Whois is a tool for collecting information about Internet domains. With this tool you will be able to know contact information and domain registration. e the name and contact information of the website owner. There are ways to hide this but you can look for privacy errors using tools to view WHOIS history
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. This tool provides a WHOIS database from at least 2011 until now, so it is very useful
information that you can collect with this tool:
- hosting company history
- registrar name history
- nameserver history
- Registrant contact history
- Administrative contact history
- Technical contact history
- Email address 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.
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. You can also do this same with other fields.
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.
