We have IPv6 throughout our Computer Science dept here at Southampton, both on client network and public facing services (DNS, MX, web, ...). On June 8th we saw over 100GB of IPv6 traffic against 550GB or so of IPv4 traffic, so IPv6 was over 15%. We do have IPv6 on our WLAN but that's because we haven't yet migrated to the Cisco WLC solution; we're waiting for IPv6 support through VLAN override in that first, as Scott explained. Unfortunately that week was the week after exams finish, so our network had very light load with students not coming in and academics marking. Tim
