Technical Summary:

   Remote triggered black hole filtering describes a method of
   militating against denial-of-service attacks by selectively
   discarding traffic based on source or destination address.  Remote
   triggered black hole routing describes a method of selectively re-
   routing traffic into a sinkhole router (for further analysis) based
   on destination address.  This document explains why a unique IPv6
   prefix should be formally assigned by IANA for the purpose of
   facilitating IPv6 remote triggered black hole filtering and routing.

Working Group Summary

The document has received extensive review both prior to and during WG LC. As the document allocates ipv6 address 
space for a special purpose application, review was sought and obtained from IANA during the process of WG last call.

Document Quality

Field reports from operators suggested multiple solutions for an appropriate address range were already in use at the 
time of the inception of this document. A defined prefix will facilitate proper designation of the address range and 
facilitate the creation of default filters. The request has been relatively simple and uncontroversial as a proposal, and 
therefore advancement of the document towards the publication has so far encountered few obstacles.
