Roque,

Solo una aclaracion: el rol del ASO Address Council no es el de coordinar
politicas globales, si no el de presentarlas correctamente al Board de ICANN
para su aprobacion.
Una politica global debe surgir de los foros publicos de los RIR, haber sido
aprobada por las comunidades de los cinco RIRs con el mismo texto e
involucrar a ICANN/IANA, recien en ese punto entra en accion el ASO AC. 

Saludos

SB

countdownpolicy proposal


Roque:

Por ahora es una propuesta de personas de la región de Asia y Pacífico para
discutir en APNIC. 
Se está discutiendo en este preciso momento en la reunión de APNIC en Bali.
Si la propuesta tiene apoyo en esa región, asumo que la comunidad de APNIC
dará los pasos correspondientes para plantearlo como una política global.

Saludos.

Raúl
