Track allocations, monitor utilization, flag conflicts. Saves locally in your browser — no signup, no server.
Full IP Address Management products (Infoblox, BlueCat, NetBox) are powerful and expensive. For small teams that just need to track "who has which subnet" without standing up a server, a local inventory is plenty. This IPAM tool stores everything in your browser via localStorage — no account, no server, no leak. Export to CSV when you want to back it up or share with the team.
It tracks allocations, surfaces conflicts as you add them, lets you tag and filter, and renders utilization. For full visual context, the visualizer reads from the same inventory and renders the topology.
For team-scale workflows that go beyond a single user's localStorage, workspace projects let you save and share full network designs via URL. Use IPAM for inventory and conflict detection; use Workspace for plan-and-iterate-with-collaborators.
The IPAM for small teams article covers the workflow patterns this tool was built around. If conflicts keep cropping up across cloud accounts, multi-cloud CIDR planning walks through how to prevent them at the design stage. For dealing with conflicts that have already shipped to production, see troubleshooting overlapping CIDRs.
IP Address Management (IPAM) tracks who owns which subnet across your network. You need IPAM when you have more than a handful of subnets across multiple environments, regions, or VPCs — at that point mental tracking breaks down. IPAM detects conflicts when you add new allocations, shows utilization, and exports inventory for handoffs.
This is a browser-side IPAM-Lite tool: all inventory lives in your browser's localStorage, no server, no signup. It is designed for small teams that need conflict tracking and CSV export without standing up infrastructure. Enterprise tools like Infoblox, BlueCat, and NetBox offer more features (DHCP integration, RBAC, audit logs) but require deployment and ongoing maintenance.
No. The IPAM tool stores everything in your browser's localStorage. No data is transmitted to our servers or any third party. To back up or share your inventory, use the CSV export.
Yes. The import button accepts a CSV file with columns for CIDR, name, owner, status, utilization, tags, and notes. The tool validates each row and surfaces any conflicts with existing entries before importing.
