[Pdns-users] Reverse Lookup zone subnetted

We have a /27 block of IP's from our datacenter

Using binddns we listed them like this example  

zone file - 60/
We then added PTR records for it would looks something like

62.60/ IN PTR mail.ourserver.net
63.60/ IN PTR mail.ourotherserver.net

For some reason PowerDNS will not handle the reverse zone as 60/
It will not respond to reverse dns lookup requests. 

If I pull the 60/27. off and use just the first 3 octets of the domain / zone I can get reverse lookup to work, but 
We can't respond to the full /24 as we only have smaller blocks. 

Is there any clean way to only listen on a subnet for reverse DNS lookup?

Any ideas on how to fix this?
