[ehsandeep]

@solvecodes got an example to share?

[ehsandeep]

@solvecodes -nW ensure to filter of dead dns entry, i.e dns with NXDOMAIN status, in this case ctf-team.vulnhub.com returns NOERROR, which is valid and nW will not filter it, -nW option doesn't mean or ensure if subdomain is running any website or note, for that you can or need to use httpx to filer them.

dig any ctf-team.vulnhub.com
