IPv6 is growing rapidly. Chart from http://bgp.potaroo.net/v6/as2.0/index.html
Over the past few years, the growth of IPv6 has increased greatly. Already, there is about 100,000 times more space advertised on IPv6 as on IPv4. Well, that’s not exactly correct, since we “count” addresses differently.
As of today, there are around 202,926,147,961,349 so-called “/64′s” being advertised on IPv6, vs 2,469,125,216 IPv4 addresses. The “/64′s” are the typical “end user” address space being advertised – each of which contains 18,446,744,073,709,551,616 IP addresses!

Part 1 of 2 parts
IPv6 will change how we use the internet, again. To the typical user, there is no difference; web sites work the same. But email is a different story.
When using IPv6, addresses are allocated in a different manner. Most end-users today get one IP address, which is shared between multiple machines using a Network Address Translation (NAT) router. In IPv6, each user gets an address block – a /64 – of address space. This is great news, because end-to-end application on the Internet will work much better, and there will be no NAT in the way.
A /64 is a huge amount of space –...
