DOWNLOADS Open Source Means Freedom, But Also Responsibility ISC develops and distributes four open source Internet networking software packages: BIND 9, ISC DHCP, Kea DHCP, and Stork, and operates the F-Root domain server. We would love you to use our open source in your network, but first, please consider whether open source is an appropriate solution for you. Open source is for DIYers - you need to be prepared to set up a provisioning and monitoring system that will meet your specific needs. We offer some tools, including dig, and our Stork graphical management system, and our software has remote management interfaces, but you will need to make your own decisions about management tools. We publish both source tarballs and application packages for popular operating systems, but you must be prepared to select, configure and maintain your server operating system. Help is available, on our free community support mailing list, and via professional support contracts with ISC, but nobody here is going to configure or manage your systems for you. Open source is for people who want the freedom to collaborate and contribute as a member of a community. It is for people who want complete control over their network design, security, and data. It is not for everyone. BIND 9 The original, complete open source DNS implementation. Learn more ISC DHCP Open source DHCP server, relay agent, and client software, now EOL.
