I considered this question back in 2011 when the question of /16 or /20
came up in the discussion of ARIN-2011-3. I concluded it was possible to
justify a /16. Let me put the question slightly differently: Is it possible
to justify more than a /20? There were already /19s allocated by other
RIRs, so I concluded that it is possible to justify more than a /20. I also
believe nibble alignment is important, so I support /16 as the maximum
allocation. Nevertheless, such /16 allocation should be rare; one in a
decade aligns with that belief.

However, those who think it is impossible to justify a /16 for an initial
allocation should support this policy.

Thanks.
