A subdomain is a domain that is part of a larger domain. For example, in 'blog.example.com', 'blog' is a subdomain of 'example.com'. Organizations use subdomains to organize and navigate to different sections or services of their websites.

How does subdomain enumeration work?

Subdomain enumeration typically involves various techniques including DNS queries, SSL/TLS certificate analysis, search engine results, and public records. This tool uses passive reconnaissance methods to discover publicly available subdomain information.

Is subdomain enumeration legal?

Subdomain enumeration itself is not illegal as it only discovers publicly available information. However, it's important to have authorization before performing any security testing, as some organizations may consider unauthorized enumeration a security violation.

Why are some subdomains not discoverable?

Some subdomains might not be discoverable because they are: not publicly listed, protected by security measures, newly created, or no longer active. This tool only finds subdomains that are publicly accessible and documented.

How accurate are the results?

The results show subdomains discovered through public sources and DNS records. While we strive for accuracy, some subdomains might be outdated or no longer active. Always verify critical findings independently.
