How to make sure the server's IP or domain is clean
فارسیFirst, check the server's IP or domain on the Check-Host site.
After entering the IP or domain in the specified field; You must specify the type of test.
This test is useful when you have created the server for the first time and has nothing installed on it. In this case, you can use this option.
If the result of the test was 4/4, it means that the server's IP is most likely clean. Otherwise, you need to change the IP.
This test is used when the operating system is installed and the firewall is active. In this case, you can test the server via the port on which service is running. For example, VPN panels mostly use TCP port 443. Therefore, this port can also be used for testing.
If the result of the test was like the picture above, the server's IP is probably without any problems. Otherwise, you need to change the IP.
This test is used when the operating system is installed and the firewall is active. In this case, you can test the server via the port on which service is running. For example, all servers use DNS service, which works on UDP port 53. This port can also be used for testing.
If the result is like the image above, it means that the connection is not established on the UDP protocol and it is likely the server's IP is not clean.
First, open the site from here.
Ping and TCP tests can be used to check the IP or domain of the server on this site, which according to the previous explanations, the use of each is clear.
Please note that you have to choose the location based on your region. If the results are all good, it is very likely that your server's IP has no problem.
If the result was shown as OK, there is a high probability that your server's IP has no problem.
