Problems with classless reverse delegation

[John Oliver]

Yes, I've been Googling... :-)  I think that the ISP that's
authoritative for the addresses in question might be doing something
wrong, but I'm not sure.

I have 209.68.231.0/29  The authoritative DNS server, ns.cts.com,
supposedly has the NS and CNAME records... the hostmaster swears they're
there and correct.  Nothing that I do on my end makes this work, but,
then again, I've *never* made this work :-(  I just haven't really cared
until now.

My named.conf entry:

zone "0-29.231.68.209.in-addr.arpa" {
        type master;
        file "zone/231.68.209.0-29";
};

And the zone file:

[joliver at ns joliver]$ cat /var/named/zone/231.68.209.0-29
$TTL 3600
;0-29.231.68.209.in-addr.arpa.
@               IN      SOA     ns.sdsitehosting.net.
hostmaster.sdsitehosting.net. (
                2003010302      ; serial number
                3600 1200 1209600 3600 )
                IN      NS      ns.sdsitehosting.net.

1               IN      PTR     hosting-gw.home.john-oliver.net.
2               IN      PTR     host2.john-oliver.net.
3               IN      PTR     host3.john-oliver.net.
4               IN      PTR     host4.john-oliver.net.
5               IN      PTR     host5.john-oliver.net.
6               IN      PTR     broadcast.home.john-oliver.net.

One of the reasons why I think the ISP might have things wrong:

[joliver at ns joliver]$ dig @ns.cts.com -x 209.68.231.2

; <<>> DiG 9.2.1rc1 <<>> @ns.cts.com -x 209.68.231.2

And another:

[joliver at ns joliver]$ nslookup 209.68.231.2
Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
