reverse problems

[Andi Salimun]

Hello I have strange problem with reverse lookup. I have to perform 
hostname lookup first then reverse will work. In order words is not working.

Here are my configurations snip

db.203.194.218
$TTL 38400
@                       IN      SOA     ns1.shellcafe.com. 
root.ns1.shellcafe.com. (
                18              ; Serial
                8H              ; refresh, seconds
                2H              ; retry, seconds
                1W              ; expire, seconds
                1D )            ; minimum, seconds

         IN      NS      ns1.shellcafe.com.
         IN      NS      ns1.dslglobal.net.

named.conf
zone "130-254.0-255.218.194.203.in-addr.arpa"
         type master;
         file "db.203.194.218";
};


This my dig.
[root at ns1 namedb]# dig d2 +norec +nosea -x 203.194.218.131

I think the ISP have delegated it to my nameserver. But still problems..

Thank for the help in advance.
