25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley <p>
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley ICANN is in the process of introducing a new Key Signing Key (KSK) for
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley the global root zone. BIND has multiple methods for managing DNSSEC
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley trust anchors, with somewhat different behaviors. If the root
308c7ad5f68301d19f023af616f62f3e7cbce632Andreas Gustafsson key is configured using the <span class="command"><strong>managed-keys</strong></span>
04b8111f2137a9cf9b0b71228f76b3e40ffa1173Brian Wellington statement, or if the pre-configured root key is enabled by using
04b8111f2137a9cf9b0b71228f76b3e40ffa1173Brian Wellington <span class="command"><strong>dnssec-validation auto</strong></span>, then BIND can keep
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington keys up to date automatically. Servers configured in this way
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington will roll seamlessly to the new key when it is published in
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington the root zone. However, keys configured using the
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington <span class="command"><strong>trusted-keys</strong></span> statement are not automatically
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington maintained. If your server is performing DNSSEC validation
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley and is configured using <span class="command"><strong>trusted-keys</strong></span>, you are
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington advised to change your configuration before the root zone begins
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley signing with the new KSK. This is currently scheduled for
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley October 11, 2017.

25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley With the release of BIND 9.11.0, ISC changed to the open
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley source license for BIND from the ISC license to the Mozilla
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley Public License (MPL 2.0).

25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley The MPL-2.0 license requires that if you make changes to
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley licensed software (e.g. BIND) and distribute them outside
c50fd34a4e0e6978f8ca5f6f3ad8545549c3cfeeBob Halley your organization, that you publish those changes under that
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley same license. It does not require that you publish or disclose
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley anything other than the changes you made to our software.
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley </p>

904a5734375869ffb504ed8cde6b68cafadb6d64Bob Halley This new requirement will not affect anyone who is using BIND
904a5734375869ffb504ed8cde6b68cafadb6d64Bob Halley without redistributing it, nor anyone redistributing it without
c50fd34a4e0e6978f8ca5f6f3ad8545549c3cfeeBob Halley changes, therefore this change will be without consequence
for most individuals and organizations who are using BIND.
