How can i hide my subdomains from subdomain scanner websites? I don’t want anyone to know so easily via dnsdumpster.com for e.g. what subdomains my website have.
That’s impossible, as DNS records are public. The best you can do is use Firewall Rules to block unwanted traffic to that subdomain.
Or…you delete that DNS record and add those subdomains to your on-site DNS or localhosts file.
Even pentest-tools.com also provides similar feature. So yeah, the best thing you can do is to secure your subdomain.
