Subnet, VLAN and IP allocation: lightweight, multi-zone and vendor-agnostic, built for OT networks where an address stays put for decades. Paired with narrowin Explorer, it shows a live diff between your plan and what the network actually contains.
Addressing is the source of truth your whole network depends on. Keep it in a spreadsheet and you're running critical infrastructure on a guess.
Purpose-built for operational networks, where IP addresses are infrastructure, not just database entries.
Live validation shows exactly where your documentation has diverged from the live network, down to the row.
Addresses assigned for 10–20 years, strict change control, zero tolerance for conflicts. Built for this, not adapted from an IT tool.
Before you touch the network, confirm the plan is accurate. The live diff surfaces the discrepancies that would otherwise bite mid-change.
Demonstrate accurate address documentation for ISO 27001, IEC 62443 and similar. Full change history; exports ready for auditors.
Integrating two networks? Import both address spaces, detect overlaps, plan migrations. Utilization makes consolidation visible.
Bring an existing Excel or CSV. IPAM validates it against reality and keeps it current. Most migrations finish in hours, not weeks.
Manage the plan, check it against the live network, and stay light enough that a small team keeps it current.
IPAM is the addressing layer of narrowin Explorer. On its own it is a modern, lightweight IP manager; connected to Explorer it becomes a live diff: your plan against the network Explorer actually discovers. It has its own page because an addressing problem deserves a direct answer, but in practice the two are deployed together.
Getting started is simple, whether you run IPAM on its own or paired with Explorer for the live diff.
Bring an existing Excel or CSV. IPAM validates the data and flags conflicts and duplicates. Hours, not weeks.
With Explorer connected, IPAM continuously compares your plan against the discovered network state.
VLAN mismatches, address conflicts and unplanned subnets surface the moment they appear.
Resolve a discrepancy in one click: update the plan to match reality, or flag it for investigation.

Live validation. Most IPAM tools are documentation databases: they store what you tell them. narrowin IPAM continuously compares your plan against the network Explorer actually discovers, so discrepancies surface before they cause problems. It is also light enough for a small OT team to keep current.
Both, in effect. IPAM is the addressing layer of the Explorer family and is normally deployed with it: that pairing is where the live diff comes from. It has its own page because an addressing problem deserves a direct answer.
Yes, standalone, as a modern, lightweight IP manager: import, allocate, track utilization. The live diff needs Explorer's discovery data; add Explorer later and it switches on.
Excel or CSV import with validation. IPAM flags conflicts and duplicates on import and brings in clean records. Most migrations finish in hours.
Yes, full IPv4 and IPv6 prefix and address management, side by side.
IPAM tracks DHCP ranges and can import lease data. Direct DHCP-server integration varies by vendor. Talk to us about your environment.
