i called up dlink support today and talked with a lady on the phone about the future of the dir-855 getting a firmeware upgrade for ipv6 and she stated it will not be getting one and i would need to purchase the dir-825 to get ipv6 support.
this is a really huge let down that a lesser model would get the upgrade and the better model will not. i have been a loyal buyer of dlink routers for several years, but i am seeking for another brand that has better support. i would be more than willing to buy a new router if i was using a older one, but im using there top-end model.
