+
+    <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
