Consequently, ISC is only +able to offer support on a “best-effort” basis for some. + +Regularly Tested Platforms +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Current versions of BIND 9 are fully supported and regularly tested on the +following systems: + +- Debian 10, 11, 12 +- Ubuntu LTS 18.04, 20.04, 22.04 +- Fedora 38 +- Red Hat Enterprise Linux / CentOS / Oracle Linux 7, 8, 9 +- FreeBSD 12.4, 13.2 +- OpenBSD 7.3 +- Alpine Linux 3.18 + +The amd64, i386, armhf, and arm64 CPU architectures are all fully +supported. + +Best-Effort +~~~~~~~~~~~ + +The following are platforms on which BIND is known to build and run. ISC +makes every effort to fix bugs on these platforms, but may be unable to +do so quickly due to lack of hardware, less familiarity on the part of +engineering staff, and other constraints. None of these are tested +regularly by ISC. + +- macOS 10.12+ +- Solaris 11 +- NetBSD +- Other Linux distributions still supported by their vendors, such as: + + - Ubuntu 20.10+ + - Gentoo + - Arch Linux + +- OpenWRT/LEDE 17.01+ +- Other CPU architectures (mips, mipsel, sparc, …) + +Community-Maintained +~~~~~~~~~~~~~~~~~~~~ + +These systems may not all have the required dependencies for building +BIND easily available, although it is possible in many cases to +compile those directly from source. The community and interested parties +may wish to help with maintenance, and we welcome patch contributions, +although we cannot guarantee that we will accept them. All contributions +will be assessed against the risk of adverse effect on officially +supported platforms. + +- Platforms past or close to their respective EOL dates, such as: + + - Ubuntu 14.04, 16.04 (Ubuntu ESM releases are not supported) + - CentOS 6 + - Debian 8 Jessie, 9 Stretch + - FreeBSD 10.x, 11.x + +Unsupported Platforms +--------------------- + +These are platforms on which current versions of BIND 9 are known *not* to build or run: + +- Platforms without at least OpenSSL 1.0.2 +- Windows +- Solaris 10 and older +- Platforms that do not support IPv6 Advanced Socket API (RFC 3542) +- Platforms that do not support atomic operations (via compiler or + library) +- Linux without NPTL (Native POSIX Thread Library) +- Platforms on which **libuv** cannot be compiled + +Installing BIND 9 +----------------- + +:ref:`build_bind` contains complete instructions for how to build BIND 9. + +The ISC `Knowledgebase <https://kb.isc.org/>`_ contains many useful articles about installing +BIND 9 on specific platforms. + |
