2012 Isn´t the End of the World

The IPv4 system doesn´t disappear in 2012 nor does the Internet suddenly stop working. Rather, it can´t easily expand without the implementation of IPv6 in the networks and edge devices comprising the Internet.One can imagine the use of proxy devices that could act as application-layer gateways to help such devices reach IPv6-only servers, but there are various drawbacks to this kind of design (including some difficulty with end-to-end cryptography for confidentiality).
