Open DHCP Server
What it is
Open DHCP Server provides Dynamic Host Configuration Protocol service for assigning network addresses. It supports static hosts and dynamic DHCP ranges, with up to 125 ranges and multiple zones on a single server. The server also supports BOOTP and relay agents. DHCP options can be set globally, for a range or for an individual client; values can be entered as strings, IP addresses, hexadecimal strings or byte arrays without defining option types. Ranges can be filtered using MAC ranges, vendor options and user options. For resilience, the software supports replicated fail-safe DHCP operation, and lease status appears on an auto-refreshing HTML page. The project describes the server as using little memory and having low CPU and executable size. It is free open-source software released under the GNU General Public License, with a GPL-2.0 license in its repository. Deployment is on-premises on Linux or self-hosted. The project describes it as suitable for experts as well as small or home use, including people without DHCP protocol knowledge. The listed plan costs nothing.
