IPv6 Routing in Slovenia

  1. 1. Nathalie Trenaman| 23 May 2017 | SINOG 4.0 As seen from the world IPv6 Routing in Slovenia Given by my colleague from R&D, Christian Teuschel
  2. 2. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 2 Regional Measurements • RIPE NCC measures many different things: - IPv6 RIPEness - Atlas - RIS - Member Demographics - RIPE Database - etc…
  3. 3. 3 IPv6 Ripeness • Rating system: - One star if the LIR has an IPv6 allocation - Additional stars if: - IPv6 Prefix is announced on router - A route6 object is in the RIPE Database - Reverse DNS is set up - A list of 4 star LIRs: - http://ripeness.ripe.net
  4. 4. 4 IPv6 RIPEness: 15932 LIRs 4 stars 21% 3 stars 15% 2 stars 10% 1 star 29% No IPv6 25%
  5. 5. 5 IPv6 RIPEness Slovenia: 60 LIRs 4 stars 33% 3 stars 27% 2 stars 17% 1 star 18% No IPv6 5%
  6. 6. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 6 4 Stars over Time
  7. 7. 7 IPv6 RIPEness: the 5th star • You already earned 4 stars… • Actual IPv6 deployment is the 5th star! • Two ways to get it: - Provide content over IPv6 - Provide IPv6 access to users • New t-shirt!!!
  8. 8. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 8 5th Star in Slovenia
  9. 9. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 9 IPv6 Prefixes: RIPE DB vs BGP /29 /30 /31 /32 /46 /47 /48 0 10 20 30 40 50 10 20 30 40 /29 /30 /31 /32 /46 /47 /48 BGP RIPE DB
  10. 10. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 10 IPv6 Prefixes Seen in BGP
  11. 11. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 11 Atlas Probes in Slovenia
  12. 12. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 12 Lets have some fun • There are 28 active, IPv6 capable probes in SI • Make a traceroute to sinog.si - has working IPv6
  13. 13. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 13 Interesting fact (1) • Slovenia is invading Austria?
  14. 14. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 14 Staying Local
  15. 15. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 15 It’s Jan’s home.. Staying Local
  16. 16. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 16 Is that….
  17. 17. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 17 ….6to4? 2002::/16
  18. 18. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 18 A Comparison To IPv4 • Same measurement but with IPv4 IPv4 IPv6 # of probes 44 28 Average hops 7,6 6,9 Average RTT 5,3 9,9
  19. 19. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 19 RTT in IPv6 • There are 4 probes with relatively high RTT • 2 in the same ASN • In the first 3, the problem is in the first hop • The last one….well…6to4 ;)
  20. 20. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 20 Interesting fact (2) • 2 probes do something funky…
  21. 21. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 21 RIPE Atlas IXP Country Jedi • Are paths between ASes staying in country? • Any difference between IPv4 and IPv6? • How many paths go via local IXP? • Could adding peers improve reachability? • Experimental tool - Feature requests welcome! - Depends on probe distribution in country
  22. 22. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 22 Methodology • Trace route mesh between RIPE Atlas probes • Identifying ASNs in country using RIPEstat - Using a maximum of two probes per AS • Identifying IXP and IXP LANs in PeeringDB
  23. 23. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 23 Output for SI (v4) http://sg-pub.ripe.net/emile/ixp-country-jedi/latest/SI/ixpcountry/index.html
  24. 24. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 24 IXP Country Jedi (v4) http://sg-pub.ripe.net/emile/ixp-country-jedi/latest/SI/geopath/index.html
  25. 25. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 25 IXP Country Jedi (v6)
  26. 26. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 26 A Comparison • There are 11 probes that have both IPv4 and IPv6 and have the same origin AS for IPv4 and IPv6 • IPv4: 172 unique AS paths - 153 via SIX-SI (89%) • IPv6: 80 unique AS paths - 63 via SIX-SI (79%) - 2 unique paths via Hurricane Electric (2,5%) - 3 unique paths via DE-CIX (3,75%)
  27. 27. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 27 Out-of-Country Traffic • The paths to HE and DE-CIX come from AS199071 (Prunk) • All other local traffic stays local, both for IPv4 and IPv6
  28. 28. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 28 Conclusions • 95% of our Slovenian members have IPv6 allocations • Most local IPv6 traffic stays local • A few Atlas Probes have broken IPv6 on the router • A 6to4 tunnel causes slower RTT • Next step: IPv6 content and users! - And if your LIR has 5 stars, get the T-shirt
  29. 29. Nathalie Trenaman | SINOG 4.0 | 23 May 2017 29 IPv6 Adoption Seen By Google
