The switch of mobile devices from 2G/3G technology using IPv4 to LTE (aka 4G) using IPv6 will fix a large amount of this, "As IPv4 increasingly became the de facto standard for networked digital communication, the cost of embedding substantial computing power into handheld devices dropped. Mobile phones have become viable Internet hosts. New specifications of 4G devices require IPv6 addressing." http://en.wikipedia.org/wiki/IPv4_address_exhaustion#Mobile_devices http://en.wikipedia.org/wiki/IPv4_address_exhaustion#Mobile_... IPv4 runs as a subset of IPv6 for those of you not into the IP stuff too deep. IPv6 devices can talk to IPv4 through border devices similar to NAT today so we can use "private" RFC1918 addresses.
