That is the wording the community wanted at the time. We didn't want to
limit the policy to just 6RD, and at the time, the providers who wanted 6RD
already had allocations.

Nevertheless, I don't believe ARIN would approve a /16 or a /20 for a
justification as trivial as 6RD, so it is still a red herring.

To qualify for a /16 or /20, you must show your need using section
6.5.2.1—Size, and 6RD wouldn't qualify, at least not in my opinion.

Thanks.
