Internet Systems Consortium (ISC)

ISC software, of which BIND and ISC DHCP are the two best‐known examples, is open source. ISC’s passion is Internet core technology. ISC’s widely‐imitated Managed Open Source process ensures software quality while keeping it completely open and available. ISC operates high‐reliability global networks of DNS root servers (F‐root) and authoritative DNS servers both for non‐profit and commercial enterprises.

ISC is actively involved in Internet protocol and standards development, particularly in the areas of DNSSEC and IPv6. ISC is supported by donations from generous sponsors, by program membership fees, and by increasing revenues from for-profit subsidiaries.
