respectively, such as domestic 114.114.114.114 and overseas 8.8.8.8. If the Internet Protocol Address resolved by the two is quite different, or the domestic resolution has no results, the overseas resolution is normal, and it can also be used as a reference for the domain name being walled query.
complete the domain name wall query and confirm that the domain name is wall, take timely measures to restore website access as soon as possible.
1, apply for domain name unblocking
If the domain name is blocked due to misjudgment or non-serious violations, you can submit an application for unblocking to the relevant management department. When applying, you need to prepare the ownership certificate of the domain name, the website compliance certificate and other materials, and submit them according to the official process. However, the unblocking process usually takes a long time and requires patience to wait for the review result.
2, change domain name or use CDN to accelerate
if it is difficult to unblock or the waiting time is too long, you can consider replacing the new domain name and migrating the website content to the new domain name. In addition, you can also try to use the domestic compliance CDN service to allow domestic users to visit the website normally through the way of CDN node jump, but this method needs to ensure that the website content complies with relevant regulations and avoid being blocked again.
do a good job of controlling the details of the domain name being queried by the wall, which can improve the accuracy of the results and avoid other problems.
1, multiple cross-validation query results
single domain name wall query results may have errors, such as tool cache, network fluctuations and other factors may affect the judgment. It is recommended to use a variety of methods for cross-verification, such as online tools, ping commands, DNS resolution and comparison at the same time. The results obtained after multiple verifications will be more accurate.
2, avoid illegal operations in the inquiry process
in the domain name wall query, do not try to use illegal tools or over the wall software for batch query, such operations may violate the relevant regulations, but also may lead to their own cyber security threats. You should choose compliance to carry out domain name wall query, to ensure the legitimacy and security of the operation.
To sum up, domain name wall query is a necessary skill for website operators, from basic judgment logic to practical operation methods, to follow-up responses and precautions, each link is crucial. Through the explanation of this article, we can quickly master the core skills of domain name wall query, accurately judge the status of the domain name, and take effective measures in time when encountering problems to ensure the normal operation of the website and user access experience.
