+ <title>[DUID] Section Options</title>
+
+ <para>This section configures the DHCP Unique Idendifier (DUID) value used by DHCP
+ protocol. DHCPv6 client protocol sends the DHCP Unique Identifier and the interface
+ Identity Association Identifier (IAID) to a DHCP server when acquiring a dynamic IPv6
+ address. DHCPv4 client protocol sends IAID and DUID to the DHCP server when acquiring
+ a dynamic IPv4 address if <option>ClientIdentifier=duid</option>. IAID and DUID allows a
+ DHCP server to uniquely identify the machine and the interface requesting a DHCP IP.</para>
+
+ <para>The DUID value specified here overrides the DUID that systemd-networkd generates
+ using the machine-id from the <filename>/etc/machine-id</filename> file, as well as the
+ global DUID that may be specified in <citerefentry><refentrytitle>networkd.conf
+ </refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
