[lacnog] Resolución inversa 170.80.0.0/16

[Gerardo Guerrero]

Hola a todos

Alguien se ha visto en la necesidad de hacer resolución inversa con IPs 
asignadas por LACNIC del segmento 170.80.0.0/16?, al parecer en un 
principio estaba asignado a ARIN pero fue cedido a LACNIC, el tema es 
que a la hora de querer resolver inversamente, la solicitud se queda en 
servidores de ARIN, ya lo reporte con ellos pero me mandan a LACNIC, 
pero según yo falta que ARIN delegue el segmento 170.80.0.0/16 a Servers 
de LACNIC. (Ya revise mis DNS Servers y si resuelven autoritariamente 
por el segmento asignado en cuestión).

Prueba de DNS Query hacia IP ejemplo 170.80.28.1

/Step 1//
//We are at the first step. All DNS queries, if not previously cached 
(and we do NOT cache), starts from the root servers.//
