Definitive Guide to IPv6 adoption

Tue Oct 19 11:47:58 UTC 2010

Hi,

Maybe we should reserve the first couple of bits to serve as a planet identifier, so that once we have colonized the heavens Star Trek Federation style we can route to all of those Billions of life forms.

Routing convergence times shouldn’t be too much of an issue even with light version 1 (while we wait for FTL transport mechanisms) as I suspect there wont be too many interplanetary transit providers to have worry about in the routing mesh.

But again in all seriousness - surely this is a problem for the distant future (sadly and Stephen Hawking would agree about our species' need for colonization to ensure survival) and in the meantime we just get on as quickly as possible with getting IPv6 rolled out and adhering to standards of how we do it so we don't create yet another inconsistent mess with everyone following different "standard" best practices.

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 = 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.
