World IPv6 Day - What did we learn?

  1. 1. World IPv6 Day -What did we learn?emile.aben@ripe.net(Channeled by Vesna Manojlovic)Netnod Autumn Meeting 2011
  2. 2. RIPE NCC Measurements - World IPv6 Day• IPv6 Eyechart and 6to4 (not in this talk)• Active measurements – Sources: 49 vantage points (RIPE TTM, CAIDA Ark, ...) – Destinations: 53 participant or already dual-stacked sites – From 2011-06-01 to 2011-06-11 we measured – DNS: A and/or AAAA records – ping(6)/traceroute(6) – HTTP over IPv4 and IPv6 2
  3. 3. Measurement vantage points 3
  4. 4. Percentage of vantage points seeing AAAA v6day 4
  5. 5. Percentage of vantage points seeing AAAA v6day Negative caching 4
  6. 6. Percentage of vantage points seeing AAAA v6day TTL caching Negative caching 4
  7. 7. Test and monitor
  8. 8. You don’t want this to happen On IPv4:On IPv6: 6
  9. 9. Or this ... Comparing DNS,ping and HTTP IPv6 measurements to www.commerce.gov from 2011-06-09 0:00 UTC to 2011-06-10 12:00 UTC 100 % % AAAA queries returning an IPv6 address % HTTP responses == 200 80 % % ICMPv6 ping success 60 % 40 % 20 % 0% 00 04 08 12 16 20 00 04 08 12 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 0 0 0 0 0 0 0 0 0 0 7

Comparing DNS,ping and HTTP IPv6 measurements to www.commerce.gov from 2011-06-09 0:00 UTC to 2011-06-10 12:00 UTC 100 % % AAAA queries returning an IPv6 address % HTTP responses == 200 80 % % ICMPv6 ping success 60 % 40 % 20 % 0% 00 04 08 12 16 20 00 04 08 12 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 0 0 0 0 0 0 0 0 0 0 v6 on www turned off but v6 service still at end of v6day announced 7
  12. 12. Test and monitor - lessons learned 8
  13. 13. Test and monitor - lessons learned• Test when deploying something – The more real-life, the less likely you !@#$-ed up• Monitor your infrastructure• People2people reachability – Avoidable situations like Level3 and Dept. Commerce – Contact info up to date in RIR databases (whois) – Monitor the web (NANOG, *NOG, Twitter, ...) 8
  14. 14. Global view
  15. 15. Performance of src/dst pairs on 2011-06-08 Distribution of IPv4/IPv6 relative performance • Bell-shaped – centered around 0 IPv4 performs better IPv6 performs better – with fatter IPv4-side – (62% / 38%) • Dual-stack = twoFrequency chances for best performance! – Real-time apps could exploit this (voice, gaming) + 400 % + 350 % + 300 % + 250 % + 200 % + 150 % + 100 % + 50 % + 40 % + 30 % + 20 % + 10 % +0% + 10 % + 20 % + 30 % + 40 % + 50 % + 100 % + 150 % + 200 % + 250 % + 300 % + 350 % + 400 % best performing protocol, as percentage−wise increase over the least performing protocol 10

  21. 21. Conclusions - what we learned• IPv6/dual-stack works just fine, but make sure that – It is properly tested and monitored (like IPv4) – Your network can reach all others (like IPv4)• Dual-stack = Two chances for best performance• Days like this ‘work’ – Raise awareness – Give people a target to work towards – We’re ready for a next IPv6(day|week|month|year|∞) 13
