For anyone who doesn’t know the name Vint Cerf, he’s one of the brains behind the IP system and one of the world’s most well-known and respected computer scientists. He’s stated that the internet doesn’t have enough unique codes that allow computers to communicate with each other.
Once the IP addresses run out, the connectivity of the internet will be damaged and some computers won’t be able to go online.
“This is like the internet running out of telephone numbers and with no new numbers, you can’t have more subscribers,” Mr. Cerf said. He went on to state that the switch to a new system.
IPv6 (Internet Protocol version six) has been ready for a decade and is already used in Japan to connect thousands of earthquake sensors through a computer system that sends automatic alerts to television programmes and turns traffic lights red.
IPv6 addresses are 128 bits long and so provide a possible 340 trillion, trillion, trillion address space compared to the 40-something billion that the current IPv4 is capable of holding.
