Open DHCP Server
Open DHCP Server provides Dynamic Host Configuration Protocol service for assigning network addresses.
What Open DHCP Server is
Open DHCP Server provides Dynamic Host Configuration Protocol service for assigning network addresses. It supports static hosts and dynamic DHCP ranges, with as many as 125 ranges on one server, and can serve multiple zones. BOOTP and relay agents are supported. DHCP options can be assigned globally, to a range or to a client; values may be entered as strings, IP addresses, hexadecimal strings or byte arrays without defining option types. Ranges can be filtered by MAC ranges, vendor options and user options. For resilience, the server supports replicated fail-safe operation and DHCP failover. Lease status is shown on an HTML page that refreshes automatically. The project describes the software as using little memory and having low CPU and executable size. It is free, open-source software released under the GNU General Public License, and the repository includes a GPL-2.0 license. It is listed for Linux and self-hosted use, with on-premises deployment. The project says it is suited to experts as well as small and home setups, including people without DHCP protocol knowledge. The listed plan costs nothing.
