To troubleshoot domain name resolution issues when using VolcanoEngine PublicDNS, refer to the following troubleshooting steps:
Check whether your device can access PublicDNS.
Windows
Run the tracert command in the command line. You need to replace IP with the IPv4 address of PublicDNS.
tracert -d IP
If the final result does not display the IPv4 address of PublicDNS, your network connection may have a problem, preventing connection to PublicDNS.
If the final result displays the IPv4 address of PublicDNS, it indicates that PublicDNS may have an issue.
macOS/Linux
Run the traceroute command in the command line. You need to replace IP with the IPv4 address of PublicDNS.
/usr/sbin/traceroute -n IP
If the final result does not display the IPv4 address of PublicDNS, there may be a problem with your network connection that prevents access to PublicDNS.
To determine whether PublicDNS may be experiencing issues, check if the final result displays the IPv4 address of PublicDNS.
