ViewDNS offers a nice, online collection of DNS and OSINT tools. The tools are also offered as an API to give webmasters the ability to easily integrate them into their own sites. A free API "sandbox" account has a monthly limit of 250 queries. Our appreciation for the recommendation goes to CingularIT. - Source: Reddit / 2 months ago
Tried a couple online ones (https://pentest-tools.com/information-gathering/find-subdomains-of-domain and https://dnsdumpster.com/) , neither are able to. The former's paid version is too costly to even try :s. - Source: Reddit / 2 months ago
I've tried so far with many online based subdomain finders (one mentioned in OP + https://pentest-tools.com/information-gathering/find-subdomains-of-domain + https://dnsdumpster.com/) but none have been able to detect the hidden URLs of my site yet. I'll try GoBuster, but again, if it needs me to have linked the routes to the hidden URLs somewhere on my homepage, I'm guessing it will fail too. - Source: Reddit / 2 months ago
Https://dnsdumpster.com/ is another good one . Its also funny to send to management. Mine truly is a dumpster. - Source: Reddit / about 2 months ago
I defiinately don't recommend that. I just have to clean up all the mass where I work because someone used this "strategy" and now our entire infrastructure can be mapped in 5 secunds using DNS Subquery. Please test your stack by searching for yourdomain.com here: https://dnsdumpster.com/. - Source: Reddit / about 2 months ago
