DacatDHCP vs Subnetly

DacatDHCP combines an IPv4 DHCP service with a web interface for configuring address pools, viewing leases, and monitoring status. The lightweight single-file application bundles the service and management interface. Settings include network-interface selection, address ranges, gateway, DNS, and lease duration. The interface shows assigned addresses and client information, while version 1.0.0 adds fixed MAC-to-IP mappings with matching logs. The main release supports Windows 10, Windows 11, and Windows Server 2016 or later on Windows amd64. Management works in Edge, Chrome, and other modern Chromium-based browsers; Internet Explorer 11 is not supported. The interface listens on 127.0.0.1, and write endpoints use CSRF and origin checks. Administrator privileges are required. DacatDHCP is permanently free and open source under Apache License 2.0. It is intended for labs, test environments, temporary LANs, small networks, troubleshooting, and isolated networks. Address pools must share the selected interface’s subnet. Leases remain in memory after startup and are not restored after restart; active IP-conflict detection is not provided.

Subnetly is a hybrid SaaS DDI platform for DNS, DHCP, IP address management, network discovery, and network visibility. Its dashboard records IP use and ownership, identifies conflicts and orphaned addresses, and can export QBR data. Local agents manage authoritative DNS zones and DHCP scopes, with a SaaS console coordinating records and configurations. Agents scan active network segments using ARP, SNMP, and ICMP to build a hardware asset registry. Subnetly says its AI insights can identify capacity risks and configuration gaps as well as address issues. Deployment options include Docker, Kubernetes/Helm, Windows Server, and a Linux daemon. The company says agents communicate outbound over HTTPS or TLS without open inbound ports or VPN tunnels. REST APIs and monitoring webhooks support third-party automation, though access varies by paid tier. MSP controls cover customer and site separation, technician roles, and audit records. A free plan is available; paid plans start at $49 a month. Starter and Pro include 14-day trials, Business has a 21-day trial, and signup requires no credit card.
