Re: Well that is going to be a headache using IPv4
I want to keep this simple: IPv4 does not have a large enough address space to dish out IP addresses to 4.5 billion devices.
Well, yes but IP addresses are not distributed evenly, are there. I suspect that Canada, like the US has more than enough IPv4 addresses for the for near future. Meanwhile, Asia has run out several times over and Europe technically now has as well.
Of course, the longer providers drag their feet on the implementation of IPv6, the less well able they will be to deal with it when they have to and the less influence they will have on its future development. Hm, given the recent performance of the NSA that might not be such a bad thing! ;-)
