ICANN WHOIS VS ViewDNS.info

If you do a WHOIS lookup on the domain (usually at lookup.icann.org), then it should tell you the current registrant. There should be an email address or a way of contacting the current registrant. You may need to also go to the registrar where it's currently registered to contact them. But it's an ICANN requirement/rule that there MUST be a way to contact the current registrant through email or a form. Source: 10 months ago

Did you try doing a search on whois/lookup? Doing so, you will be able to see if your domain name is now handled by a different registrar. If that turns up no helpful results & the company you originally leased the domain name from was accredited by ICANN; it may be worthwhile to reach out on their support page. Source: 10 months ago

I used viewdns.info - allowed me to search by registrant name. I looked for Bed Bath Procurement and Liberty Procurement for the list I grabbed (~600 results). Spotted the .sex TLD and filtered down to that and hand-verified whether each result was truly owned by BBBY. I work in IT Audit and InfoSec, so was a piece of cake to find and filter the data. :D.

After doing some investigating, it looks like when I sent the email, it was initially sent via an IP address that falls within Googles IP range, but when I went to viewdns.info to lookup the IP, it was of a Domain that was not Google. Source: over 1 year ago

Normally that means that every target that belongs to the company, is in scope except the one in the OOS section. Now the real question his, how can I be sure that a target is in scope? Well, whois command is your friend, if you have a domain name. If you have a ip address, you have to work more on it, anyway you can try some reverse DNS or other tool that you can find here: https://viewdns.info/ or you are... Source: over 1 year ago
