Technical Summary

   At the time a host establishes a new link-layer connection, it may or
   may not have a valid IP configuration for Internet connectivity.  The
   host may check for link change, i.e.  determine whether a link change
   has occurred, and then, based on the result, it can automatically
   decide whether its IP configuration is still valid or not.  During
   link identity detection, the host may also collect necessary
   information to initiate a new IP configuration for the case that the
   IP subnet has changed.  In this memo, this procedure is called
   Detecting Network Attachment (DNA).  DNA schemes should be precise,
   sufficiently fast, secure and of limited signaling.
