Our goal is to transform Compaq, and to do it over the next 180 days - Mike Capellas, Q
DADDY OF the Interweb, Vint Cerf is warning that businesses are not doing enough to upgrade to IPv6.
He told the Times that the world is about to run out of the IP addresses unless companies pull finger and upgrade to the new system.
Cerf said that unless preparations were made now, some computers might not be able to go online and the connectivity of the internet might be damaged.
ISPs in particular needed to prepare and that time was running out for a smooth transition.
He estimates that IPv4 addresses will run out in 2010 and possibly as early as next year.
While the two protocol systems will run in tandem, IPv4 addresses will still work as normal, if IPv6 is not widely adopted, then those using it may find themselves unable to connect across the whole internet, he warned. µ

is running out of IP addresses
There are plenty of unused addresses in the internet and another bunch of addresses under the control of a few corporations which they basically dont need.

These are the net blocks:

001 to 023 thats 385 million addresses alone.
025 to 040, 251 million addresses
042...
046...
049 to 057...
100 to 115.....
173 to 187....
197...
223 to 255, these are originally intended for multicast something that has never happened or been of any real usage, therefore the addresse could be used.

So if you sum the numbers above you will find surprisingly find that almost 40% of the internet addresses are just not used or are in hands of corporations that cannot give them any useful usage. The total amount of free addresses is 1.7bn.
Ed: Are you volunteer to tell these companies they need to return that addresses ? Or to rewrite all software which assumes 223 to 255 is multicast and will not try to connect to them ? It's not so simple and even 1.7b addresses will not solve problem for long (look at China, India ...). 

We really need to go to IPv6.
If internet became,say local, that is No long distance or public lost intrest, so active IP address base was much lower or if Surgeon General Declared InterNet Hibernate Day Internationale'.Yeah,m IP4 could be last standard, leaving IP6 addresses reassignment yet that would also mean Uninventing new router & directory technology or corrupting it & Santa would Have To Commit Suicide.

The bringer of the apocalypse has to ride a horse, because his other ride ran out of petrol.
I'd like to see just one of Mr. Cerf's dire predictions actually COME TRUE.
Come on, let's have an actual meltdown for once, okay ?
Please ?
