The Internet Sky Is Falling

In 1999, while at Network World, Carolyn Marsan and I interviewed Vint Cerf about IPv6. Cerf was beseeching the entire industry to move as quickly a possible to IPv6 since IPv4 addresses were running out.

Thanks to a kludge or two, 11 years later there are still IPv4 addresses left -- but not many. Over 90 percent of all possible IPv4 addresses are in use. At this rate, all of them will be gone by 2013, says the Number Resource Organization.

The good news is that IPv6 has been here for a long time, it works, and companies such as Microsoft are doing a great job supporting it.

I guess the lesson here is we should all get moving on IPv6. Vint Cert will thank you!
