Given that there's enough addresses to assign around 1000000 addresses to every bacterial cell on the planet, you can safely expect that it will last longer than ipv4. It's not a matter of "oh, lets double it that should be big enough", the ipv6 space is around 18 orders of magnitude larger. Computers and our uses for them would have to change enormously for us to exhaust that. Not saying it won't ever happen, but it'll be a while. https://en.m.wikipedia.org/wiki/Orders_of_magnitude_(numbers) https://en.m.wikipedia.org/wiki/Orders_of_magnitude_(numbers... (not to be a smartass about what orders of magnitude means, just because the article has some really cool examples)
