Quickly check common subdomain prefixes and their public DNS resolution results.Subdomain Detection Instructions
Quickly check common subdomains with public DNS
The tool will make a public DNS query on a set of common prefixes to help find the subdomain names that have been configured and resolved, suitable for asset self-examination and basic troubleshooting.detection range
The common prefix dictionary is currently used for quick inspection, not a complete enumeration, and does not bypass access control or scan target ports.
The meaning of the result
If you find that the record indicates that the name is publicly resolved, it does not mean that the corresponding website or service must be accessible.
Wildcard parsing
Some domain names resolve any prefix to the same address, which may result in the existence of a seemingly large number of subdomains.

Please only conduct security tests on your own or authorized domain names and comply with applicable law and service terms.
