Description

The ReverseDNS module for WHMCS allows your clients to fully manage rDNS (PTR) records for their virtual machines, dedicated servers, or entire IP address space directly from the client area.

This module uses PowerDNS as the backend and supports multi-server setups, meaning different reverse zones can be hosted on different DNS servers — all managed seamlessly within a single service.

Key Features:

• Full rDNS management via client area

• PowerDNS backend integration

• Multi-server support for reverse zones

• Supports both "Dedicated IP" and "Additional IPs" fields

• Subnet (CIDR) management support

• Solves the lack of native rDNS management in WHMCS

This module provides a complete solution for reverse DNS control in WHMCS.

⚠️ Important:
In the first version of the module, rDNS management for IPv6 addresses is not supported.
Only IPv4 reverse DNS records can be managed at this time.

Product Configuration

Add new product to WHMCS

System Settings->Products/Services->Create a New Product

In the Module settings section, select the "PUQ ReverseDNS" module

In the product settings, you must assign all rDNS zones that should be available for this product.
It is strongly recommended to include all reverse zones for IP addresses that are used in your services — such as virtual machines, dedicated servers, or other offerings.

Important:
If a reverse zone is not added to the product configuration, the client will not be able to manage rDNS records for IPs within that zone.
Those IP addresses will not even be visible in the client area.
In other words, clients can only manage rDNS records for IPs that belong to the zones explicitly added to the product settings. All other IPs will be hidden from view and unavailable for modification rDNS record.

To add a new rDNS zone, click the "Add Zone" button. A popup window will appear where you can enter the required zone details.

Fields to fill:

• Zone
  For IPv4, enter the reverse zone in the format:
  1.168.192.in-addr.arpa — this corresponds to a /24 subnet.

  For IPv6, enter the zone in /64 format like:
  8.b.d.0.1.0.0.2.ip6.arpa

• Server
  Enter the hostname or IP address of the PowerDNS server or Admin PowerDNS panel.

• API Key
  Provide the API key used to authenticate with the PowerDNS server.

These settings allow the module to connect and manage the specified reverse DNS zone.

 

 

To verify the availability of a zone and the connection to the PowerDNS server, use the "Test" button.

When clicked, a modal window will appear displaying the result:

• If the connection is successful, the modal will show a list of records retrieved from the specified zone.

• If there is an error, the modal will display detailed error information, helping you diagnose connectivity or configuration issues.

 

Client Area

Home screen

On the client area homepage of the service, clients will immediately see a list of all IP addresses assigned to their services.

Each IP has an editable rDNS record.
When a client updates a record, the change is instantly applied to the corresponding zone in PowerDNS — no manual action is required.

 

Admin Area

Product Information

In the admin area, under the product management section, you can view a complete list of all client-assigned IP addresses and their corresponding rDNS records.

Just like in the client area, administrators have the ability to edit rDNS records directly from this interface.
All changes are instantly applied to the PowerDNS server.
