The Internet Systems Consortium (ISC) is a non-profit organization that plays a crucial role in the development and maintenance of the Internet's underlying infrastructure.
ISC was founded in 1992 by a group of volunteers who were passionate about making the Internet a more open and accessible resource for everyone.
One of the key services provided by ISC is the management of critical Internet resources, including the root zone of the Domain Name System (DNS).
This involves coordinating the global DNS infrastructure, which is used by billions of people around the world to access websites and online services.

History of ISC
The Internet Systems Consortium, or ISC, has a rich history that spans several decades. The company was originally founded as the Internet Software Consortium, Inc. in 1994 by Paul Vixie, Rick Adams, and Carl Malamud.
One of the key reasons for ISC's founding was to manage and fund the development of BIND software, which was a crucial component of the internet infrastructure at the time. ISC was designated as a root name server operator by IANA, originally as NS.ISC.ORG and later as F.ROOT-SERVERS.NET.
In 2004, ISC underwent a reorganization and changed its name to Internet Systems Consortium, Inc. This change marked a new chapter in the company's history.

Early Years

The Internet Systems Consortium, Inc. was originally founded as the Internet Software Consortium, Inc. by Paul Vixie, Rick Adams, and Carl Malamud.
These founders believed that BIND's maintenance and development needed to be managed and funded by an independent organization.
The company was designated as a root name server operator by IANA, originally as NS.ISC.ORG and later as F.ROOT-SERVERS.NET.
In January 2004, the company underwent a name change to Internet Systems Consortium, Inc.
ISC spun off its Security Business Unit to Farsight Security, Inc. in July 2013, a new company started by ISC founder Paul Vixie.
In early 2020, ISC closed its headquarters in Redwood City, California and relocated its operations to Newmarket, New Hampshire.

Milestones
The history of ISC is a story of significant milestones that have shaped the organization into what it is today. The first milestone was the establishment of the International Society for Cryptology (ISC) in 1981.
The ISC's first conference was held in 1983, which marked a major turning point for the organization. This event brought together experts from around the world to share knowledge and ideas on cryptography.

The ISC's publication, Cryptologia, was first released in 1976, providing a platform for researchers to share their findings and insights on cryptography. This publication has been a valuable resource for the cryptography community ever since.
The ISC's efforts led to the development of various cryptographic protocols, including the Data Encryption Standard (DES) in 1977.
Open Source Philosophy
At Internet Systems Consortium (ISC), open source is more than just a philosophy - it's a way of life. ISC develops and maintains open source networking software.
The ISC DHCP software is a prime example of this open source approach, implementing the Dynamic Host Configuration Protocol for connection to an IP network. It offers a complete solution for implementing DHCP servers, relay agents, and clients.
ISC's open source software includes BIND and two DHCP implementations: ISC DHCP and Kea DHCP. This allows developers to contribute to and customize the software to suit their needs.
The ISC DHCP solution supports both IPv4 and IPv6, making it suitable for use in high-volume and high-reliability applications.

ISC's DNS Services
ISC operates the DNS "F" root server, the first such server to be distributed using anycast. This server was a significant milestone in the history of DNS, marking a new era in how root servers are managed.
In 2007, ISC and ICANN signed an agreement regarding the operation of F, the first such agreement made between ICANN and a root-server operator. This partnership has ensured the continued stability and security of the DNS root server.
BIND 9 is open source software that implements the Domain Name System (DNS) protocols for the Internet. It's a reference implementation of those protocols, but also production-grade software suitable for high-volume and high-reliability applications.

DNS Root Server
ISC operates the DNS "F" root server, the first such server to be distributed using anycast. This was a significant achievement in the world of DNS.
In 2007, ISC and ICANN signed an agreement regarding the operation of F, the first such agreement made between ICANN and a root-server operator.
Bind DNS Server Software
Bind DNS Server Software is open source software that implements the Domain Name System (DNS) protocols for the Internet.
It is a reference implementation of those protocols, but it is also production-grade software, suitable for use in high-volume and high-reliability applications.
Bind 9 is widely used on the Internet, providing a robust and stable platform on top of which organizations can build distributed computing systems with the knowledge that those systems are fully compliant with published DNS standards.
The DNS protocols are part of the core Internet standards, specifying the process by which one computer can find another computer on the basis of its name.
Bind 9 is an implementation of the Domain Name System (DNS) protocols and is available for free download at www.isc.org/downloads/.
