ANTlabs Tru'IP vs FluxDHCP

ANTlabs Tru’IP combines DHCP, DNS and IP address management for telcos, ISPs, service providers and large network infrastructure teams. DHCP handles IPv4 and IPv6 with dynamic or static assignment, policy-based allocation, lease management and active-active clustering. DNS supports authoritative, recursive and forwarding modes, centralized records, DNS views, DNSSEC and record balancing. IPAM tracks available, reserved and allocated prefixes and shows subnet utilization and duplicate-subnet visibility inside Tru’IP CMS rather than as a standalone appliance. The CMS centralizes cluster configuration, monitoring, reporting, diagnostics, logs and patch maintenance, with REST, WebSocket, API, CLI, SNMP and alert integrations. Security listings include packet-integrity validation, DNSSEC, role administration and audit trails. Physical and virtual appliance deployments are offered. Published tiers include DHCP 5400 capacity up to 30 million prefixes and five million active leases; DNS 5400 lists up to three million records. Pricing is on request.

FluxDHCP is a free, self-hosted DHCPv4 server managed through a web interface. It supports the DHCPv4 message types listed for RFC 2131, from discovery and address requests to acknowledgments, releases and other listed operations. Administrators can define address pools with subnet ranges, gateways, DNS servers, netmasks and lease times, choose sequential or random allocation, and check for overlapping pools. Static MAC-to-IP reservations and per-device DHCP option overrides are supported. Lease records track offered, bound, released and expired states, with automatic cleanup for expired entries. A packet logger records transaction details, direction, raw options, client information and millisecond timestamps. Webhooks can send DHCP events to external services by HTTP POST or GET, with template variables and custom headers. Configuration can be imported or exported as JSON, and imported changes are hot-reloaded. The project is AGPL-3.0 licensed and supports English and Chinese, dark mode and a responsive mobile-friendly interface. It requires Node.js 20 or later; Docker Compose is recommended, and binding UDP port 67 requires root or administrator privileges.
