BIND is open source software licenced under the terms of the Mozilla

The license requires that if you make changes to BIND and distribute
|
|
them outside your organization, those changes must be published under
|
|
the same license. It does not require that you publish or disclose
|
|
anything other than the changes you have made to our software. This
|
|
requirement does not affect anyone who is using BIND, with or without
|
|
modifications, without redistributing it, nor anyone redistributing
|
|
BIND without changes.

The end-of-life date for BIND 9.12 has not yet been determined.
|
|
However, it is not intended to be an Extended Support Version (ESV)
|
|
branch; accordingly, support will end after the next stable
|
|
branch (9.14) becomes available. Those needing a longer-lived
|
|
branch are encouraged to use the current ESV, BIND 9.11, which
|
|
will be supported until December 2021. See
|
