Several people have suggested I (re)post information about test-ipv6.com here.
http://test-ipv6.com .. tests ipv4 and ipv6 by dns name tests dual stack (will the client break on World IPv6 Day?) tests ipv6 by IP literal (teredo can pass this) gives advice to end user about current status and (depending on circumstances) more information "broken" users (can't connect to dual stack) are solicited for info Caution: does depend on javascript.
http://test-ipv6.com/simple_test.html Eyeball test only for user, with instructions; no javascript required.
Please direct any comments, flames, etc directly to me instead of the list. I've added enough noise already :-)
Note you can have totally broken IPv6 connectivity and still be fine on World IPv6 day. You just need applications with good multi-homing support. No web site can check this for you. If you are a application developer and want TCP example code that will work well with a broken IPv6 connection have a look at my blog. http://www.isc.org/community/blog/201101/how-to-connect-to-a-multi-homed-ser...
