I own a typical shared IP hosting plan and domain. I can modify the DNS of the domain from the control panel. The mailserver shares the same IP address, so my typical DNS config is:
www.mydomain.com A -> myIP mydomain.com A -> myIP ftp.mydomain.com A -> myIP mail.mydomain.com A -> myIP mydomain.com MX(10) -> myIP
I read some Q&A on this site where they suggest to add PTR record mainly for mailserver.
I would like to add PTR record to my domain, I have got two questions:
1) can PTR record be added even if the hosting/mailserver are on a shared IP address? Or do I need a dedicated IP.
2) How do I setup PTR record, I mean does it look like A record:
mydomain.com (PTR) -> myIP
