Googlebot is visiting my website via IPv6

Interesting: Googlebot is visiting my website via IPv6:

2001:4860:4801:1303:0:6006:1300:b075 - - [22/Nov/2010:16:46:21 +0100] "GET /newsserver.txt HTTP/1.1" 200 1966 "" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)"

2001:4860:4801:1402:0:6006:1300:b075 - - [23/Nov/2010:04:49:22 +0100] "GET /robots.txt HTTP/1.1" 200 26 "" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)"

Note the two different IPv6 source addresses:

2001:4860:4801:1303:0:6006:1300:b075

2001:4860:4801:1402:0:6006:1300:b075

I wonder how Google handles the information found on IPv6-only websites. Will Google reveal IPv6-only websites via ipv6.google.com?

IPv6 test sites

Here's an overview of sites that can test your IPv6 connectivity and give a bit more information than "you're connecting over ...":

• http://www.appelboor.com/ipv6.html hard core IPv6-test site, no frills, links to a nice iGoogle Gadget "IPv6 Checker"
  
• http://test-ipv6.com/ beautiful IPv6-test site which does see Teredo IPv6 connectivity on Windows Vista and Windows 7, but strangely enough awards 0 points for that
• http://ipv6-test.com/ beautiful IPv6-test site, including a speed test, but does not see any Teredo IPv6 connectivity on Windows Vista and Windows 7
• iGoogle Gadget "IPv6 Checker" is here : runs embedded in your iGoogle (www.google.com/ig). Shows details about your IPv6, including Teredo and name resolving
  

HTH

iGoogle Gadget to check your IPv6 address and connectivity

If you use iGoogle and you want to know your IPv6 connectivity, here is a gadget to report your IPv6 address and IPv6 network connectivity.

See the screendump for an example output.

It works for all operatings systems (Windows, Linux, Mac OS X, iPhone, iPad, Android, etc) and all browsers able to view iGoogle.


Or just click the button below to add this gadget to your iGoogle:

Cool: iPhone OS 4 does IPv6 (on an IPv6 enabled Wifi network)

Cool: Apparently iPhone OS 4 does IPv6 too, as I found this entry in my webserver log file: 

2620:0:da0:4003:6233:bbbb:fedb:aaaa - - [20/Aug/2010:18:00:01 +0200] "GET /set-ipv6resolving.js HTTP/1.1" 200 21 "http://www.appelboor.com/ipv6.html" "Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_0_2 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8A400 Safari/6531.22.7"

(IPv6 address changed a bit for privacy reasons).

The IPv6 address is from Louisiana State University, so it's not IPv6 over UMTS/GSM or something like that; it's probably an iPhone on a University Wifi network doing IPv6, visiting http://www.appelboor.com/ipv6.html to check his/her IPv6 connectivity.

Android 2.1 actually does IPv6!

Wow, that's cool: Android 2.1 (on a HTC Desire) really, really does IPv6. Proof: visiting http://wattcher.015.info/check-ipv6-refresh.html results in this logging:

2001:838:b1a:0:223:76ff:fefc:979a - - [30/May/2010:12:21:34 +0200] "GET /cgi-bin/fill-address-with-REMOTE_ADDR.cgi HTTP/1.1" 200 25000 "http://wattcher.015.info/check-ipv6-refresh.html" "Mozilla/5.0 (Linux; U; Android 2.1-update1; en-nl; Desire_A8181 Build/ERE27) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17"

Details: the Android was connected to a Wifi-LAN offering IPv6 via Router Advertisement

IPv6 only Vuze

Just for Fun:

It's quite easy (and interesting) to create an IPv6-only Vuze (aka Azureus). This is how:

In Vuze, choose Tools -> Options, and then on the left side choose "IP Filters", and then on the right side check "Enable" and "ALLOW these ranges". Don't fill out any IP address in the white block below. Then click Apply.

The result of this setting is that all IPv4 peers and seeds are blocked, and thus only IPv6 peers and seeds are allowed.

Included are the screendumps of my results downloading an Ubuntu ISO image. I was connected to about 50 IPv6 peers and seeds. Quite nice.

With these results I can see the relative amount of Miredo/Teredo 2001:0:-addresses, 6to4 2002:address, and the other (non-automatic) IPv6 addresses.

Remarks:

• Needless to say, you much first check that your system does IPv6. So check that you can visit http://ipv6.google.com/ and http://wattcher.015.info/check-ipv6-refresh.html
  
• If you can't find "ALLOW these ranges" in the options, just type it in in the left lower search box in Tools -> Options

Overview of Teredo Relay Servers

Overview of Teredo Relay Servers is here: http://bgpmon.net/teredo.php

Only 13 in the world ... I'm surprised Teredo/Miredo works so well for me.

IPv6 at 150 kmph

Cool: IPv6 at 150 kmph ... in the train to Brussels. Thanks to KPN Mobile and my Nokia N97 combined with Teredo/Miredo on my Ubuntu. Result:

Let's check your IPv6 connectivity:

OK, you have IPv6 network connectivity. Your IPv6 address is 2001:0:53aa:64c:b6:14c1:4331:57e.

Congratulations: you have IPv6 name resolving, too. This means you have full IPv6 connectivity.

Vigor 2130 supports IPv6 via DHCPv6 and TSPC

Cool: the Vigor 2130 broadband router from Draytek supports IPv6. The WAN-IPv6-connection can be established via Static IPv6, DHCPv6 and TSPC. See included screendump.

Uncool: the price: 119 Euro.

NbIServ.de offers cheap vServers with IPv6

The German vServer / hosting provider NbIServ.de now offers IPv6. As their vServers start at 2.60 Euro per month, this is a great way to get an IPv6 enabled root server based on Debian, Ubuntu, Fedora, Suse or some other Linux.

One downside: most texts, including the output of the operating system (!), is in German.

IPv6 announcement here, the cheapest vServer with all options here.

SABnzbd + XSnews + IPv6 = Walhalla

Free binary newsserver via Xsnews and IPv6

This is quite incredible: Xsnews offers free access to their binary newsservers over IPv6. I've measured downloads at linespeed (18 Mbps)! It's Xsnews' way to promote IPv6. It works much better than Eweka's and Xs4all's newszilla free IPv6 newsservice.


It's quite easy to get access: fill out your email address on http://www.xsnews.com/ipv6/ipv6_aanvraag.php , and then wait a few minutes for the mail to arrive with all information.
The information will look like

Hostname: reader.ipv6.xsnews.nl
Username: ipv6-12345
Password: aaa12345bb

Fill out that information in SABnzbd (www.sabnzbd.org) and start downloading! This works on Linux and Mac OS X with IPv6 enabled. If you haven't got IPv6 yet, use miredo.
It works automagically on Windows Vista and Windows 7 thanks to the built-in Teredo IPv6. On Windows XP you have to activate Teredo IPv6 yourself.

If you don't use SABnzbd but an other news downloader, you might need the IPv6 address of reader.ipv6.xsnews.nl, which is: 2a02:d28:5580:c::101:5

Happy downloading!

Cool: IPv6 directly connected to "1-wire" sensors

Cool! Someone has used IPv6 to give each "1-wire" sensor it's own IPv6 address and webserver. He has created an IPv6 stack in a microcontroller. Impressive.

See here: http://www.shapeshifter.se/2009/07/10/1-wire-meets-ipv6/

If you don't want to read the full article, here are the URLs for the sensors:

2001:16d8:ffe5:002:28c1:b4f6:100:035

2001:16d8:ffe5:002:2813:caf6:100:050


PS: you will get some XML code that will show things like temperature.

Transmission 1.80 released with "Improved IPv6 support" ... still no IPv6 webinterface

Bittorrent client Transmission version 1.80 has been released. The release notes (http://trac.transmissionbt.com/wiki/Changes#version-1.80) say "Improved IPv6 support" ... what would that mean? My hope is of course that the webinterface of Transmission is now IPv6-enabled.

Ubuntu Lucid Lynx (alpha 2) has Transmission 1.80, so I've run Lucid to see if the webinterface is indeed IPv6 enabled ...

But alas: the webinterface is not listening on the IPv6 interface. See tests below; first IPv4 (OK), then IPv6 (no connection).

More waiting before we can access Transmission's webinterface over IPv6. :-(

main Google search page www.google.com on IPv6 too [UPDATE: Selected ISPs only]

UPDATE: Google is indeed on IPv6, but only via ISPs participating in "Google over IPv6". The post below was on a KPN Hotspot, which is connected to Xs4all, which is such a participator.
Pity. Normal users with non-IPv6 ISPs have to wait. :-(


Wow, even the mainstream Google page is on IPv6, too! So not only ipv6.google.com, but also www.google.com and www.google.nl

Bravo Vista! (Sort of)

I'm typing this on a friend's Windows Vista machine. The strange thing: the machine is directly connected to Internet and thus has a public IPv4 address. The interesting thing: IPv6 works ... not based on the Teredo 2001:0: address, but based on the 6to4 2002: address. The IPv6-only website http://ipv6.ip6.me/ shows my 2002: address.

So: Bravo Vista for the IPv6 connectivity.

Oh, wait: the IPv4 & IPv6 website http://www.ipv6.surfnet.nl/ shows my IPv4 address. Vista thus still likes IPv4 more than IPv6 ... :-(
