+# CLAT implements the client part of 464XLAT (RFC 6877), an
+# architecture that provides IPv4 connectivity to hosts on IPv6-only
+# networks.
+#
+# The default value for the connection property 'ipv4.clat' is still
+# 'no'. Change it globally to 'auto' (1) so that CLAT gets enabled
+# automatically when the network advertises a PREF64 and there is no
+# native IPv4 configured (either because DHCPv4 option 108 was
+# received or because there is no DHCPv4 server).
+#
+# See: https://fedoraproject.org/wiki/Changes/IPv6-Mostly_Support_In_NetworkManager
+
+# Do not modify this file. You can hide/overwrite this file by
+# creating "/etc/NetworkManager/conf.d/24-clat-auto.conf". You can
+# also add configuration snippets with higher priority that override
+# this setting (see `man 5 NetworkManager.conf`). Most importantly,
+# this snippet only sets default values for the profile. You can
+# explicitly set the value for each profile, so that this default
+# value is not used.
+
+# For example, on a particular profile/network set
+#
+#   $ nmcli connection modify "$PROFILE" ipv4.clat no
+#
+# to disable CLAT. This prevents the default from this file to take
+# effect.
