[lacnog] Signing of the ARPA zone

[Joao Damas]

no hay mucho que decir, la verdad.
La zona .arpa del DNS está ahora firmada con DNSSEC y se está  
trabajando en limpiar la estructura de delegaciones en arpa para a  
continuación firmar con DNSSEC las zonas contenidas en arpa (por  
ejemplo in-addr.arpa, ip6.arpa, etc), e164.arpa ya está firmada desde  
hace tiempo.
Ahora se pueden verificar las respuestas de DNS configurando la clave  
para .arpa en su servidor de nombres y a partir de julio, cuando se  
firme también la raíz del DNS (el dominio ".") se podrá seguir la  
cadena de verificaciones desde ahí.

Posteriormente imagino que los RIRs irán firmando sus zonas bajo in- 
addr.arpa e ip6.arpa y asi hasta llegar hasta los usuarios del espacio  
de direcciones que mantienen su propio DNS inverso

Saludos
Joao
