About ISC

Our Mission

Internet Systems Consortium, Inc. (ISC) is dedicated to developing software and offering services in support of the Internet infrastructure.


Who is ISC?

ISC is the organization behind the ongoing development and distribution of the most used name server software, BIND. Our team of experts helps drive the DNS standards and author the reference implementation that is then distributed as commercial-quality Open Source software for the Internet community. ISC provides the same leadership both in standards development and software for the DHCP protocol. Over the years, the ISC team has written over 60 RFCs, and is proud to be contributors to the Internet Engineering Task Force.

ISC not only writes the software, we use it to operate critical Internet infrastructure in the form of the F-root name server. F-Root is 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 provides DNS infrastructure services to over 50 of the world’s ccTLD operators (at no charge) as part of our mission.

All of our open source software is freely available on our website. Through generous donations, sponsor support, and its commercial subsidiary, ISC is able to fulfill our mission of developing open source software products.


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. BerkeleyDigital 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.

Over the years a number of additional software systems have either found a home at ISC or were created by ISC to better support the Internet’s infrastructure. ISC funded and developed the only complete DHCP implementation. As that implementation is now very mature, ISC has started developing a replacement DHCP server, Kea.

Originally launched by a grant from UUNET Technologies, ISC’s previous funding were from Software Forum members, F-Root mirror sponsors, grants from foundations including the US National Science Foundation, support contracts, development contracts, and currently, donations.

In 2004 ISC changed its name to Internet Systems Consortium, Inc. ISC is a 501(c)(3) public benefit incorporated in the state of Delaware, with employees all around the world; having the legacy of global constituency.
