   Title:   Preference for IPv6 ULAs over IPv4 addresses in RFC6724

Abstract:

   This document updates [RFC6724] based on operational experience
   gained since its publication over ten years ago.  In particular it
   updates the precedence of Unique Local Addresses (ULAs) in the
   default address selection policy table, which as originally defined
   by [RFC6724] has lower precedence than legacy IPv4 addressing.  The
   update places both IPv6 Global Unicast Addresses (GUAs) and ULAs
   ahead of all IPv4 addresses on the policy table to better suit
   operational deployment and management of ULAs in production.  In
   updating the [RFC6724] default policy table, this document also
   demotes the preference for 6to4 addresses.  These changes to default
   behavior improve supportability of common use cases such as, but not
   limited to, automatic / unmanaged scenarios.  It is recognized that
   some less common deployment scenarios may require explicit
   configuration or custom changes to achieve desired operational
   parameters.
