  <!--The duid is a unique identifier used in DHCPv6 to identity an       -->
  <!--interface on a device (system).  The duid is often used by servers  -->
  <!--such as dnsmasq to assign a specific IP address (and optionally a   -->
  <!--name to an interface.  The applicable standards are RFC3315 and     -->
  <!--RFC6355.  These standards actually require the duid to be fixed for -->
  <!--the hardware device and applicable to all network interfaces on     -->
  <!--that device.  It is not clear that any software currently enforces  -->
  <!--this requirement although it could be implemented manually.         -->
