(London Daily Mail) The internet has just received its biggest overhaul since creator Tim Berners-Lee first typed ‘www.’ into a computer.

Before Wednesday, we were running out of website addresses – not the easy-to-remember ones like www.ebay.com, but instead the numeric ones known as IP addresses.

These are the strings of numbers which give each computer or internet-connected address a long, individual number from which they can send and receive transmissions.

IPv4, as the old system was known, provided 4.3billion addreseses, which sounds a lot.

And it definitely sounded a lot when the internet was still struggling through infancy in the 1980s.

But with the rise of the world-wide-web, smartphones, tablets and the proliferation of computers across the world, the limit was reached – already at stretching point in 2008.

So now IPv6 – Internet Protocol version 6 – has come online, and brings with it 340 undecillion potential IP addresses.
