Simple reverse dns

  • 772

it would be $ORIGIN 113.168.192.IN-ADDR.ARPA. for a 255.255.255.0 netmask

but what would the origin be for a netmask of 255.255.128.0

    If I understood you correctly, you are looking to create a reverse DNS allocation for /17 with one $ORIGIN, thats not possible and for allocations larger than a /24 block you would have to breakdown your /17 into 128 sets of /24 and use individual sets for reverse DNS.

  2. The reverse DNS has nothing to do with a netmask. It is just the PTR of an IP.

    So the answer is: The same!
