This is the official manual of the Ruby Whois library.
Whois is an intelligent — pure Ruby — WHOIS client and parser.
It exposes an object oriented Ruby API to look up WHOIS information contained in the databases maintained by the Network Information Centers (NICs). The response is converted into a pure Ruby object and can be easily printed or manipulated using the Ruby programming language.
It also offers command-line interface to run WHOIS queries from the console.
