And why do you think that is?

If we give a /32 to anyone who asks for it, I *guarantee* you that
major ISPs will stop accepting /32's.  There will be too many of

They'll take it down to /30s or /24s or something like that.

The number of addresses in IPv6 is incredibly large, but not the
number of /32 subnets.

Guys, do the math.  There are the same number of /32 subnets in IPv6
as in IPv4.  We are running out of IPv4.

We'll run out of IPv6 if there is no barrier to entry on a /32.

2^32 = 4,294,967,296
