An anonymous reader writes "According to this Norwegian article in digi.no (IT Related online news), Redpill Linpro did an experiment on one of our largest online newspapers (www.vg.no) with regards to IPv6. They added a hidden iframe which pointed to a IPv6 enabled domain to test real-life problems about the reported IPv6-holes. The result was that mainly Mac OS X, older versions of Opera and a few Linux distributions exhibited problems. For Mac OS X it took 75 seconds to timeout before failing back to IPv4."
