Creo que un punto que no podemos perder desde el punto de vista de los operadores
es que si se mantiene el /48 como unidad de asignación, se deberá registrar
a cada usuario residencial (ADSL, etc) en la base de datos Whois, con el
correspondiente costo administrativo y con un agravamiento de los problemas
de confidencialidad ya planteados en esta lista.
