Can't get reverse dns working

Question

I've set up bind9 before but now I apparently made a misconfiguration somewhere & I don't see it. DNS is working fine, reverse DNS not. I know I have to reverse the IP range to get it working. Underneath my config. Can some kind soul show me where I messed up?

/etc/bind/named.conf.default-zones

// prime the server with knowledge of the root servers
zone "." {
    type hint;
    file "/etc/bind/db.root";
};

// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912

zone "localhost" {
    type master;
    file "/etc/bind/db.local";
};

    zone "127.in-addr.arpa" {
    type master;
    file "/etc/bind/db.127";
};

zone "0.in-addr.arpa" {
    type master;
    file "/etc/bind/db.0";
};

zone "255.in-addr.arpa" {
    type master;
    file "/etc/bind/db.255";
};

zone "10.168.192.in-addr.arpa" in {
    file "/etc/bind/db.10.168.192.in-addr.arpa";
    type master;
    check-names ignore;
};

zone "XXX.local" in {
    file "/etc/bind/db.XXX.local";
    type master;
    check-names ignore;
};

Huge thanks in advance,

I think you might be missing your NS record(s) in the reverse zone file (I couldn't see the "IN" bit). Also, you probably don't need to pad the last octect out with zeros.
