Oblimap — Intelligent network cartography & IPAM

How it works

Scan, discover, map — continuously

One probe per network site. It runs ARP scans and ping sweeps on a configurable schedule, pushes every new discovery to the central server, and flags any change since the last scan.

Lightweight probe — no agent on hosts

Deploy one probe binary per site on Windows, Linux or macOS. It scans the local network autonomously — no software to install on monitored devices.

Multi-method discovery

ARP scan for local subnet devices, ICMP ping sweep for reachability, mDNS/Bonjour for hostnames. Combines all three for maximum coverage with zero configuration on the target hosts.

Persistent IPAM database

Every discovered IP and MAC address is stored with its first-seen and last-seen timestamps. Historical data stays intact — you can trace when any device appeared or left the network.

Device renaming & labelling

Assign a meaningful name to any device directly in the IPAM. Labels and custom names persist across scans — an IP may change, but your name for the device stays in the record.

Change detection & alerts

New device on the network? A MAC address moved to a different IP? A device went silent? Oblimap spots it and raises an alert — keeping you informed of every topology change.

MAC vendor lookup

MAC addresses are automatically resolved to their manufacturer using the OUI database. Instantly know whether a device is an Apple, Cisco, Dell or unknown — without logging into it.

IPAM Dashboard

Every device, every site, one view

The central dashboard lists all discovered devices across all sites. Filter by site, subnet or status. Rename, label and annotate directly from the table.

Network map

Visual cartography of your site

A graphical view of every discovered device, laid out by subnet. See relationships, spot unknown devices and drill into any node for its full discovery history.

▸ One map per site, all sites accessible from one dashboard
▸ Colour-coded device status (up / new / gone / unknown)
▸ Click any node — IP, MAC, vendor, name, history
▸ Rename and label directly from the map

Probe configuration

One binary, one command

Configure the subnet(s) to scan, the scan interval and the central server endpoint. The probe registers itself, begins scanning and pushes results automatically.

Configurable scheduleMulti-subnet Custom site labelsNo root required

▸ One probe covers one or multiple subnets on the same site
▸ Scan interval configurable per probe (e.g. every 5 min)
▸ Probes push outbound only — no inbound ports on the server

Quick deploy

Up in 60 seconds

One command for the central server. Then drop a probe on each network site with a single line — they auto-register and start scanning.
