"Expecting everyone to have IPv6 connectivity sorted out throughout the enterprise network before June 8th is ludicrous..."

It's 2011. What's ludicrous is enterprise desktops with broken dual-stack support.

If IPv6 day weren't happening, remaining problems would not get fixed. Then in a year or two, major companies would start dual-stacking their public webservers in an unsynchronized fashion, and end users would be complaining about miscellaneous brokenness off and on for months, possibly years.

Tip: Point your customers to http://omgipv6day.com/ , now.

The site will tell if your Internet access will be fine on World IPv6 day. A positive answer means that you either have IPv4 only connection (no broken IPv6 DNS responses or routes), or have a fully operational IPv6 nameserver and route to the Internet. A negative answer means that your computer was tricked into using IPv6 while no actual IPv6 connectivity exists (and thus you are going to have problems on June 8th).

For a more detailed test: http://test-ipv6.com/

I've run that on all manner of devices and infrastructures and it has never told me I will have any problems on World IPv6 Day. That's not because it is inacurate, it's because the vast majority of setups will continue to work perfectly on June 8th.

The more out-of-the-box your setup is, the more likely it'll work (modulo a few broken OS/browser combos listed in the ARIN wiki).

You might experience problems in environments where someone has been playing with IPv6 and left it half-broken (or, in my case, tried to be too smart and used DNS server on Cisco router ;)

I get different results from those sites. The first says that everything will be fine because my setup only does IPv4[1]. The second says everything will be fine because my setup fully implements IPv6[2].

This seems somehow strange.

1 - This web browser (at this location) looks safe. You'll just keep using IPv4.

2 - Congratulations! You appear to have both IPv4 and IPv6 internet working.

Or just attempt to load a dual-stack site. A few examples off the top of my head: http://www.freebsd.org/ http://www.debian.org/ http://www.ucla.edu/

Each of those has been dual-stack for years now. If you can load them without an egregious delay then you'll have no problem on June 8th.

I also suggest test-ipv6.com which gives interesting results and feedback

For exemple, today while looking to replace my DSL modem local DNS server for different reasons (http://en.blog.guylhem.net if you want to know) I realized usual DNS servers such as 8.8.8.8 or 4.2.2.4 couldn't work for aaaa.v6ns.test-ipv6.com.

Yes I know, using 4.2.2.4 makes baby jesus cry, but it was easy to remember and faster than 8.8.8.8. Yet now I've got a new favorite - ordns.he.net

Try it for yourself : dig aaaa.v6ns.test-ipv6.com at your favorite server and see if it works.

I assume you just mean that test-ipv6 gives you the warning:

  "Your DNS server (possibly run by your ISP) appears to have no access to the IPv6 internet, or is not configured to use it."

I get that too (I have IPv4/IPv6 connectivity)

I really wouldn't worry about it too much. We're FAR from the day when anybody could contemplate publishing their public DNS zones using just IPv6-only nameservers. Therefore a recursive IPv4-only server will continue to work for a LONG time.

The more immediate problem is publishing servers running IPv4-only (making a fully-recursive IPv6 only server impossible) The good news is that the large DNS-providers seem to be mostly on the ball about this. There are, however, still a few TLDs with IPv4-only DNS (.co is one example)

IPv6 has existed for over 15 years. It's time to have one day of bugs and pain to move deployment forward.

I'm personally looking forward to this: I've had IPv6 connectivity for quite a while. I can resolve names over IPv6. Google works fine.

If I can do it, anyone can do it.

Is there any way to get residential IPv6 access easily?

In the UK, Andrews and Arnold (aaisp) offer IPv6 by default for their DSL customers. There aren't m/any consumer routers that support it, but a Vigor 120 ADSL PPPoA to PPPoE bridge can be used in front of a single PC or Linux router.

I also recommand the FritzBox 7390, VDSL/ADSL2+ modem with SIP over DECT and fully IPv6 capable with "out of the box" support for 6to4 or sixxs tunnel. Great purchase, runs linux, very hacker friendly

comcast has ipv6 trials going on now, but only in one or two areas: http://www.comcast6.net/

you can get a free tunnel from a number of providers like http://www.tunnelbroker.net/ or http://www.sixxs.net/

In Australia, Internode has made IPv6 available to its customers.
