Doing first time the RFC 2317 style subnet reverse DNS, and have a problem with recursion. When doing a query like "dig @ns1.qnet.fi -x 62.142.217.200" is succeeds from the local network, but outside I get "recursion requested but not available". Our /24 reverse zones work fine, the server knows it's the master and serves ok, like "dig @ns1.qnet.fi -x 62.142.220.5".

Recursion is only allowed for the local networks, but why the server thinks recursion is needed in the first place?

Server ns1.qnet.fi, BIND 9.7.1-P1 W2K3

named.conf:

....
zone "128/25.217.142.62.in-addr.arpa" {
    type master;
    file "named.62.142.217.25-128";
};


;
;    File:      named.62.142.217.25-128
