unable to add reverse map from 10.1.168.192.in-addr.arpa. to tftpadmin-desktop.bbnl.i


Hi,
I am trying to learn dns on my ubuntu 8.04 box and I presume it is working. I have set up the auto update of clients to the dns.
When the client tries to register is see the following error in the syslog

unable to add reverse map from 10.1.168.192.in-addr.arpa. to tftpadmin-desktop.bbnl.i
Not sure where i am going wrong. If somebody can help me out here, that will be a great help.

the configurations are as follows

tftpadmin@bbnldmn:/etc/bind$ cat named.conf.local
//
// Do any local configuration here
//
key DHCP_UPDATER {
algorithm HMAC-MD5.SIG-ALG.REG.INT;

# Important: Replace this key with your generated key.
# Also note that the key should be surrounded by quotes.
secret "4zK3Lgn1xcJ4dysiyT9F5w==";
};
// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";
zone "bbnl.in" IN {
type master;
file "/var/lib/bind/bbnl.in.db";
allow-update { key DHCP_UPDATER; };
};
zone "0.168.192.in-addr.arpa" {
type master;
file "/var/lib/bind/rev.0.168.192.in-addr.arpa";
allow-update { key DHCP_UPDATER; };
};

'ignore client-updates' probably won't help
