Wildcard root question #38

Closed riramar closed 1 year ago

riramar commented 1 year ago

Thanks for the amazing tool! When you have multiple subdomains under the same wildcard root, puredns won't return any subdomain. For example:

au.site.yahoo.com matrixcollectibles.site.yahoo.com

Wouldn't be interesting to return at least one subdomain from the list above? If an user is filtering valid domains for security testing, he/she could miss valid subdomains from wildcard roots domains.

Hi,

Unfortunately this is not something that puredns can detect by looking at the DNS entries. It would require a tool that fetches the web page and compares the results, which it is not suited for. I would probably use ffuf or something similar instead?
