Internet Systems Consortium, Inc. (ISC) is dedicated to developing software and offering services in support of the Internet infrastructure.
Founded in 1994, 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’s intended replacement for ISC DHCP, and is designed for dynamic reconfiguration.
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. ISC also offers DNS hosting services for selected non-profits.
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.
All of our open source software is freely available here on our website. ISC’s work is supported by the sale of software support contracts, and by donations from users who want to see free open source maintained and extended for everyone.
ISC is a 501(c)(3) public benefit incorporated in the state of Delaware, with about 38 employees in eight countries.
ISC was originally founded in 1994 as Internet Software Consortium, Inc., to continue the work of maintaining and enhancing BIND following in the footsteps of CSRG at U.C. Berkeley, Digital Equipment Corporation, and Vixie Enterprises. BIND was then (and is now) an essential component of the Internet’s infrastructure.
ISC’s founders – Paul Vixie, Carl Malamud, and Rick Adams – felt that BIND’s continued support and enhancement should be managed and funded by an independent entity and made it so. IANA designated ISC as a root name server operator (first NS.ISC.ORG, then F.ROOT-SERVERS.NET) allowing ISC to interact equally with root name server operators and better support the global use of BIND.
In 2004, ISC changed its name to Internet Systems Consortium, Inc.
ISC is dedicated to developing software and offering services in support of the Internet infrastructure. We believe that open source in general, and ISC’s software in particular, protects the Internet from being overtaken by businesses or governments who may not have the world’s interests at heart. It is essential for individuals and organizations to have options for their critical Internet functions that don’t require them to purchase from vendors that are looking to profit from their weakness.
