Purpose: DacatDHCP combines a DHCP service with a web management interface for configuring address pools, viewing leases, and monitoring service status.
Features: It supports network-interface selection and configuration of address ranges, gateway, DNS, and lease duration.
Lease management: The interface can show assigned addresses and client information, and the latest release adds MAC-to-IP fixed mappings with matching logs.
Platform: The main version supports Windows 10, Windows 11, and Windows Server 2016 or later, with Windows amd64 releases.
Browser support: The management interface supports Microsoft Edge, Google Chrome, and other modern Chromium-based browsers; Internet Explorer 11 is no longer supported.
Security: The management interface listens only on 127.0.0.1, and write endpoints use CSRF and origin checks.
Permissions: Running the application requires administrator privileges.
Limits: It focuses on IPv4 DHCP and does not currently support IPv6 or DHCPv6.
Network scope: The address pool must be in the same subnet as the selected network interface; the product does not support cross-subnet address pools.
Lease persistence: The v1.0.0 release notes say leases are held in memory and are not restored after restart, and that active IP-conflict detection is not provided.
Intended use: The maker describes it for labs, test environments, temporary LANs, small networks, device troubleshooting, and isolated networks.
Support and source: The maker directs users to GitHub for source code, releases, documentation, and issue feedback.
License: The v1.0.0 release is published under the Apache License 2.0.
