" I have no hesitation in recommending John and I will use him again on future projects for Livewire and my other ventures "
Jonathan - Livewire |
Possibly not the most technically accurate document I've ever written, but I'm hoping it makes something very complex a little more understandable.
IPv4 AddressesAn Internet Protocol Address is a bit like a telephone number for devices on the internet. In much the same way as phone numbers, every device needs it's own number. Unfortunately, though, the current version 4 IP address system can only support just over 4 billion devices. The current estimate suggests there are around 200 billion internet devices already - which has required some 'technical magic' (NAT) - but this can't go on indefinitely. IPv6 AddressesWe'll not talk about IPv5, as Apple were involved :-) The good news is that IPv6 is here and working, with the right setup. IPv4 is 32bit, while IPv6 is 128it - that will support up to 340 trillion trillion trillion devices! All of the current mobile devices and PCs support IPv4 and IPv6, but many ISPs and routers are still years behind. |
