On-Prem IPAM with Live Port Mapping

Explore how JANUS combines automated IP inventory, physical switch port attribution, and unified NOC+SOC convergence into an air-gapped network management engine.

Realize deterministic IP inventory without spreadsheets or blind spots

JANUS IPAM delivers an automated, single source of truth for your physical and edge address space. Deployed 100% on-premise on standard Ubuntu Server, JANUS continuously discovers, tracks, and reconciles IPv4 and IPv6 assets across your subnets using native ICMP probing, ARP table inspection, and SNMP sweeps. Operating with zero phone-home telemetry and a flat licensing structure, it eliminates the per-IP licensing penalties and cloud-sync requirements of conventional IP management tools.

✓Continuous scheduled ICMP sweeps and gateway ARP table ingestion
✓Native IPv4/IPv6 dual-stack support across physical and virtual subnets
✓Strictly air-gapped discovery with zero phone-home telemetry
✓Flat predictable licensing with zero per-IP consumption tax

Infrastructure Topology at Your Fingertips: Discover, Track, and Reconcile Subnets at Wire Speed

Maintain authoritative subnet visibility — completely air-gapped and on-premise

Control your core network schema without transmitting internal topology, VLAN layouts, or host inventories to external cloud providers. JANUS runs all subnet calculations, periodic discovery scans, and historical retention entirely within your private boundary, satisfying strict air-gapped and data-sovereignty requirements for defense, utilities, and high-security enterprise enclaves.

01

Use automated discovery to eliminate stale reservations

Replace manual record-keeping with continuous, scheduled network discovery. JANUS sweeps designated CIDR blocks to detect active nodes, mark responsive addresses, and flag abandoned reservations, ensuring your subnet utilization metrics reflect true network state rather than outdated records.

02

Detect rogue hardware and IP conflicts immediately

Guard against addressing discrepancies and unauthorized hardware additions. JANUS tracks MAC-to-IP relationships over time, instantly alerting operators to duplicate IP assignments, MAC address changes on static infrastructure, and unknown devices claiming addresses outside authorized pools.

03

Harness unified entity history and change auditing

Track the complete operational lifecycle of every network address. JANUS logs historical bindings across IP changes, MAC transitions, and switch port migrations, giving engineers an auditable timeline to simplify network troubleshooting, capacity planning, and post-incident forensics.

04

Prioritize capacity planning with real-time subnet metrics

Monitor address pool depletion before outages occur. JANUS provides clear, real-time visualization of subnet saturation, available address buffers, and prefix distribution, enabling network teams to plan route allocations and expand infrastructure based on live network measurements.

05

Bridge IP inventory directly to rapid network control

Turn address visibility into instant operational intervention. Because JANUS links IP records directly to physical switch ports, network operators can pinpoint the exact physical location of a misbehaving or rogue host and initiate port-level remediation right at the hardware layer.
