You can set Reverse DNS for your IPv4/IPv6 address very easy by following the following steps.
Important: VPS'es ordered before 2020 can only have Reverse DNS records set through our VPS-Panel.
1) Navigate to “Services” ⇒ “My Services” in your client area, and select the related VPS.
2) Allow 5 seconds to generate the page with all your VPS details.
3) You'll notice a “Reverse DNS tab” is shown in the menu of the VPS-Panel.
4) Select your IPv4/IPv6 address, and enter the preferred Reverse DNS entry in the “Domain Name” field.
5) Click on “Add Reverse DNS” to apply your DNS record.
Note;
A) In case your IPv6 address isn't listed, you need to navigate to the “Settings” tab first and add the IP address at “Manage IPv6 Subnets”. Please make sure when adding the IPv6-address to write it in full.
B) As with all DNS changes, depending on the Time To Live (TTL) it may take a few minutes up to several hours before your changes are visible.
