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
