Let me repeat: You don't want to have a server sending an option that was not requested by the client. Stay with the usual ORO model. Please explain why deviating from the usual ORO model is warranted. >> - The server responds with zero (if DHCPv4-over-DHCPv6 is not >> available) or one of two options. Never both. >> - OPTION_DHCP4_O_DHCP6_ENABLE means "multicast". >> - OPTION_DHCP4_O_DHCP6_SERVER means "unicast". >> >> If this makes sense, then I would rename the options: >> s/ENABLE/MULTICAST/ and s/SERVER/UNICAST/.

I did not argue that it was necessary to tell the multicast address to the client. I did argue that it was simpler to have only one option. >> By the way, a suggestion for the document: replace all instances of >> "4o6 Server Address option" with the full option name, >> "OPTION_DHCP4_O_DHCP6_SERVER".

IMHO, the "4o6 Server Address option" is > the name of the option, while the OPTION_DHCP4_O_DHCP6_SERVER is the > option code to be assigned by the IANA. What I get from RFC3315 is that > when you refer to an option, use the name; if you want to mention the > code, then use the uppercase phrase. Sure, it is common practice, but it still makes the document harder to grep. But this is just an editorial suggestion, I don't care much. Feel free to ignore it.
