ISC develops and distributes three open source Internet networking software packages: BIND 9, ISC DHCP, and Kea DHCP. BIND 9, ISC’s Domain Name System (DNS) software program, is widely used on the Internet by enterprises and service providers, offering a robust and stable platform on top of which organizations can build distributed computing systems. ISC DHCP implements the Dynamic Host Configuration Protocol for connection to an IP network, offering a complete solution for implementing DHCP servers, relay agents, and clients. ISC DHCP is a mature program with many features, but it can be cumbersome for operators to maintain. Kea DHCP is ISC newer DHCP software, and is designed for modular extension, dynamic reconfiguration, and high performance.
In addition to our open source software, ISC also operates critical Internet infrastructure in the form of the F-Root server, one of the 13 Internet root name servers that power the global Internet. Through F-Root, ISC pioneered the use of global “anycast” in DNS.
Our staff’s contributions are instrumental to various Internet governance and community initiatives, and ISC engineers have written or co-authored more than 85 of the technical standards (RFCs) that are essential to interoperability on the Internet.
Our open source software is freely available here on our website. ISC’s work is supported by the sale of software support contracts to organizations and enterprises that want to see free open source maintained and extended for everyone.
