The record

Purpose: Monsoon is an open-source platform that combines a DHCP server and IP address management in one Go binary.
DHCP: It supports DHCPv4 and DHCPv6, including features such as relay information, prefix delegation, and dynamic DNS updates.
IPAM: Its IPAM features include subnet hierarchy, CIDR tools, capacity planning, network discovery, conflict detection, and an audit trail.
Dashboard: The embedded web dashboard includes subnet, IP address, lease, reservation, discovery, audit, and settings views.
APIs: Monsoon provides REST and gRPC APIs, WebSocket events, and an MCP server.
Integrations: The project lists Slack and generic JSON webhooks, Prometheus metrics, and migration tools for ISC DHCP, Kea, phpIPAM, NetBox, and CSV.
Storage: It uses embedded storage with a B+Tree index, write-ahead log, periodic snapshots, and crash recovery.
Security: The README describes local authentication, configurable TLS, rate limits, temporary lockouts, secure session cookies, defensive response headers, and auditing of security-related authentication events.
Authentication limit: The current build supports local authentication only; LDAP configuration is not supported by the current binary.
High availability: HA is described as basic active-passive heartbeat and lease synchronization for controlled environments, with limited-scope operational support.
Discovery limit: Discovery currently supports scheduled or manual scans and limited active probe enrichment; true passive rogue-DHCP sensing is not implemented.
Platforms: The README lists Linux, FreeBSD, macOS, and Windows support; DHCP is limited on macOS and Windows.
Deployment and audience: Monsoon is self-hosted, with systemd and Docker deployment examples; multi-tenant SaaS is out of scope for v1.
License: The repository states that Monsoon is licensed under Apache 2.0.
