IPClaimCheck

IPClaimCheck is a lightweight web app (with optional desktop agent) that continuously detects and explains IP address conflicts, rogue DHCP servers, and duplicate static assignments across small-to-mid networks. It passively listens via ARP/DHCP/ND signals (and optionally polls switches/routers via SNMP) to build a near-real-time map of “who is claiming what IP” and how that claim is being made. When a conflict appears, it pinpoints the likely source device, the switch port/VLAN (when available), and the blast radius (which hosts are impacted). It also provides a simple workflow to reserve/mark addresses, attach notes, and export evidence for IT tickets. This is a traditional app with AI-assisted diagnostics: the AI component summarizes incidents, suggests probable causes, and recommends next steps, but it doesn’t pretend to magically see what your network blocks.
