DDI - IPAM

After DHCP is configured under DDI, IP Address Management (IPAM) becomes available for that DHCP server.

From DDI → IPAM, the system lists all configured DHCP servers. Selecting a server redirects to the IPAM page, where all discovered and managed IP structures are displayed.

All scope and IP related information displayed in IPAM is fetched directly from the configured DHCP server IP.

This includes:

• Total scopes

• Total IPs

• Available IPs

• Reserved IPs

• Excluded IPs

• Held IPs

• Lease information

IPAM does not calculate these values independently. The DHCP server remains the source of truth.

In the IPAM view, you can see:

• Containers

• Networks (Ranges)

• DHCP Scopes

Each entry shows its CIDR range, utilization, status, title, and description. This provides full visibility into how IP space is organized and consumed on the selected DHCP server.

Using the Actions menu on any container, range, or scope, you can:

• Edit network or scope properties

• Create or manage DHCP failover

• Delete a scope or range (based on permissions)

Inactive Scope Status:

An Inactive scope indicates one of the following conditions:

• The scope has been removed from the DHCP server

• The scope exists but is in an inactive state on the DHCP server

Inactive scopes:

• Remain visible in IPAM for reference

• Do not allocate IPs

• Are excluded from utilization calculations

• May require cleanup or re activation on the DHCP server

From the Create New option, you can:

Create Network:

• Defines a new IP range

• The range can later be converted into a container if needed

Create DHCP Scope:

• Select an network

• Enter scope details such as start IP, end IP, gateway, DNS servers, lease time, and status

• On creation, the scope is pushed to the DHCP server and reflected in IPAM

DHCP Failover:

From the IPAM page, click Manage Failover to open the DHCP Failovers screen.

1. Click Add Failover

Scope Selection

• Select one or more available DHCP scopes that should participate in failover

• Click Next

Partner Server

• Enter the partner DHCP server IP address

• This server will act as the failover peer

• Click Next

Configuration

• Provide a failover name

• Configure general settings such as max client lead time

• Optionally enable authentication and auto state transition

• Select the failover mode

  • Load Balance

  • Hot Standby

• Click Create

Once created, the failover configuration is listed with its status and associated scopes. This ensures DHCP continuity if one server becomes unavailable.

Edit Failover

• Modify failover settings such as mode, partner server, or timing parameters

• Changes are synced directly to the DHCP server

Delete Failover

• Removes the failover relationship from the selected scopes

• DHCP servers revert to standalone operation

Add Scope to Failover

• Additional DHCP scopes can be added to an existing failover configuration

• Ensures high availability for newly added scopes

All failover changes are logged and reflected in IPAM after refresh.

Open Network and Scope Visibility:

From the IPAM networks list, clicking Open Network displays all associated scopes under that network.

For each scope, the system shows:

• Total IP count

• Available IPs

• Assigned or claimed IPs

• Excluded IPs

• Reserved IPs

• Held IPs

These values are displayed as summary cards at the top for quick visibility.

IP Address Level Actions:

Clicking into a specific DHCP scope opens the IP address view, where every IP in the range is listed with its current status.

Each IP can have one of the following states:

• Available

• Reserved

• Excluded

• Assigned or Claimed

Selecting an individual IP opens the IP Properties panel, from where you can perform actions such as:

1. Create DNS Record:

This action allows you to create a DNS record for the selected IP address.

Purpose
Associates a hostname with the IP address in the configured DNS zone.

How it works

• The selected IP address is auto populated

• Admin selects the Primary DNS Zone

• Provides the Hostname

• Selects the Record Type (A record by default)

• Configures TTL value

• Adds an optional Comment

Result

• DNS record is created on the DNS server

• IP is now resolvable via DNS

• Action is logged and visible in IP history

2. Manage DHCP Pools:

This option opens the DHCP pool management view for the selected network.

Purpose
Controls how IP addresses are distributed within the DHCP scope.

Capabilities

• View the full DHCP pool range

• See all existing exclusions within the pool

• Add new exclusions by defining start and end IPs

• Modify or remove existing exclusions

Behavior

• Excluded IPs are removed from DHCP assignment

• Excluded IPs are marked as Excluded in IPAM

• Changes are synced directly to the DHCP server

3. Manage Exclusions:

This action is used to exclude specific IP addresses from DHCP assignment.

Purpose
Prevents DHCP from leasing selected IPs.

How it works

• Select a specific IP range to exclude

• All IPs within the selected range are marked as Excluded

• IP status changes to Excluded

• DHCP server will not allocate this IP

Note

• Excluded IPs do not support DHCP reservations

• For excluded IPs, Manage DHCP Reservation is not available

4. Find Next Free IP:

This action locates the next available IP in the scope.

Purpose
Quickly reserve the next unused IP address.

Scope Level:

For DHCP scopes:

• Find Next IP selects the next available IP sequentially

• Find Random IP selects any available IP within the scope

• Selected IPs are placed in Held state

• Held IPs can be released back to Available if not used

• For scope level IPs, administrators can:

  • Claim IP

  • Manage DHCP Reservation

Network Level:

For network level IPs:

• Only Claim IP is available

• DHCP reservation options are not shown at the network level

This ensures DHCP reservations are managed only within scopes.

Release Option

• Held IPs can be released

• On release, IP returns to Available state

5. Find Random Free IP:

This action selects a random available IP from the scope.

Purpose
Useful for non sequential or load distributed allocations.

Scope Level:

For DHCP scopes:

• Find Next IP selects the next available IP sequentially

• Find Random IP selects any available IP within the scope

• Selected IPs are placed in Held state

• Held IPs can be released back to Available if not used

• For scope level IPs, administrators can:

  • Claim IP

  • Manage DHCP Reservation

Network Level:

For network level IPs:

• Only Claim IP is available

• DHCP reservation options are not shown at the network level

This ensures DHCP reservations are managed only within scopes.

Release Option

• Held IP can be released back to available pool

6. Ping IP Address:

This action tests reachability of the selected IP.

Purpose
Verify if the IP address is currently reachable on the network.

How it works

• Sends ICMP ping request

• Displays success or failure status

Use case

• Validate if an IP is already in use

• Troubleshooting connectivity issues

7. View History:

This action displays the full activity log for the selected IP.

What it shows

• Status changes (Available, Reserved, Excluded, Held, Claimed)

• DHCP sync actions

• DNS creation or deletion

• System or user initiated changes

• Timestamp and action source

8. Claim IP Address:

This action assigns an IP to a specific client.

Purpose
Manually allocate an IP to a device or service.

Required fields

• Client Identifier (MAC address)

• Optional hostname

• Optional comment

Result

• IP status changes to Assigned or Claimed

• IP is no longer available for DHCP allocation

• Change is synced to DHCP server

9. Manage DHCP Reservation:

This action creates or edits a DHCP reservation.

Purpose
Ensure a specific client always receives the same IP address.

Capabilities

• Define reservation method (Hardware Address or Client ID)

• Set reservation type (BOOTP or DHCP)

• Assign hostname and description

• Update or delete existing reservations

Availability Rule

• This option is not available for excluded IP addresses

Export Data (CSV):

This option exports IPAM data into a CSV file.
