Querying the domain registration information


After you know the target domain name, the first thing you would want to do is query the Whois database about that domain to look for the domain registration information. The Whois database will give information about the DNS server and the contact information of a domain.

WHOIS is a protocol for searching Internet registrations, databases for registered domain names, IPs, and autonomous systems. This protocol is specified in RFC 3912 (https://www.ietf.org/rfc/rfc3912.txt).

By default, Kali Linux already comes with a whois client. To find out the Whois information for a domain, just type the following command:

# whois example.com

The following is the result of the Whois information:

Domain Name: EXAMPLE.COM
   Registrar: RESERVED-INTERNET ASSIGNED NUMBERS AUTHORITY
Sponsoring Registrar IANA ID: 376
   Whois Server: whois.iana.org
   Referral URL: http://res-dom.iana.org
   Name Server: A.IANA-SERVERS.NET
   Name Server: B.IANA-SERVERS.NET
