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.
