10 years ago ARIN rarely allocated less than a /19 or a /20 in IPv4. And we are still breathing today. > Yes, with suitably questionable delegations, it is possible to run out > of IPv6 quickly. Fortunately, there haven't been any questionable IPv6 delegations noticed anywhere yet. --Michael Dillon 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.
