What is the reason for DNS resolution failure?

DNS (Domain Name System) resolution failure may be caused by many reasons. The following are some possible reasons:

1. Network problem : DNS resolution may fail due to network connection issues. Check whether the network connection is normal and make sure you can access the Internet.

2. DNS server problem: If there is a problem with the DNS server or it is unavailable, it may cause DNS resolution to fail. You can try to use another DNS server or contact the network administrator to solve the problem.

3. Domain name spelling error: If the entered domain name is spelled incorrectly, DNS resolution will also fail. Make sure the domain name you enter is spelled correctly.

4. DNS cache problem: Sometimes there may be a problem with the DNS cache on the local computer or router, causing resolution failure. You can try clearing the local DNS cache or restarting the router.

5. Domain name registration issues: The domain name may not be registered correctly or the domain name registration information may be incorrect, which may also cause DNS resolution to fail. Contact the domain name registrar to solve the problem.

6. Firewall or security software: Firewall or security software may be blocking DNS resolution requests. You can try to disable these software for testing.

7. Domain name server setting problem: If the domain name server record is incorrect or the domain name server setting is incorrect, DNS resolution may also fail. Check whether the domain name server settings are correct.

8. DNS hijacking: Sometimes ISP or other network providers may perform DNS hijacking and redirect the user's DNS resolution request to the wrong server, causing resolution failure.

The above are some common reasons that may cause DNS resolution failure. Solving this problem may require troubleshooting and adjustment of the network, DNS settings, domain name registration and other aspects.
