In your previous mail you wrote:
It frustrated me a great deal that IPv6-in-IPv4 tunneling with the same
protocol number 41 could be used for various things:
1. configured tunneling
2. automatic tunneling
2.1 automatic tunneling with compatible addresses
2.2 6to4
2.3 ISATAP
(more to come?)
=> oh, you forgot 6over4 !
But really, IMO the tougher issue is how HAO will/should be handled.
=> we can start for the today situation: HAO are not recognized/supported?
