10 years ago ARIN rarely allocated less than a /19 or a /20 in IPv4. And we
are still breathing today.

Fortunately, there haven't been any questionable IPv6 delegations
noticed anywhere yet.

P.S. A block of /19 in IPv4 is the same percentage of the total IPV4
address space as a block of /19 in IPv6 is of the total IPv6 address space.
