hello,

someone knows how to configure reverse dns on shared ip for a specific domain ?

thank you for help,

regards,
 
You can't really configure reverse dns to resolve differently for one domain. Technically its possible to add multiple PTR records, but its not really recommended and probably wouldn't do you any good. In general, there should be only one reverse dns/ptr record for an ip address.
 
Yes the rDNS record doesn't need to match the actual domain in this case. It only needs to resolve to A domain (which should resolve back to that ip as well). On a DA server this usually is somethine like server.hostingcompany.tld - but it can be whatever domain you want.

Most datacenters/isps handle the PTR records for IP addresses. Theres a big chance adding them in DirectAdmin is not going to work.

For your IP address its ns1.nac.net which answers the PTR request.

edit: the correct term for a PTR record to point to is a FQDN, which consist of 3 parts of a domain (server.domain.tld). Im not sure, but it might be a good idea to make it the same as the FQDN in DirectAdmin, which is also being used in mail.

thank you,

now I setup it to the main domain dedicated server which is solarkit.ca
 
I guess you can change the fqdn at DirectAdmin -> Administrator Settings -> Server's Hostname. Remember that has to be a subdomain of your domain.
 
ok that's good now :

"
Reverse MX A records (PTR) Your reverse (PTR) record:
89.181.123.209.in-addr.arpa -> solarkit.ca
135.0.196.67.in-addr.arpa -> solarkit.ca
You have reverse (PTR) records for all your IPs, that is a good thing.
"

regards
