Technical Summary

   This document describes an extension that causes nodes to generate
   global scope addresses with randomized interface identifiers that
   change over time.  Changing global scope addresses over time limits
   the window of time during which eavesdroppers and other information
   collectors may trivially perform address-based network activity
   correlation when the same address is employed for multiple
   transactions by the same node.  Additionally, it reduces the window
   of exposure of a node via an addresses that becomes revealed as a
   result of active communication.  This document obsoletes RFC4941.

Working Group Summary

   This document is an update of RFC4941. The document
   shepherd has reviewed every change to the document as it
   has processed as well as a thorough read through of the
   whole final document.

   Ole Trøan is the document shepherd.
   Erik Kline is the responsible AD.
