A few days ago, it was rumored that IPv6 (see Wikipedia), the upcoming network protocol was currently not supported in Windows Phone 7.0 (evidently started because our browser cannot connect to a IPv6 website).
Fast forward today and now there's information through Microsoft that suggests that this is "fixed" in WP7 Mango. If you head to MSDN, you'll see listed under 'Fields' what appears to be full-support for IPv6 on board in OS v7.1 aka Mango.
What that all means of course is there's nothing to see here, don't worry, our new OS does not have an Achilles heel when it comes to web-browsing--assuming nothing major happens in the next 6 months.
