When you consider that IPv6 is a 64-bit address space, that is 64
bits are for addressing subnetworks, the "/64 spend" for
addressing hosts within a network as compared to v4 is 0%, not
And there are twice as many IPv6 bits for addressing such /64s, as
the entire IPv4 address space.
2^64 minus 2^32 is a humongous number indeed, and we know
numerically just how humongous it is.
The RIRs can collectively hand out 450 /32s a day or one /24
and one /25's worth a day, for the next 100 years, before a single
/8 would be exhausted.
And if IPv6 addressing resources last 100 years, I would say, that
the objective was more than met.
