ISC DHCP: Open Source DHCP Server

Open source DHCP server for Linux and Unix-like systems, providing DHCP and BOOTP services for automatic IP address assignment.

What is ISC DHCP?

ISC DHCP is an open-source Dynamic Host Configuration Protocol (DHCP) server software package for Linux and Unix-like systems. It provides network services for automatic configuration of IP addresses and other network parameters on request. Some key features include:

  • Supports both DHCPv4 and DHCPv6 for IPv4 and IPv6 address assignment
  • High performance and scalability to handle networks of any size
  • Granular control over pools, classes, leases, options
  • Distributed and redundant configurations for high availability
  • IPv4 over IPv6 address assignment as per RFC 6784
  • Extensive logging and statistics reporting capabilities

ISC DHCP is very modular with a range of hooks and callouts to customize its functionality. It has client and server components. The DHCP server provides network configuration, while the client queries and receives configuration from a DHCP server. ISC DHCP is maintained by Internet Systems Consortium and available as open source under the MPL 2.0 license.
