Reverse Lookups with Forwarders

[Jason Hellenthal]

Only thing I see to be missing here is actual Class B address space 172.16/12 but instead you are trying to forward from Class A public address space assigned to FACEBOOK. I don't quite think you will get that to work... That is unless you are the Facebook authoritative server...

 range:       172.0.0.0 > 172.15.255.255                                     range b10:   2885681152 > 2886729727  range b16:   0xac000000 > 0xac0fffff  hosts:       1048576                  prefixlen:   12                       mask:        255.240.0.0


Was this just an intentional obfuscation ?
