RFC2317 problems

[Ed Sawicki]

My ISP has delegated reverse dns for my subnet (206.190.136.128/28)
to me. They told me to create a "128/28.136.190.206.in-addr.arpa"
zone. I think I've done that with this entry in my named.conf file.

zone "128/28.136.190.206.in-addr.arpa" {
     type master;
     file "206.190.136"
};

The 206.190.136 file contains the following.

$TTL 86400
$ORIGIN 128/28.136.190.206.in-addr.arpa.
@	IN	SOA	ns1.alcpress.com. hostmaster.alcpress.com.
                       (2000032701 86400 3600 345600 86400)
@	IN	ns	ns1.alcpress.com.
129	IN	PTR	ed.alcpress.com.
130	IN	PTR	igor.alcpress.com.
131	IN	PTR	ns.alcpress.com.
<snip>
142	IN	PTR	bay.alcpress.com.

This is not working properly. It's not clear to me whether I
should be able to query my dns server directly so my
troubleshooting abilities are a bit limited. I've read RFC2317
over and over. Is the problem on my side or on my ISP's side?
