Aliases for a delegated subnet?

Hello;
I recently received notification from UUNET that they had, at our request,
delegated the reverse zone for the block 63.91.79.32 to us. So, being a
good BIND admin, I set out to properly configure this zone, with the
following:
snippet from named.conf:
zone "32.79.91.63.in-addr.arpa." in {
type master;
file "master/public/db.63.91.79.32";
};
The SOA record (db.soa):
$TTL 86400
@ IN SOA ns1.tbred.com. hostmaster.tbred.com. (
2000032810; Serial Number
10800 ; Refresh = 3 hours
3600 ; Retry = 1 hour
604800 ; Expire = 7 days
86400 ) ; Minimum TTL = 1 day
IN NS ns1.tbred.com.
IN NS ns2.tbred.com.
;
and, the zone file itself:
$INCLUDE db.soa
;
35 IN PTR www.texascountrymall.com.
36 IN PTR gw.tsi-tx.com.
This all seems perfectly reasonable, and is working. However, in my
experience, working does not always equal correct. My questions are:
Is it proper to see an alias for '63.91.79.35' to
'35.79.91.63.in-addr.arpa'?
Does it even matter?
Have I badly configured this zone?
[root at ns1 public]# nslookup www.texascountrymall.com
Server: ns1.tbred.com
Address: 198.190.167.16
Name: www.texascountrymall.com
Address: 63.91.79.35
[root at ns1 public]# nslookup 63.91.79.35
Server: ns1.tbred.com
Address: 198.190.167.16
Name: www.texascountrymall.com
Address: 63.91.79.35
Aliases: 35.79.91.63.in-addr.arpa
Thanks in advance for any help offered...
