[4] FEA0::/10 was previously defined as a Site-Local scoped address prefix. This definition has been deprecated as of September 2004 [RFC3879]. I think that's a typo for FEC0::/10 As soon as the ULA draft is approved, FC00::/7 can also be marked as Reserved by IETF. IANA's

Eric asks a good question. I think the chances that some implementers will choose to store IPv4 addresses in IPv6-sized structures is 100%. So I am strongly of the view that that the IPv4-compatible *format*, i.e. a ::/96 prefix, needs to be reserved and never allocated. Of course, it should never

Firstly, when we were developing RFC 3697, we were told very forcefully by the WG to remove use cases from the draft and simply to define generic boundary semantics. I think exactly the same should apply to this draft, so all the references to 6LSA should be removed. Then we'll be able to see more
