It's not too surprising to see SPAWAR [0] up so high; the US Department of Defense has required IPv6 compatibility for devices being added to their networks for a while now (I think around 2003)[1]. If you scroll a bit further down the list, Defense Research and Engineering Network (DREN) is at 8.32% as well.
