It's based on IPv4 and ARIN being unlikely to gain territory or a
significant additional percentage of IPv4 allocations. Admittedly,
v6 could change things, but, frankly, it looks like v6 will most likely
make the database smaller not larger unless significant policy changes
However, another thing to consider is that when things do change, so
can policies. I'm betting we can change ARIN policies if it becomes
necessary much faster than IPv6 will cause the policy change to be
