LeaseLens

LeaseLens is a web app (with an optional lightweight desktop collector) that continuously audits DHCP health across mixed environments: Windows DHCP, ISC Kea, dnsmasq, and common router-based DHCP. It ingests lease tables, scope utilization, failover state, and event logs, then highlights the problems that actually cause outages: scope exhaustion trends, rogue DHCP responders, duplicate MAC/IP patterns, misconfigured reservations, and relay-agent inconsistencies across VLANs. Instead of being yet another dashboard, it focuses on actionable alerts with clear blast radius: which subnets, which switches/APs, and which client types are affected. It also produces “change-proof” reports for audits: historical lease utilization, reservation drift, and who/what changed a scope. An AI-assisted assistant is included only for log summarization and root-cause hypotheses, but every claim links back to raw evidence so admins can trust it.
