NetBox version

v2.10.8

Feature type

Change to existing functionality

Proposed functionality

Add parent prefixes information to host vars in ansible nb_inventory plugin.

Use case

We use netbox prefix roles to define purpose of subnet, for example LAN, KVM, Docker. Once installing daemons (for example sshd) using ansible on linux machines, we define prefix role for address on which sshd should listen and querying netbox to find corresponding IP. This involve two steps: get prefixes with certain name, and get all hots IP's which are in these prefixes.

It would be great to include parent prefix for all host IP's in nb_inventory plugin:

{
  "interfaces": [
    {
      "cable": {
        "id": 1,
        "label": "",
        "url": "http://xxx.yyy.com/api/dcim/cables/1/",
        "ip_addresses": [
          {
            "address": "10.0.0.2/24",
            "created": "2021-03-25",
            "prefixes": [
              {
                "id": 1,
                "url": "http://xxx.yyy.com/api/ipam/prefixes/1/",
                "family": {
                  "value": 4,
                  "label": "IPv4"
                },
                "prefix": "10.0.0.0/24"
              }
            ]
          }
        ]
      }
    }
  ]
}

This repository is for NetBox itself. You'll need to submit any feature requests for the Ansible inventory plugin to that project.
