Whois is a tool to collect information about Internet domains. With this tool you can find out contact and domain registration information. and even the name and contact information of the website owner.
This is very useful when you are using OSINT methods to investigate a target, but there are times that the target has privacy whois activated or the domain currently no longer exists. Therefore, it is currently not possible to know enough information about the owner of the domain.
One of the most useful tools for OSINT investigations regarding the whois system is whoisxmlapi (Domain Research Suite). It will show the whois history of any internet domain.
information that you can collect with this tool:
- hosting company history
- registrar name history
- nameserver (DNS Zone) history
- Registrant contact history
- Administrative contact history
- Technical contact history
- Email Direccion history
This information for osint operations is very useful, many domain webmasters forget to add privacy whois and activate it months after registering the domain.
Also in some cases when transferring the domain to a new registrar, a domain may lose the privacy whois. and this exposes the information in whois.
and in case this has happened, you can check if this Domain Research Suite tool has collected this information.
With this tool you will be able to see the domains that match an email that appears or has previously been in the whois records.
This can be useful for researching and collecting domains from the same person you are researching.
The Domain Research Suite tool is an excellent domain intelligence tool. In addition to doing all of the above, you can also see the DNS history and the domains connected by the website’s IPv4 address.
The most useful thing to find with this tool is to find the email address, first and last name, country, whois data and other very useful information that you can find with this OSINT (open-source intelligence) tool.
