ARIN IPv4 Addresses Run Out Tomorrow
jcomeau_ictx provided that teaser of a headline, but writes: Not really. But the countdown at tunnelbroker.net should go to zero sometime tomorrow around noon, considering it's at 45,107 as I write this, it's counting down about one address every two seconds, and there are 86,400 seconds per day. Just happened to notice it today. Might be worth a little celebration at every NOC and IT enterprise tomorrow.
There aren't four billion public IP addresses in use. The problem is that in the early days they handed out class A subnets like they were candy, wasting millions of IP addresses with every one. Most computers don't have their own public IP address -- they have a private IP address and access the Internet via NAT.
What a fool believes, he sees, no wise man has the power to reason away.
