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

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.
