As a measure of its magnitude, consider this: In 2012, the new Internet address system, IPv6, created more than 340 trillion trillion trillion (3.4 x 1038) addresses – that is, around 4.8 x 1028 addresses for every person on earth. That should be sufficient to service the five billion devices that currently connect to the internet, and the 22 billion devices forecast to be in use by 2020.
阿布扎比——我们已经建立了一个浩瀚程度超乎我们理解的网络世界。可以这样来形容它的大小：2012年，新的互联网地址系统IPv6创建了超过340兆兆兆（3.4×1038）个地址——折合地球上每个人的地址约为4.8×1028个。新系统不但可以为目前联网的五十亿台设备提供服务，此外也能满足到2020年预计220亿台设备的联网需要。
