Internet will run out of IP addresses by 2010, warns Vint Cerf

The “father of the internet” has warned that the web is running out of addresses and users need to act now to change to a new system.

Vint Cerf, the man who helped invent the system and one of the world’s leading computer scientists, said that the web does not have enough unique codes that allow computers to communicate with each other.

Preparations had to be made now, he said, to switch addresses to a new system.
