You're aware that RIPE has already made some /19 and /20 IPv6 allocations?
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.
