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.
Guides
The ability to create and manage networks is only available on Hudu Versions 2.28.0 or later.
The sections below will guide you through adding a network and managing IP addresses within the network.
Set Network Defaults From Pre-Defined Lists
The Hudu admin area is accessible ONLY to your organization's admins and super admin users.
- Navigate to the Hudu Admin tab >> select IPAM & Racks.
- Set a list to choose statuses from.
- Set a list to choose roles from.
Visit our Lists article to learn more about creating lists for the Status and Role fields!
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 (optional).
- Click Create or Create and add another at the bottom to save.
Locations can be associated with Networks by editing the asset layout that contains your locations and checking the Use For Locations box. For more information on how to edit Asset Layouts, visit Asset Layouts.
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 to save.
Adding IP Addresses
IP address Must be within network rules for it to validate.
- Once the network is created, click the + New button in the IP Addresses section.
- Add an IP address and choose a status (Assigned, Unassigned, Reserved, Deprecated, etc..).
- Choose asset and FQDN associated with the IP address.
- 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/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.
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.
Additional Abilities
The sections below will serve to introduce additional features associated with IP Address Management.
- Client name.
- The action performed;
- By the user who performed the action;
- or by the IP address from which the action was performed.
- The import feature can be used to import new IP addresses or update the current ones.
- To update current IP addresses, use the export function, make the changes, and reimport the file.
