Two things. First, it is nice if you don't have to allocate ports on a NAT box to make a test system available. These days you can't really count on all non-production systems having public IPv4 addresses anymore.

Obviously that only works if all systems that need access have IPv6.

However, the main killer app for IPv6 is your ISP running out of IPv4 addresses. Carrier grade NAT boxes are expensive and introduce all kinds of issues. Better to move as much traffic to IPv6 as possible.

Finally, IPv6 seems to be catching on: https://www.google.com/intl/en/ipv6/statistics.html

If at some point IPv6 traffic is the vast majority of the traffic for a website, then IPv4 traffic engineering may start to suffer. So technically the site will be reachable over IPv4 for a very long time. But it may be that at some point performance will be a lot worse then over IPv6.

It appears that Google is seeing 16% ipv6 traffic at the moment, it was 10% a year ago, and 5% the year before that; so not quite on the Ogive climb.

Mind you on a country by country basis Belgium has cleared 50% with Greece clearing 30%.

Heartening to see Zimbabwe pass 7%, an anomaly for the whole of Africa, does anyone know whats going on there? Egypt is second with 0.50%.

The map isn't set up for the Caribbean, although if you check the json used for the website Trinidad comes is at 12%. An egregious omission .

Perhaps I need to start a fantasy ipv6 migrarion website...

You're right, the Caribbean region was not covered by any of the existing links:

Should be fixed now.
