First I would like to say that I would highly recommend this book to anyone that wants to learn more abouot pentesting and Metasploit.

That being said, there are some things about the book that maybe people here can answer. Within the book they show commands that they are using from the msfconsole, one of these commands is Whois. I am wondering, I have not been able to find anything within the Msfconsole for a whois command, is there a module I can load for this? I have searched Google for this information but cannot seem to find it. Any help would be greatly appreciated. Thanks.
