Is my DNS set up properly for reverse lookups?

Thank you, Barry, I really appreciate the assistance. Please pardon one
last request... OK, so PTR records can be listed for multiple domains. My
single reverse zone file looks like this:
@ IN SOA firstdomain.com. hostmaster.firstdomain.com. (
1999050900 ; Serial
8H ; Refresh
2H ; Retry
1W ; Expire
1D ) ; Minimum
NS foo.firstdomain.com.
444 PTR foo.firstdomain.com.
444 PTR www.firstdomain.com.
If, as you suggest that this is potentially confusing, is there a better way
to do this?
The SOA statement in this file references only firstdomain.com. Is that a
problem?
What is the impact of just deleting the reverse lookup record for
seconddomain?
And, how can I test the reverse lookups?
Thanks again.
Tim
