A new Request for Comments is now available in online RFC libraries. RFC 6666 Title: A Discard Prefix for IPv6 Author: N. Hilliard, D. Freedman Status: Informational Stream: IETF Date: August 2012 Mailbox: nick@inex.ie, david.freedman@uk.clara.net Pages: 6 Characters: 10658 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-v6ops-ipv6-discard-prefix-05.txt URL: http://www.rfc-editor.org/rfc/rfc6666.txt Remote triggered black hole filtering describes a method of mitigating the effects of 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 updates the "IPv6 Special Purpose Address Registry" by explaining why a unique IPv6 prefix should be formally assigned by IANA for the purpose of facilitating IPv6 remote triggered black hole filtering and routing.
