Reverse DNS delegation problem

[Kevin Darcy]

Do you have forwarding enabled within the part of your named.conf you 
didn't show? Forwarding would override delegation. In order to cancel 
forwarding for the 10.in-addr.arpa hierarchy, you'd need to add 
"forwarders { };" to the apex zone definition.
