Abstract

   This document discusses the need for delegation of the
   E.F.F.3.IP6.ARPA DNS zone in order to enable reverse lookups for
   6bone addresses, and makes specific recommendations for the process
   needed to accomplish this.

1.  6bone and DNS

   The 6bone, whose address space was allocated by [RFC 2471], has
   provided a network for IPv6 experimentation for numerous purposes for
   seven years.  Up to the present time, reverse lookups for 6bone
   addresses have been accomplished through IP6.INT.  It is now
   important that the thousands of 6bone users be able to update their
   IPv6 software to use IP6.ARPA [RFC 3152].

   Although the 6bone has a limited life, as a phaseout plan is being
   discussed at the IETF at this time [I-D.fink-6bone-phaseout], there
   is likely to be 2.5 to 3.5 more years of operation.  During this
   remaining 6bone lifetime IP6.ARPA reverse lookup services for the
   3ffe::/16 address space are required.

   Discussions have been underway between the 6bone and RIR communities,
   about having the RIRs perform this service.  It was agreed at the San
   Francisco IETF meeting in March 2003 that it was more practical for
   the 6bone to provide this service for itself.  This would relieve the
   RIRs of the costs of providing this service, yet still provide the
   IP6.ARPA authority the ability to terminate the service when the
   planned 6bone termination date is reached (currently anticipated to
   be June 6, 2006).
