Right. But in this thread some say we should no longer do DHCP-typical-info in the RA, and at the same time they propose to do it, provided the backend info comes from a DHCP server. Hence my question about whether a delegated prefix (another DHCP-typical-info) would be ok for this concept. (I author an earlier draft in this space). >> If yes, would it be ok to include a Prefix Delegation option as >> well in the RA?

The benefit of RA is that "everyone can see > them and the information contained applies to *all* consumers, and is > periodically refreshed without having to poll". PD is, by > definition, very specific to the device where you delegate to... I tend to agree that RA's content is generally valid for everyone receiving that RA, and that typically RAs are multicasted to all nodes on a link. However, there are some specific cases where the RA is unicast to particular nodes and contain information specific to that node. For example in Proxy Mobile IPv6 RFC5213 an access router sends an RA to a particular mobile host attaching to it, and it puts inside a prefix to make believe that particular node to be at its home. Each node has a different home prefix. Another example is in Fast Mobile IPv6 protocol RFC4068 where a Proxy RA contains an address specific to a mobile. A more remote example is that of RPL RFC6550 which uses a new ICMP message 'RPL Control Message' remotely similar to RA, and whose destination is unicast. Apart from that, the use case I am considering is fast exchanges of IP messages to establish quickly short-lived communications (10ms IP establishment address/defroute, and app-layer communications during a few minutes). Used in vehicular communications. A vehicle containing a cellular link (SIM subscription) may offer Internet connectivity to a SIM-less vehicle nearby - mobile billboard vehicle, like in this figure http://en.wikipedia.org/wiki/File:MSNBC_mobile_billboard_at_Union_Station.jpg (check the "Free WiFi" banner).
