PTR Record

A PTR (reverse DNS) record maps your service IP back to a hostname, which improves email deliverability and some service checks.

Open the configuration​

  1. Go to the Overview tab of your service dashboard.
  2. Find the Manage PTR Record section.
  3. Click Manage PTR Record.

Manage PTR Record

Steps​

  1. Enter your domain (pre-filled if an existing PTR or CNAME is available).

  2. Create these DNS records:

    • A record points to your service IPv4.
    • AAAA record points to your service IPv6.

  3. Verify propagation with DNSChecker.

  4. Click Update to apply.

Provider notes​

  • DigitalOcean — The system reboots after applying changes. PTR updates can take a few hours due to DNS caching.
  • Other providers — Reverse DNS applies through the provider's own flow, and propagation timing can vary.
