In terms of addresses, yes, there are more addresses in IPv6 that it
is hard to imagine.
But not in terms of subnets.
This is why number of addresses is rarely talked about in IPv6 now,
but rather the number of subnets.
There are not enough /32 subnets to give away to everyone. There
are as many /32 subnets in IPv6 as there are in IPv4. Just in IPv4,
the /32 subnet just held 1 address. We are running out of IPv4, so
by the same token, if we liberally give away /32's in IPv6, we'll
face the same exhaustion. Even faster since people are proposing to
loosen up the policies that would not have ever been thought of in
