-      <title>Interface Detection and Socket Handling</title>
-      <para>Both the DHCPv4 and DHCPv6 components share network
-      interface detection routines. Interface detection is
-      currently supported on Linux, all BSD family (FreeBSD, NetBSD,
-      OpenBSD), Mac OS X, and Solaris 11 systems.</para>
-
-      <para>DHCPv4 requires special raw-socket processing to send and receive
-      packets from hosts that do not have an IPv4 address assigned. Support
-      for this operation is implemented on Linux, FreeBSD, NetBSD, and OpenBSD.
-      It is likely that the DHCPv4 component will not work in certain cases on
-      other systems.</para>
