How to set reverse DNS (PTR)

What this solves

Receiving mail servers and security tools look up PTR (reverse DNS). A correct PTR that matches your hostname improves deliverability and looks professional.

Requirements (important)

1. Pick a hostname (e.g. mail.example.com or vps.example.com)
2. Create an A record: that hostname → your VPS IP
3. Wait a few minutes for DNS to propagate
4. Only then set the PTR

Set PTR in Client Area

1. Log in to Client Area
2. Open your VPS service
3. Open the Reverse DNS tab (or Actions → Reverse DNS)
4. For each IP, enter the new hostname and click Set PTR
5. Re-check with dig -x YOUR_IP +short after propagation

Extra IPs

Each Assigned IPv4 can have its own PTR. Repeat the A-record → Set PTR steps per IP.

When to contact support

If Set PTR fails even with a correct A record, or dig still shows the old value after several hours, open a ticket with the IP and intended hostname.
