[lacnog] Resolución inversa 170.80.0.0/16

Mie Ago 9 15:44:46 BRT 2017

Hola Gerardo,

Gracias por reportar este problema.

como detalle, el /16 no se debe delegar sino que usamos un esquema 
llamado de “zonelets” en la cual nosotros compilamos parte de la 
zona 170/8 y se la subimos a ARIN para que ellos la incluyan en sus 
zonas. Eso igual es un detalle, para ti como usuario debira ser 
transparente.

¿Cual es el bloque que tienes delegado? ¿el /16 entero?
