-# Puedo especificar dos cosas:
-# 1) Hints: Direcciones y/o dominios
-# 2) Filtros: Direcciones y/o dominios
-#
-# Si son hints, las uso para explorar. Si son filtros, los resultados 
-# tienen que pertenecer a los filtros
-# 
-# # Cosas para hacer:
 #
-# ** Si especifico Dominios como Hints: **
-# 1) Busco esos dominios en los buscadores
-# 2) Para todos los dominios encontrados, busco A, AAAA, NS, MX
-# 3) Incluyo dominios de otras zonas. Pero no sigo buscando en esas zonas.
-# 4) De todo lo que encontre, obtengo direcciones, y tomo los /48 (salvo que el usuario haya decidido trabajar con /64)
-# 5) Solo si trabajo con /48: Hago traceroute a todas las direcciones, y solo me quedo con aquellas que estan en los /48 anteriores.
-# 6) A cada prefijo (/48 o /64) le hago dnsrevenum6
-# 7) Si hay dominios nuevos, aplico la misma logica (desde #1)

-# ** Si especifico dominios como filtros **
-# Cada vez que obtengo un dominio de algun tipo, me fijo si está en la lista/zona. Si no lo está, lo descarto.
