Tool 196: WHOIS client
  
  Description:
   
  This tool is a whois client.
  It obtains information about an object (generally a domain name).
  User has to specify a whois server (whois.internic.net, etc.).
  For example: netwox 196 --dst-ip whois.nic.fr --query enterprise.fr
  
  Parameter --dst-ip is the address of remote host/server.
  Parameter --dst-port is the port number where to connect.
  Optional parameter --src-ip defines the local IP address to use.
  Optional parameter --src-port defines the local port number to use.
  Optional parameter --ip4opts permits to add IP4 options encoded as
  mixed.
  Optional parameter --ip6exts permits to add IP6 options encoded as
  mixed (first byte is the next header number).
  Optional parameters --device, --src-eth and --dst-eth permits to
  create a virtual client using fake addresses (in this case, tool have
  to be run with admin privilege in order to sniff and spoof at
  Ethernet level).
   
  Usage:
    netwox 196 -i ip -q hostname [-d device] [-E eth] [-e eth] [-I ip] [-P port] [-p port] [-o ip4opts] [-O ip6exts] [-T uint32]
