Vint Cerf, one of the web’s founding fathers, is leading a global campaign to encourage web service providers and IT managers to switch from the current system, IPv4, to IPv6. The new standard offers many trillions of new web addresses, but cannot be accessed from modems and routers that only use IPv4. It is likely, however, that most of the changes needed will take place without consumers losing access to any part of the web because they will be part of the standard software and hardware upgrade cycle.
