Consequently, ISC is only 38able to offer support on a “best-effort” basis for some. 39 40Regularly Tested Platforms 41~~~~~~~~~~~~~~~~~~~~~~~~~~ 42 43Current versions of BIND 9 are fully supported and regularly tested on the 44following systems: 45 46- Debian 12 47- Ubuntu LTS 20.04, 22.04, 24.04 48- Fedora 40 49- Red Hat Enterprise Linux / CentOS / Oracle Linux 8, 9 50- FreeBSD 13.3, 14.1 51- Alpine Linux 3.20 52 53The amd64 CPU architecture is fully supported and regularly tested. 54 55Best-Effort 56~~~~~~~~~~~ 57 58The following are platforms on which BIND is known to build and run. ISC 59makes every effort to fix bugs on these platforms, but may be unable to 60do so quickly due to lack of hardware, less familiarity on the part of 61engineering staff, and other constraints. None of these are tested 62regularly by ISC. 63 64- macOS 10.12+ 65- Solaris 11 66- NetBSD 67- OpenBSD 68- Other Linux distributions still supported by their vendors, such as: 69 70 - Ubuntu 22.10+ 71 - Gentoo 72 - Arch Linux 73 74- OpenWRT/LEDE 17.01+ 75- Other CPU architectures (arm, arm64, mips64, ppc64, s390x) 76 77Community-Maintained 78~~~~~~~~~~~~~~~~~~~~ 79 80These systems may not all have the required dependencies for building 81BIND easily available, although it is possible in many cases to 82compile those directly from source. The community and interested parties 83may wish to help with maintenance, and we welcome patch contributions, 84although we cannot guarantee that we will accept them. All contributions 85will be assessed against the risk of adverse effect on officially 86supported platforms. 87 88- Platforms past or close to their respective EOL dates, such as: 89 90 - Ubuntu 14.04, 16.04, 18.04 (Ubuntu ESM releases are not supported) 91 - Red Hat Enterprise Linux / CentOS / Oracle Linux 6, 7 92 - Debian 8 Jessie, 9 Stretch, 10 Buster, 11 Bullseye 93 - FreeBSD 10.x, 11.x 94 95- Less common CPU architectures (i386, i686, mips, mipsel, sparc, ppc, and others) 96 97Unsupported Platforms 98--------------------- 99 100These are platforms on which current versions of BIND 9 are known *not* to build or run: 101 102- Platforms without at least OpenSSL 1.0.2 103- Windows 104- Solaris 10 and older 105- Platforms that do not support IPv6 Advanced Socket API (:rfc:`3542`) 106- Platforms that do not support atomic operations (via compiler or 107 library) 108- Linux without NPTL (Native POSIX Thread Library) 109- Platforms on which **libuv >= 1.34** cannot be compiled or is not available 110 111Installing BIND 9 112----------------- 113 114:ref:`build_bind` contains complete instructions for how to build BIND 9. 115 116The ISC `Knowledgebase <https://kb.isc.org/>`_ contains many useful articles about installing 117BIND 9 on specific platforms. 118 119
