-# The bind.keys file is used to override the built-in DNSSEC trust anchors
-# which are included as part of BIND 9.  The only trust anchors it contains
-# are for the DNS root zone (".").  Trust anchors for any other zones MUST
-# be configured elsewhere; if they are configured here, they will not be
-# recognized or used by named.
-#
-# To use the built-in root key, set "dnssec-validation auto;" in the
-# named.conf options, or else leave "dnssec-validation" unset.  If
-# "dnssec-validation" is set to "yes", then the keys in this file are
-# ignored; keys will need to be explicitly configured in named.conf for
-# validation to work.  "auto" is the default setting, unless named is
-# built with "configure --disable-auto-validation", in which case the
-# default is "yes".
-#
-# This file is NOT expected to be user-configured.
-#
-# Servers being set up for the first time can use the contents of this file
-# as initializing keys; thereafter, the keys in the managed key database
-# will be trusted and maintained automatically.
-#
-# These keys are current as of Mar 2019.  If any key fails to initialize
-# correctly, it may have expired.  In that event you should replace this
-# file with a current version.  The latest version of bind.keys can always
-# be obtained from ISC at https://www.isc.org/bind-keys.
-#
-# See https://data.iana.org/root-anchors/root-anchors.xml for current trust
-# anchor information for the root zone.
