IPv6, at an ISP near you?

by MarkFlax Moderator - 1/28/11 4:01 AM

I reported in my post in the link; IP address allocation running out that IPv4 address allocation is now near the end of the line.

IPv4 is the system used by the internet to allocate web site addresses. For example, has been allocated the IPv4 IP address

It is now reported that within the few weeks the world will have used up the supply of Internet addresses that computers need to communicate over the Net under the old IPv4 allocation system. Blocks of these numbers are allocated to corporate Web sites, Internet service providers, (ISPs), or other eventual owners.

IPv4 allowed for around 4.3 billion possible combinations of IP address numbers and in the early days of the internet no-one really considered that this would be insufficient. However it was realised some years ago that the allocation of IPv4 numbers had a limited life-span and that eventually, sooner rather than later, all the available IP numbers would be used. The graph of Available IPv4 blocks shows the decline in IPv4 availability.

So IPv6 was devised and developed. IPv6 allows for 3.402 x 10^38, (340 billion billion billion billion... etc), new numbers to be available. The full figure can be found displayed in all it's glory at Wolfram Alpha.

These IPv6 allocations are now available and the internet is capable of using them. But ISP's, and other content providers need to gear up for the change.

Is your ISP ready?
