The draft filename implies 6man, not v6ops; which working group was asked to consider it? By "his paper", do you mean the following item in the Informative References of draft-gont-6man-teredo-loops-00? [CPNI-IPv6] Gont, F., "Security Assessment of the Internet Protocol version 6 (IPv6)", UK Centre for the Protection of National Infrastructure, (to be published). The Teredo attacks and the protocol-41 attacks appear to be mostly separate, and probably don't interact, with the possible exception of using a protocol-41 tunnel to initiate a Teredo routing loop attack. > One of your criticisms of this draft is that it doesn't cover his > USENIX material. Would you prefer that this and Mr Gont's draft be > merged? A reader of this draft might erroneously conclude that it adequately addresses all of the attacks described in the USENIX paper. However, I think it's sufficient to mention the existence of the Teredo attacks, citing the USENIX paper and the Teredo routing loop draft, because someone who reads draft-ietf-v6ops-tunnel-loops might not be aware of the related attacks without reading the actual USENIX paper. It would also be a good idea to briefly state that the Teredo attacks are mostly separate from the protocol-41 attacks, and are therefore treated in another document.
