I tried the test at http://test-ipv6.com/ cited in the article. It said "Connections to IPv6-only sites are timing out. Any web site that is IPv6 only, will appear to be down to you."

According to the test site Down For Everyone Or Just Me at http://downforeveryoneorjustme..., the IPv6 test URI http://ipv6.vm1.test-ipv6.com/... -- timed out for me -- is down for everyone. The IPv6 test URI http://2001470118119/ip/?callb... gives the result "Huh? [2001:470:1:18::119] doesn't look like a site on the interwho." (While the IPv6 address in that URI copied and pasted correctly in http://downforeveryoneorjustme..., Slashdot's editor for this comment deleted the colons in the preview.)

I have a browser extension that displays the IP address of whatever Web page I am viewing. I often see IPv6 addresses in that display. While some IPv6 addresses might not be available to me, that could be a case of a server down or the address defunct. In any case, Web sites with IPv6 addresses do not appear down for me.

While my browser does indeed render IPv6 Web pages okay, I have disabled IPv6 for my newsgroup (NNTP) reader. One NNTP server to which I subscribe too often times out unless I disable IPv6. I do not know if that is a problem with the server or with my NNTP reader application. I really do not care.

I didn't say "Why wouldn't you have a IPv6 capable network" I asked "Why would you use IPv6?"

Well, it's a good thing that I actually answered the second question, rather than the first, isn't it?

All my equipment/OS's can handle IPv6 just fine, but there's no reason to ever use it inside a local network. I can hit IPv6 outside my network just fine... http://test-ipv6.com/

Granted, that's entirely up to your ISP. But out-of-the-box equipment that's IPv6 capable equipment should support IPv6 as long as your ISP does as well.

If you only run IP4 internally, then you can only address, at best, a subset of IPv6 addresses on the public Internet.

You can test ipv6 functionality by going to test-ipv6.org.

Alas, the site is down and whois shows that the registration has expired. However, test-ipv6.com is up and running if you need it.

I like your rant, and would like to add to it P25 ('merkin, barely works) vs. TETRA (everyone else, seems to have worked for years).

CDMA predates GSM, and some providers bet big on it early in America. Nothing America can really do about it except wait for it to age and be replaced, hopefully with an international standard. Data already has been merged with LTE.

But back in context, it amuses me that my DSL provider still doesn't have the ability to give me real IPV6 connectivity, but my CDMA/LTE cell phone scores 10 out of 10 on IPV6 at http://test-ipv6.com/ on Verizon with no trickery.

(Not that I give two shits about my IPV4 vs IPV6 on my cell phone......)

A nice website has been set up for this: http://test-ipv6.com/

The World IPv6 Launch day is June 6th, 2012. Good news! Your current browser, on this computer and at this location, are expected to keep working after the Launch. [more info]

Congratulations! You appear to have both IPv4 and IPv6 Internet working. If a publisher publishes to IPv6, your browser will connect using IPv6. Your browser prefers IPv6 over IPv4 when given the choice (this is the expected outcome).

Your DNS server (possibly run by your ISP) appears to have no access to the IPv6 Internet, or is not configured to use it. This may in the future restrict your ability to reach IPv6-only sites. [more info]

"They" didn't have any bugs; I'm talking of (Google, Bing, facebook etc) what they did last year was turn on ipv6 for a day in the hope that you'd fix any problems with your equipment.

In June they'll be throwing the switch, you will only have problems if you have a broken IPv6 setup. If you have either working IPv6 or NO ipv6 you'll be fine.

You can check for yourself again on the test site.

Try it, with a tunnel.

IPv6 works pretty well with XP, there are quite a few sites already available over IPv6. A lot more are ready for IPv6 but don't enable it because about 0.1% of clients have broken IPv6 connections that look like they should work, but don't.

Of course, IPv4 won't be turned off for a VERY long time, I'd bet at least 20 years, probably longer.

If you are using Debuan/Ubuntu/etc just do this simple command:

sudo apt-get install gogoc

Tada! You got IPv6. Test it at http://test-ipv6.com/

[Disclaimer: I am a pfSense developer, so I'm a bit biased. For those of you who don't know what pfSense is, it's a BSD-based firewall distribution.]

pfSense 2.0 won't officially support IPv6, but there is a branch available that does IPv6 which will later become 2.1. I'm running it on my home router with a GIF tunnel to Hurricane Electric ( http://he.net/ http://tunnelbroker.net/) to get IPv6 even though my ISPs do not have any native IPv6 support yet. The IPv6 support is a work in progress but is complete enough that it will do what most people want/need.

Instructions for the setup and more info can be found on the pfSense IPv6 board here: http://forum.pfsense.org/index.php/board,52.0.html

I get a 10/10 on the IPv6 tests from http://test-ipv6.com/ on all my PCs as well as my Droid X running 2.3.3. If you're already using pfSense 2.0, give the IPv6 code a try, setup a tunnel to he.net, and enjoy. Doesn't take too long at all to setup.

Either your ISP is supporting IPv6, or your OS is using a tunnel. Windows Vista and 7 by default do by try 6to4 and teredo tunnels if the ISP doesn't assign an ipv6.

Linux users can just install miredo to have a teredo tunnel. It is nice to use ipv6 capable DNS, such as OpenNIC; do these and you'll get 10/10 score at http://test-ipv6.com/

More ISPs should be supporting dual stacks by now, that means an ipv6 capable DNS and assign both ipv6 and ipv4 to clients. That will ensure a transparent switchover and ease ipv6 only services, which will start slowly, but will growth with time; especially with regions like Asia running out of ipv4 addys.

It makes sense even if the ISP itself is using a tunnel for all its customers, while their upstream providers get a clue. Of course that also can be done in any LAN, which is why doing it in your home to get the starting knowledge is a good idea...

I posted a comment much like this in the last IPv6 thread, but here it goes again. :-)

and ya blah blah... @ISP's please take care of this..

Its not my headache as long as I can get an IP to access the internet with..

I'm on Comcast. I don't think I'll have too many problems. I ran a simple online test with results reproduced below. I didn't have to lift a finger to do this. Any modern OS that's up to date on patches should not have too many problems. Still though, the article makes a good point. Organization that really depend on things working properly, and that don't want a nasty surprise? They should do a dry run of IPv6-only conditions, and fix any problems. I noticed that Comcast isn't giving me IPv6 DNS yet. Hopefully they'll fix that before June, otherwise all the tests passed.

Real routers don't have 'state tables'.

Ask your ISP for IPv6 access. Enable your web server/site for IPv6 day. Use a 'web bug' tracker item to identify broken thins.

visit places like http://test-ipv6.com/ to try to understand how ready you are.

Make sure if you have a tunnel, or use one, you do not add too much latency to your connection. The CDNs won't send your traffic over IPv6 if your IPv6 goes to some other continent or geographical region.

Hmm, the full test requires some browser holes (intentional). It doesn't work under Chromium 9 (dev version), even if I have JavaScript enabled (by default).

OTOH I get 2/3 white-on-green check marks on the simple version of the test for methods "IPv4" and "IPv4 or IPv6". I get a broken (no) image for the third method, pure "IPv6".

I seem to have failed an online IPv6 test. Should I be worried?

First, Google would have to index IPv6 websites. They do not. Google presently only indexes IPv4 websites. Of course Google would need to maintain two tables of indexes: the current index which doesn't include IPv6 and a new index which did include IPv6-only websites. The IPv6-only website index would need to be presented only to IPv6-enabled clients who are searching.

To test that Google doesn't index IPv6 webites (unless they have IPv4, which doesn't count), search for my made-up word "gorberakinNAY" and you will find it on an IPv4-only page. Search for "gorberakin" plus the word "YAY" (I don't want to say it as I don't want Google to index this page). The results are on an IPv6-only page (linked to by the first page and others) and you will not find it when you search for it on non-IPv6--searching search engines.

Further, I have yet another keyword like this which can only be accessed if you have IPv6 connectivity and your DNS servers have IPv6 connectivity.

If you can pass with a 10/10 score at this IPv6 Test then you can get to all 3 of my websites.

Is there a way of pointing my browser somewhere to find out if everything 'at my end' and my ISP connection is fully functional?

You can try http://test-ipv6.com/ or http://ds.test-ipv6.com/

That isn't what they're doing (yet). Although the headline/summary made it sound like they were shutting out IPv4 users, this is not the case. They will be supporting both simultaneously.

You are correct. I believe it's called "running a dual stack."

If slashdotters want to test whether their present system (client, router, NAT, firewall, proxy, ISP) is IPv6-ready, go here. Its free and there s a ton of good information about the conversion "issues" and what you'll need to do to become a full IPv6 citizen.
