Release Notes for BIND Version 9.11.6-P1

Introduction

This document summarizes changes since the last production release on the
BIND 9.11 (Extended Support Version) branch. Please see the CHANGES file
for a further list of bug fixes and other changes.

Download

The latest versions of BIND 9 software can always be found at http://
www.isc.org/downloads/. There you will find additional information about
each release, source code, and pre-compiled versions for Microsoft Windows
operating systems.

License Change

With the release of BIND 9.11.0, ISC changed to the open source license
for BIND from the ISC license to the Mozilla Public License (MPL 2.0).

The MPL-2.0 license requires that if you make changes to licensed software
(e.g. BIND) and distribute them outside your organization, that you
publish those changes under that same license. It does not require that
you publish or disclose anything other than the changes you made to our
software.

This requirement will not affect anyone who is using BIND, with or without
modifications, without redistributing it, nor anyone redistributing it
without changes. Therefore, this change will be without consequence for
most individuals and organizations who are using BIND.

Those unsure whether or not the license change affects their use of BIND,
or who wish to discuss how to comply with the license may contact ISC at
https://www.isc.org/mission/contact/.

Legacy Windows No Longer Supported

As of BIND 9.11.2, Windows XP and Windows 2003 are no longer supported
platforms for BIND; "XP" binaries are no longer available for download
from ISC.

Security Fixes
