Hi,
Another way of looking at it would be what would the world population =
need to be in order to exhaust all of the space v6 based on /48s /56s or =
/64s per head / household - and is this population number ever going to =
happen in what time conceivable time frame.
Another interesting calculation would be to divide the land mass area by =
that population figure - let alone the habital area.
2 to 48 =3D 281,474,976,710,658 or 280K Billion separate /48s =
assignments.
(Current world population 6.7 Billion forecast 14 Billion in 2100)
World Landmass (Total All Areas): 148.94 million sq km
So Each Person at the point of IPv6 exhaustion will have 0.53 sq meters =
to stand on while using all their IPv6 devices.
I think it is safe to say that the world will be facing other more =
significant problems long long long before we get anywhere near having =
to worry about running out of IPv6 space because we are assigning each =
individual a /48.
There are surely technical benefits from a routing perspective if all =
the end user assignments are the same size - therefore should the =
technical considerations here not override any argument about =
conservation of space seeing as the above hopefully proves the fallacy =
of needing to conserve IPv6 address space????

Which just reinforces the argument that we ought to give people /48s
rather than /56es, /60s, or /64s even though those with a failure of
imagination may not be able to figure out a reason anyone would need
that much space.
