+10 on /128 support.
If you mean RFC6164, that would be a /127 prefix.
I think Dave meant no on-link information, which unless I'm mistaken is equivalent to putting a /128 on the interface. With explicitly scoped link-local addresses, on-link information becomes a mere optimisation (although an important one in the multihomed host case, where redirects cannot cause you to switch interfaces).
" If the considered delegated prefix is an IPv6 prefix, and whenever there is at least one available prefix of length 64, a prefix of length 64 MUST be selected unless configured otherwise by an administrator. In case no prefix of length 64 would be available, a longer prefix MAY be selected."
Well spotted, thanks. Markus, would you be open to relaxing the MUST, and adding a guideline about which of the available /64s is suitable for carving up?
