DNS PTR record when domain on shared IP address
- by Marco Demaio
Hello,
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 -> IP
mydomain.com A -> IP
ftp.mydomain.com A -> IP
mail.mydomain.com A -> IP
mydomain.com MX(10) -> IP
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
