                      Table 1: Current Assignments

How should we make this into the actual IANA registry?

Well, first some higher authority would have to approve the erratum.
Then I'm pretty sure the AD could simply ask IANA to make the update.

Another interesting question is who will instruct implementers
of RFC7217 to add a check for this case.

I can help socialize this in at *BSD and Linux. Maybe even provide a patch.

Thanks Fernando. I have raised a potential issue with this range in the 6man discussion thread on this topic. I would like the discussion there to wrap up, and I can push the buttons based on what the WG concludes.

Suresh
