One static IP address and reverse lookup

I have one static IP address on a linux
box with Bind 8.
I have a number of domains. Happily,
bind works, and serves the zones for
my domains and granitecanyon is functioning
fully as zone slaves.
My IP address is 209.21.191.17
The way I have things set up, I have one
and only one A record among all my zones,
acme.acmeconscience.org
All my other zones consist of CNAMES which
point to acme.acmeconscience.org including
the CNAME for my nameserver ns.acmeconcscience.net
My MX records use acme.acmeconscience.org as
the lowest value MX record.
The domains that are set up are
acmeconscience.org (the one with the A record)
acmeconscience.net (the one with the registered name server)
bannerclub.com
creativepeople.org
cybergood.net
cybergood.org
cybergod.org
What should I do with regards to obtaining
delegation for my static IP address.
Clearly my ISP has the reverse lookup zone
191.21.209.in-addr.arpa
The contents of that zone is correctly
$ORIGIN 21.209.in-addr.arpa.
191 86400 IN SOA ns.mercurian.com. celtic.celticweb.com. (
2000010501 28800 7200 604800 86400 )
86400 IN NS ns.mercurian.com.
86400 IN NS auth01.ns.harvard.net.
$ORIGIN 191.21.209.in-addr.arpa.
1 86400 IN PTR cisco2513.celticweb.com.
12 86400 IN PTR roger.celticweb.com.
14 86400 IN PTR usagateway.wonderbox.com.
15 86400 IN PTR brennick.com.
17 86400 IN PTR acme.acmeconscience.org.
19 86400 IN PTR namebears.celticweb.com.
2 86400 IN PTR ns.mercurian.com.
25 86400 IN PTR svaha.com.
3 86400 IN PTR celticweb.com.
4 86400 IN PTR pagesentry.celticweb.com.
40 86400 IN PTR linux.brennick.com.
5 86400 IN PTR pop.celticweb.com.
6 86400 IN PTR ntserver.celticweb.com.
8 86400 IN PTR www.newgrange.net.
9 86400 IN PTR smtp.celticweb.com.
Is it possible for me to have the delegation of
17.191.21.209.in-addr.arpa
That way I could add reverse lookups for multiple
A records for my one static IP address.
Or is it in principle best that for each IP address
it is best to have 1 A record and one corresponding
PTR record, and that's it.
