Originally created by @xxixo on GitHub (Dec 12, 2025).

NetBox version

v4.4.8

Feature type

Change to existing functionality

Proposed functionality

Currently, the IPAddress model supports only a single dns_name value (string field).
I propose extending this design to enable assigning multiple DNS names to a single IP address.

Use case

Many operational environments map multiple DNS records to the same IP address, such as:

  • multiple A-records for applications (e.g., www.example.com, api.example.com);
  • multiple service-specific hostnames pointing to one reverse proxy or load balancer;

Database changes

Modify the IPAddress model by replacing the existing dns_name field (string) with a list-type field capable of storing multiple DNS names.

  • Convert the current dns_name (CharField) to ArrayField(CharField)

External dependencies

No new external dependencies are required.

The proposed functionality is beyond the intended scope of the IPAddress model. If you need to manage more complex DNS records, consider a plugin such as netbox-plugin-dns.
