This is RedHat Linux 8. DNS forward lookup is working fine.
I get proper responses for names anywhere on the internet.

When I type in an ip address however I get no response. Is this a valid test for redhat reverse lookup or is there another better way.

As far as I can tell my revers lookup zone is fine.

it all depends if your redhat box is authorative for that ip class
to find out run a whois on one of you ip address

whois -h whois.arin.net x.x.x.x
replace arin.net wich ripe.net or apnic.net depending on you
location.

if you are auth. for that class and you have no response from
your dns then your dns is not working properly.

if you are not auth. for that class, try to do a lookup using your
server, i.e.

host x.x.x.x my.dns.server

tc
