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-server-over-tcp Mark -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org
