/*
** DNServer (Public Domain)
** Cesar Rodas <saddor@guaranix.org>
**
** The Idea is to give a simple way to handle DNS querys and retrives an IP.
** This project could be used as a DNS Trafic Balancer to mirrow sites with a
** close geografic position, of course with a IP2Country Module.
****************************************************************************************
** La idea es dar una manera de manejar las peticiones de DNS y retornar un IP.
** El proyecto puede ser usado como un Balanceador de Trafico hacia sitios espejos
** con una posicion geografica cercana, desde luego que con un modulo de IP2Country.
