Hello, I wanted to follow up on Fred's comment earlier in this thread: >> OK. That will greatly simplify the checks needed for new automatic tunneling protocols that have a format other than ip-proto-41. For the designers of new tunneling protocols, shall perhaps a recommendation on best practices be included into the draft or another document, that for the new tunnels a different protocol value / format should be used? Examples of such protocol / formats could include using a different next-protocol value, potentially with some multiplexing schema if just using different next-protocol values is not scalable, or possibly some other format.

All the attacks rely on the fact that the ISATAP router encapsulates/decapsulates a packet > the 6to4 relay decapsulates/encapsulates, respectively.
