My tests retrieve…
Your IP address 18.104.22.168 is associated with the domain 3(NXDOMAIN) .
Where can I set this in the box itself?
In my box I am hosting only the mailserver (for a couple of domains), I am not hosting the websites.
I found this… https://www.interserver.net/tips/kb/bind-reverse-dns-example-setup/
do you think this is the way to go?
Thanks in advance for any help
