Net powers: IPv4 is over. All hail IPv6!

The Internet's overseers bid adieu to the last 83.9 million addresses needed to connect devices to today's Net--then took advantage of the moment to evangelize the next-generation Internet and the dangers of life support for today's Net.

Today is the beginning of the end of the Internet as we know it.

The central Net authorities just handed out the last batches of IPv4 addresses at a ceremony today in Florida, beginning the cascade of scarcity that eventually will mean the computing industry must make the painful transition to the newer but incompatible IPv6.

Yesterday marked an important step toward the end of Internet plumbing as we know it.

It's hard to predict how long it will be before these eventual customers of IPv4 … Read more
