We have IPv6 on all our staff edge vlans, which covers several thousand machines. The figures would have probably been much higher if we had managed to get IPv6 on our student halls of residence. It was planned for IPv6 day that students would have IPv6 but unfortunately we ran into an IPv6 related bug on the routers which route the student traffic. Additionally alot of our traffic is now wireless traffic, and again this isn't IPv6 enabled. Due to the fact we use vlan override, on our wireless network, and the wireless solution we use has very broken IPv6 which doesn't work with vlan override. The 5.46% was quite good considering but what was even better was not a single service desk case related to IPv6. In case anyone is interested these are the figures we captured via netflow on the campus border (not within the campus): DNS Server stats: IPv4 DNS Inbound: 2.7 GB (88.86%) IPv6 DNS Inbound: 346.65 MB (11.14%) IPv4 DNS Outbound: 1.41GB (92.85%) IPv6 DNS Inbound: 111.22 (7.15%) RADIUS Server stats (eduroam): IPv4 RADIUS: 5.17MB (15.73%) IPv6 RADIUS: 27.69MB (84.27%) IPv6 Traffic: Total Bytes Inbound: 35.47G Total Bytes Outbound: 6.74G Average bps Inbound: 3.53M Average bps Outbound: 670.29k Peak bps Inbound: 31.86M Peak bps Outbound: 12.1M 95th percentile bps inbound: 9.44M 95th percentile bps outbound: 1.15M IPv6 Services inbound: http - 26.31GB (74.17% of total IPv6 traffic ) macromedia - 7.19GB (20.26%) udp - 791.35MB (2.18%) https - 582.98MB (1.6%) dns - 346.55MB (0.95%) ssh - 261.19MB (0.72%) IPv6 Services Outbound: ssh - 4.61GB (68.36%) http - 1.12GB (16.64%) udp - 402.24MB (5.83%) https - 260.89MB (3.78%) macromedia - 228.29MB (3.31%) dns - 111.35MB (1.61%) Compared to IPv4: Inbound IPv6 accounted for 0.4% of total traffic Outbound IPv6 accounted for 0.15% of total traffic --- Scott Armitage, Senior IT Services Specialist (Networks and Security), IT Services, Loughborough University
