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
