classless in-addr.arpa delegation

[dleefy]

I am facing problem to delegate reverse lookup....
I am trying to implement classless in-addr.arpa delegation....to transfer the adminstration of the zone file to respective clients, rather than the ISP.
I have followed all the instructions from RFC 2317: Classless IN-ADDR.ARPA delegation, but still got the following error....

This is what i did....

on the ISP side..
===========

1. in 56.121.203.rev file,
-----------------------------

-------------------------

zone "56.121.203.in-addr.arpa" in {
type master;

on the client side..

};


when running nslookup at ISP named server, I got these error....

1. in ISP nameserver
-------------------------
> set type=ptr

** server can't find 1.56.121.203.in-addr.arpa.: SERVFAIL
