IPv4 Addresses running out

I am interested to see the effect that IPv4 exhaustion has on the state of social medias.


Here is a quote from Vint Cerf.
"Eventually there will be no more IPv4 'public address space,'" he continued. "When that exhaustion occurs (and it won't happen in a uniform way—some places will run out before others), then there will be some devices that only have IPv6 assignments. They will not be able to directly interact with IPV4-only devices."


How will this change the state of social medias? Will some devices be favored over others? What if those devices align themselves with a certain service. Imagine if all phones came packaged with a deal on Facebook, preventing you from using Twitter, blogging software, etc... but allowing unlimited access with Fbook.
