when testing the reverse forward DNS using a tool, I got this:
FCrDNS test result:
x.x.x.x resolved to x.x.x.x.in-addr.arpa;
x.x.x.x.in-addr.arpa unresolved;
rDNS is NOT forward confirmed.Generic PTR record test result: x.x.x.x.in-addr.arpa looks like generic.
With other tool, I got this:
Reverse DNS to x.x.x.x
IP address: x.x.x.x Reverse DNS: OK x.x.x.x.in-addr.arpa
Reverse DNS Authenticity: Warn Could be forged: Hostname
‘x.x.x.x.in-addr.arpa’ does not exist Reverse DNS
Domain: x.x.x.x.in-addr.arpa
Can you give me some hints about how to correct them?
I manage both the host computer and the DNS server, which are different machines.
