33c9436ef1a43d3c0fc3d9be9b4b0509daa83223Tinderbox User ICANN is in the process of introducing a new Key Signing Key (KSK) for
33c9436ef1a43d3c0fc3d9be9b4b0509daa83223Tinderbox User the global root zone. BIND has multiple methods for managing DNSSEC
33c9436ef1a43d3c0fc3d9be9b4b0509daa83223Tinderbox User trust anchors, with somewhat different behaviors. If the root
33c9436ef1a43d3c0fc3d9be9b4b0509daa83223Tinderbox User key is configured using the <span class="command"><strong>managed-keys</strong></span>
33c9436ef1a43d3c0fc3d9be9b4b0509daa83223Tinderbox User statement, or if the pre-configured root key is enabled by using
363b21045b718d06d414784c96193dc9a233e8c5Tinderbox User <span class="command"><strong>dnssec-validation auto</strong></span>, then BIND can keep keys up
363b21045b718d06d414784c96193dc9a233e8c5Tinderbox User to date automatically. Servers configured in this way should have
363b21045b718d06d414784c96193dc9a233e8c5Tinderbox User begun the process of rolling to the new key when it was published in
363b21045b718d06d414784c96193dc9a233e8c5Tinderbox User the root zone in July 2017. However, keys configured using the
33c9436ef1a43d3c0fc3d9be9b4b0509daa83223Tinderbox User <span class="command"><strong>trusted-keys</strong></span> statement are not automatically
363b21045b718d06d414784c96193dc9a233e8c5Tinderbox User maintained. If your server is performing DNSSEC validation and is
363b21045b718d06d414784c96193dc9a233e8c5Tinderbox User configured using <span class="command"><strong>trusted-keys</strong></span>, you are advised to
363b21045b718d06d414784c96193dc9a233e8c5Tinderbox User change your configuration before the root zone begins signing with
363b21045b718d06d414784c96193dc9a233e8c5Tinderbox User the new KSK. This is currently scheduled for October 11, 2017.
