IPAM Tools

IP address and subnet management with visual tools and calculators

Overview

The IPAM (IP Address Management) module gives your team a single source of truth for all IP allocations, subnets, and VLAN assignments across your network. It integrates with device discovery to automatically populate known allocations and flags conflicts.

Managing Subnets and VLANs

Subnets are organized in a hierarchical tree: Supernets → Subnets → IPs.

Adding a subnet

  1. Navigate to IPAM → Subnets.
  2. Click Add Subnet and enter the network address and prefix length (e.g. 10.10.0.0/24).
  3. Optionally assign a VLAN ID, site, and description.
  4. Save. The subnet appears in the tree and its /32 IPs become individually trackable.

VLAN mapping

Each subnet can be associated with one or more VLAN IDs. This mapping is visible in the VLAN view under IPAM → VLANs, which shows all VLANs and their associated subnets in a table.

Tip: Import existing subnets in bulk using the CSV import tool at IPAM → Import. The template includes columns for network, mask, VLAN, site, and description.

IP Allocation and Tracking

Within each subnet, individual IP addresses can be marked as Reserved, Allocated, or Available.

States

  • Available - not assigned to any host.
  • Reserved - held for future use or infrastructure (e.g. gateway, broadcast).
  • Allocated - assigned to a device with hostname and owner recorded.
  • Discovered - found via scanner but not yet manually allocated.

Allocating an IP

  1. Open a subnet and click an available IP address.
  2. Fill in hostname, owner/team, device type, and notes.
  3. Click Allocate. The IP is now tracked and searchable.

Conflict detection

If the scanner discovers a device at an IP that is marked Available or Reserved, a conflict alert is raised in the IPAM → Conflicts view for review.

Using the Subnet Calculator

The built-in calculator helps you plan subnetting without external tools.

Features

  • Enter any network/prefix and view: network address, broadcast, usable range, wildcard mask, and host count.
  • VLSM (Variable Length Subnet Masking) planner - input required host counts per subnet and get optimal prefix lengths.
  • Supernet calculator - enter multiple subnets and find the smallest enclosing supernet.
  • IPv6 prefix calculator with full expansion and compression.
Input: 192.168.10.0/26 Network: 192.168.10.0 Broadcast: 192.168.10.63 First host: 192.168.10.1 Last host: 192.168.10.62 Hosts: 62 Wildcard: 0.0.0.63

IP Scanner and Discovery

The scanner pings a subnet range and performs reverse DNS lookups to discover active hosts.

Running a scan

  1. Go to IPAM → Scanner.
  2. Enter a subnet (e.g. 10.20.5.0/24) or a range (e.g. 10.20.5.1-10.20.5.100).
  3. Choose scan options: ICMP ping only, or ICMP + TCP port probing (ports 22, 80, 443).
  4. Click Scan. Results populate in real time.

Reconciling results

After a scan, use the Reconcile button to import discovered hosts into IPAM as Discovered entries. You can then bulk-approve or reject each entry, and assign hostnames and owners.

Tip: Schedule recurring scans under IPAM → Scan Schedule to keep your records automatically updated.
