ANTlabs Tru'IP vs Open DHCP Server

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.

Open DHCP Server is free, open-source software that provides Dynamic Host Configuration Protocol service on Linux and self-hosted, on-premises deployments. It assigns addresses through static hosts and dynamic DHCP ranges, supporting up to 125 ranges on one server. Multiple zones can run on a single server, with BOOTP and relay-agent support. DHCP options may be set globally, for a range, or for an individual client, using string, IP, hexadecimal-string, or byte-array values without defining option types. Ranges can be filtered by MAC ranges, vendor options, and user options. Replicated fail-safe operation supports continuity, while lease status appears on an auto-refreshing HTML page. The project describes low CPU use, small executable size, and very low memory requirements. It is released under the GNU General Public License, with a GPL-2.0 repository license. The project says it suits experts and small or home deployments, including people without DHCP protocol knowledge.
