IP Address Management (IPAM)

You can now plan, track, and manage IP addresses inside a network with Hudu's new IP Address Management feature! IP Address Management will allow tracking:

• How many IP addresses are inside of a network.
• What the IP addresses are currently doing.
• Details about a network.
• Subnets inside of a network. 

The sections below will guide you through adding a network and managing IP addresses within the network.

Set network defaults from pre-defined lists

• Navigate to the Hudu Admin tab → select IPAM.
• Set a list to choose statuses from.
• Set a list to choose roles from.

Adding a network

• Navigate to a client space.
• Select IPAM from the left-hand sidebar.
• In Networks, Click New.
• Choose Network.
• Enter a CIDR Range. 
• Select a Parent Network (optional).
• Select a Status from a pre-made list (optional).
• Select a Role from a pre-made list (optional).
• Add a Description to show in the table view (optional).
• Add Labels (optional)
  • Visit our article on Labels for more information.
• Add Notes (optional)
  • See our guide on using the Notion-Style editor.
• Click Create or Create and add another at the bottom to save.

Adding subnets

• Navigate to the IPAM section in a client space.
• Click on the parent network you want to add a subnet under (e.g., 10.10.0.0/16).
• Under Subnets, click +New.
• Enter subnet details.
  • The subnet you’re adding must be a valid CIDR block and must fall within the parent network range
• Select Create or Create and Add Another to save.

Adding IP addresses

• Once the network is created, click the + New button in the IP Addresses section.
• Choose the Type of IP Address
  • Single IP
  • IP Range
• Add an IP address for single IP or Start and End IP for IP Range, and choose a status (Assigned, Unassigned, Reserved, Deprecated, etc..).
• Choose asset and FQDN associated with the IP address if it is a single IP.
• Add a Description (optional).
• Add Labels (optional).
• Use the Filter option to find added IP addresses - filter by IP Address, Status or FQDN. 

Adding VLANs

• Navigate to a client space.
• Select IPAM from the left-hand sidebar.
• Choose VLAN or VLAN Zone.
• Enter the VLAN ID/Name.
• If you need to add a VLAN to an existing network:
  • Navigate to the network.
  • Click Edit.
  • Select a VLAN from the dropdown. 

Understanding IPAM structure

Hudu's IP Address Management (IPAM) feature offers a structured approach to organizing and managing network components. Here's how each element is defined and how they interrelate:

Networks and parent networks

• Network: In Hudu, a Network represents a defined IP range, specified using CIDR notation (e.g., 192.168.1.0/24). Networks are the building blocks used to document and manage IP address space.
• Parent Network: Larger networks (e.g., 192.168.0.0/16) can serve as Parent Networks, under which smaller, nested networks can be organized. A parent network's utilization includes the IP addresses in its child networks.

Subnets

Subnets are subdivisions within a network that allow for more granular control and organization of IP address space. When viewing a parent network, all associated subnets are listed, providing a clear overview of the network's structure.

IP addresses

Each IP Address within a Network or Subnet can be individually managed. Hudu allows you to assign statuses to IP addresses (e.g., Assigned, Unassigned, Reserved, Deprecated), associate them with specific assets or Fully Qualified Domain Names (FQDNs), and include additional metadata.

VLANs and VLAN zones

• VLAN (Virtual Local Area Network): A VLAN in Hudu is identified by a unique VLAN ID and can be associated with specific Networks. This association helps in segmenting network traffic and enhancing security.
• VLAN Zone: VLAN Zones are collections of VLANs grouped together based on specific criteria or organizational needs. They allow for the specification of VLAN ID ranges, controlling which VLANs can be added to a particular zone.

Interrelationships

The interrelationship between these components in Hudu's IPAM is hierarchical and modular:

• Parent Networks represent larger CIDR blocks that can be subdivided into smaller networks.
• Networks in Hudu are any defined IP ranges (CIDR blocks) and can be standalone or nested under a parent.
• Subnets are smaller networks nested under a parent network to represent IP address segmentation.
• VLANs can be associated with networks to document traffic segmentation and network isolation.
• VLAN Zones group related VLANs together for easier organization and management.

This structured approach enables efficient management, clear visualization, and streamlined documentation of complex network infrastructures within Hudu.

Global network view

To view networks across all companies, navigate to the Global section of the toolbar. From there, select Networks from the left-hand sidebar to see a list of all available networks. Please note that users in a security group will only see networks according to their assigned permissions.

Networks in the Global view can be filtered by company by clicking Filters in the top right next to the networks search bar.

Integrations that populate IPAM

Some native integrations can sync networks directly into IPAM, so you don't need to add them manually. Synced networks are added to the IPAM section of the Hudu company they're matched to.

• Auvik: Auvik-discovered networks sync into the IPAM section of the matched company unless the Skip Networks option is enabled.
• UniFi OS: Each UniFi network syncs into the IPAM section of the matched company. UniFi-provided devices sync as assets but are not related to the synced network.
• UniFi (self-hosted): Network configurations sync into Hudu unless networks are skipped in the integration settings. Default UniFi networks are filtered out unless they are enabled.

Hudu Radar

Hudu Radar is an optional add-on that scans your clients' networks and automatically documents what it finds in Hudu. When a company uses Hudu Radar, discovered networks are automatically created and kept up to date in that company's IPAM section, so you don't need to add them manually.

Companies using Hudu Radar also get a Map section in their IPAM tab menu. This section shows a network map that Hudu Radar builds and updates automatically.

• The Map section is only available for companies using Hudu Radar.
• Companies that do not use Hudu Radar will not see the Map section in IPAM.
• If a company stops using Hudu Radar, the map is automatically removed.
• Use the zoom controls on the map, or your mouse wheel, trackpad, or a pinch gesture, to zoom in and out.
