Two RFC2317 Questions

[Barry Finkel]

I have removed the "/25" from my zone definition, as others suggested.
and I added the two swbell nameservers.  Here are my named.conf
file and reverse zone:

-----
zone "0.241.60.216.in-addr.arpa." {
        type master;
        file "able.rev";
};
-----
$TTL 86400 ; default time to live is 1 day
$ORIGIN 0.241.60.216.in-addr.arpa.
;$INCLUDE named.local
;       named.soa
;       define start of authority, name servers and loopback
;       As per BIND 4.9 operations guide, serial number format is now
;               "YYYYMMDDNN" where NN is the daily sequence number.
;
@               IN      SOA     dns0.anl.gov. hostmaster.anl.gov. (
                                2002041001      ; Serial

;
17      IN      PTR     csgax.able.anl.gov.
<<I have omitted the rest of the zone.>>
-----
For the DNS registration   216.60.241.17 <===> csgax.able.anl.gov.

    I can query the nodename; I get a the IP address in response.
         216.60.241.17

    I query the IP address; I get the CNAME in response.
         17.0.241.60.216.in-addr.arpa.

    I query the CNAME, and I get "NOERROR, ANSWER: 0" in response.
    Is there something else wrong with my configuration?
