Setting a PTR record (also called reverse DNS / rDNS) is done as following:
- Within the controlpanel, navigate to the BladeVPS-page
- Select your VPS and click 'IP Addresses' (left bottomside of the page).
- You can always add a new IPv4-address on this page by clicking 'Request IPv4 addresses' or a IPv6-address by clicking 'Add new IPv6 address'.
- Click the IP-address for which you want to set the 'reverse DNS'.
- Enter the desired reverse DNS-name and click on Modify Reverse DNS to save this record.
When entering a reverse DNS-record it's best practice to enter the hostname of your VPS or the (sub)domain you are sending mail from, for example: server.mydomain.com or mail.mydomain.com. You can also enter a generic reverse DNS-record like 123.456.789.012.in-addr.arpa, but a lot of mailproviders will therefor mark this as too generic and award a higher spamscore to received mail from your IP address.
The PTR-record / reverse DNS will be delegated to our nameservers within minutes. For more information regarding DNS-changes you can consult our FAQ: "Why can't I see my DNS changes?".
