NetBox plugin for the Kea DHCP server

This plugin allows you to view Kea status, leases and subnets in NetBox. Go directly from a NetBox device/VM to a DHCP lease and back!

Features

• Uses the Kea management API
• View Kea daemon statuses.
• Supports Kea's DHCPv4 and DHCPv6 servers.
• View, delete, export and search for DHCP leases.
• Search for NetBox devices/VMs directly from DHCP leases.
• View DHCP subnets from Kea's configuration.
• REST API and GraphQL support for managing Server objects.

Limitations

• Due to limitations in the Kea management API, pagination is only supported when searching for leases by subnet. Additionally, you can only go forwards, not backwards.

• Searching for leases by subnet ID does not support pagination. This may be an expensive operation depending on the subnet size.

Requirements

• NetBox 4.4 or 4.5
• libdhcp_lease_cmds.so hook library
• libdhcp_subnet_cmds.so hook library

Compatibility

• This plugin is tested with Kea v3.0 with the memfile lease database. Other versions and lease databases may also work.

Installation

1. Add netbox-kea to local_requirements.txt.

2. Enable the plugin in configuration.py

   PLUGINS = ["netbox_kea"]
   

3. Run ./manage.py migrate

Custom Links

You can add custom links to NetBox models to easily search for leases.

Make sure to replace <Kea Server ID> in the link URL with the object ID of your Kea server. To find a server's ID, open the page for the server and look at the top right corner for netbox_kea.server:<Server ID Here>.

Show DHCP leases for a prefix

Content types: IPAM > Prefix

Link URL: https://netbox.example.com/plugins/kea/servers/<Kea Server ID>/leases{{ object.prefix.version }}/?q={{ object.prefix }}&by=subnet

Show DHCP leases for a device/VM interface (by MAC):

Content types: DCIM > Interface, Virtualization > Interface

Link URL (DHCPv4): https://netbox.example.com/plugins/kea/servers/<Kea Server ID>/leases4/?q={{ object.mac_address }}&by=hw

Link URL (DHCPv6): https://netbox.example.com/plugins/kea/servers/<Kea Server ID>/leases6/?q={{ object.mac_address }}&by=hw

Show DHCP leases for a device/VM (by name):

Content types: DCIM > Device, Virtualization > Virtual Machine

Link URL (DHCPv4): https://netbox.example.com/plugins/kea/servers/<Kea Server ID>/leases4/?q={{ object.name|lower }}&by=hostname

Link URL (DHCPv4): https://netbox.example.com/plugins/kea/servers/<Kea Server ID>/leases6/?q={{ object.name|lower }}&by=hostname

You may also use a custom field by replacing {{ object.name|lower }} with {{ object.cf.<your custom field>|lower }}.
