How can I configure rDNS / PTR for my VPS IP?

Hello,
I need to assign server.juxwave.com as the rDNS for my VPS IP (95.216.50.84).
I already created the corresponding A record.

Is there any way to do this manually, or can an admin assist me?

Thanks.

You need to register for rDNS from the panel of the company from which you purchased the vps server.
