One comment on the draft is that I think it needs to be clear that load balancing is ONLY used for DHCPv6 client messages that do not include a server-identifier option (this is Solicit, Information-Request (if no server-identifier option), Rebind, and Confirm). Load balancing MUST NOT be used if a server-identifier option exists in the client's message, as then only that server should respond.

Moving this to a WG draft seems reasonable.

It appears that it is hard for several different reasons (the grad student who did all the work is gone, Brian is now fully retired and about to go on a month's vacation, etc...) for Brian Carpenter to just run the same test on Pearson but he can probably do some lesser amount of testing. I'm continuing to converse with him on this...

Thanks,
Donald
