/**
 * Title:    HEX IP to DEC IP Converter
 * Description:  This simple proggy helps you figure out the
 *        DEC correspondant of an IP represented in
 *        HEX format. This is useful when trying to
 *        figure out the ip of a user connected to a
 *        Java IRC Chat such as the one on www.ircnet.com.
 *        Code is OpenSource under the terms of the GNU
 *        General Public Licence. I will not be held
 *        responsable for any appropriate use you make
 *        with this code (ie: you get an ip and then start
 *        a DDoS attack towards it etc.)
