How will IPv6 impact everyday users? (World IPv6 Day)
As I understand when we have finally made the switch to IPv6 not only will NAT be unnecessary but it is incompatible with IPv6?
Will that mean that ISPs will have to serve multiple IP addresses per customer? Will they provide a range of addresses for each customer or as each device connects will they get an IP address that isn't necessarily near that of the other devices in their house?
But overall will this be bad for the Internet users? as surely it will allow ISPs to see exactly how many devices are being used, and so allow them to charge for the use of additional IP addresses? And then if that happens, what happens when you try to connect an extra device to your network? Will it simply not get an IP address?
In my home we have about 15-20 devices connected at once, but for places where there are hundreds of devices, it seems like the perfect opportunity for ISPs to charge more?
I think I may have it completely wrong, so is there somewhere where there is an explanation of who things will work when IPv6 becomes the norm?
Will this and that happen? – Sorry, I don't think anybody knows for sure how exactly the IPv4 → IPv6 progression will happen, but the real question is: Why do you want to know? Is there an actual problem to solve? Can't we just wait and see until this becomes more of a practical issue? – slhck – 2012-03-31T21:49:37.283
3This is not about the progression, but when it's finished progressing, which should be well documented. Since when is waiting for a problem to occur rather trying to get ahead of it, a better option? – Jonathan. – 2012-03-31T22:00:18.720
Of course, but then you'll need to define "bad" too. Will ISPs charge for something? Who knows? What specifically are you trying to avoid or get ahead of? – slhck – 2012-03-31T22:04:15.173
1Bad is a word in the dictionary, what is there to define? Will IPv6 actually mean the removal of NAT? How will IP addresses be assigned? – Jonathan. – 2012-03-31T22:16:56.267
2The answer provided here doesnt overlap with the answers in the question that is given as the reason to close. But at least someone answered the question before you trigger happy people got to it. Once again on Superuser, closing the question has done absolutely nothing... – Jonathan. – 2012-04-01T13:10:30.050
Look, I didn't choose the duplicate. I just don't think it's constructive to ask for what ISPs will do and what they'll charge. Feel free to post a reopen request on [meta]. – slhck – 2012-04-01T20:49:16.467
