2 IPv6 adoption metrics User end hosts Server-side measurements e.g., Google reports 20% of the hosts have IPv6 2
3 IPv6 adoption metrics User end hosts Server-side measurements Networks Allocations Routing (IANA) (BGP)... e.g., Google reports 20% of the hosts have IPv6 e.g., 23% of the Autonomous Systems announce IPv6 3
4 IPv6 adoption metrics User end hosts Server-side measurements Networks Allocations Routing (IANA) (BGP) Services / Content Client-side measurements... e.g., Google reports 20% of the hosts have IPv6 e.g., 23% of the Autonomous Systems announce IPv6 e.g., 13% of the Alexa top 1M Web sites have set IPv6 4
5 IPv6 adoption metrics User end hosts Server-side measurements Networks Allocations Routing (IANA) (BGP) Services / Content Client-side measurements... e.g., Google reports 20% of the hosts support IPv6 Many different connectivity metrics. What about traffic? e.g., 23% of the Autonomous Systems announce IPv6 13% of the Alexa top 1M Web sites have set IPv6 5
6 IPv6 traffic statistics Vantage point % of IPv6 traffic Year 260 networks <1% 2013 Dual-stack ISP 11 % 2016 AMS-IX (IXP) 1-3 %
7 IPv6 traffic statistics Vantage point % of IPv6 traffic Year 260 networks <1% 2013 Dual-stack ISP 11 % 2016 AMS-IX (IXP) 1-3 % 2017 What is the interplay between connectivity and traffic? A dual-stack ISP is ideal to study barriers for IPv6 traffic 7
8 Dual-stack ISP: when is IPv6 connectivity used? Home network (i) OS (ii) applications Devices need to support IPv6 e.g., old OSes, some IoT don t 8
9 Dual-stack ISP: when is IPv6 connectivity used? Home network (i) OS (ii) applications (iii) CPE IPv6 needs to be enabled at many CPEs 9
10 Dual-stack ISP: when is IPv6 connectivity used? Home network Dual-stack ISP IPv4 traffic IPv6 traffic (i) OS (ii) applications (iii) CPE (iv) ISP connectivity ISP has to provide IPv6 connectivity to all subscribers 10
11 Dual-stack ISP: when is IPv6 connectivity used? Home network Dual-stack ISP Service providers Internet IPv4 traffic IPv6 traffic (i) OS (ii) applications (iii) CPE (iv) ISP connectivity (v) service availability IPv6 upstream and DNS RRs correctly set 11
12 Dual-stack ISP: when is IPv6 connectivity used? Home network Dual-stack ISP Service providers Internet IPv4 traffic IPv6 traffic (i) OS (ii) applicationsfirst we (iii) need CPEto (v) service availability (iv) ISP connectivity understand this chain of connectivity 12
13 Inferring connectivity User devices DNS requests (A & AAAA) IPv6-speaking vs. IPv4-only devices 13
14 Inferring connectivity User devices DNS requests (A & AAAA) CPEs / ISP Local AAAA DNS reqs Global RADIUS (ISP) Obtain an IPv6 prefix and make use of it 14
15 Inferring connectivity User devices DNS requests (A & AAAA) CPEs / ISP Services Local AAAA DNS reqs DNS responses (AAAA) Global RADIUS (ISP) active measurements (connectivity) A service is a Fully-Qualified Domain Name (FQDN) 15
16 Inferring connectivity User devices CPEs / ISP Services Local DNS responses AAAA DNS reqs (AAAA) DNS requeststhat is connectivity, what about traffic? (A & AAAA) Global active measurements RADIUS (ISP) (connectivity) 16
17 Inferring connectivity User devices CPEs / ISP Services Local DNS responses AAAA DNS reqs (AAAA) DNS requeststhat is connectivity, what about traffic? (A & AAAA) Global active measurements RADIUS (ISP) (connectivity) Annotate network flows: <DSLID,FQDN, #bytes> DSLID has IPv6? A request? A RR? AAAA request? AAAA RR? We can now reason about traffic! 17
18 From connectivity to traffic: example (1)? Name server A AAAA :6800:4006:809::2004 (2) Flow: <DSLXY, DSLID has IPv6 A request A RR present AAAA request AAAA RR present IPv6-speaking device uses IPv4 to connect to Google 18
19 Dataset Dual-stack ISP with 12.9K subscribers, 45 h trace (winter 15/16) Trace Total # bytes 64.5TB # flows 356.2M First question: do all subscribers get and use IPv6? 19
20 DSL subscribers Question: Do all subscribers get IPv6? IPv4-only (17%) IPv6 connectivity IPv6 traffic We see AAAA 1) Operator s policy: new contracts get IPv6 2) DNS requests are not always indicative 20
21 DSL subscribers Question: Do all subscribers get IPv6? IPv4-only (17%) IPv6-inactive (30%) IPv6 connectivity IPv6 traffic IPv6 connectivity IPv6 traffic We see AAAA Almost no AAAA CPE does not support/provide IPv6 default conf.? 21
22 DSL subscribers Question: Do all subscribers get IPv6? IPv4-only (17%) IPv6-inactive (30%) IPv6-active (53%) IPv6 connectivity IPv6 traffic IPv6 connectivity IPv6 traffic IPv6 connectivity IPv6 traffic We see AAAA Almost no AAAA IPv6 share is 21% Let s study their interaction with services... 22
23 Questions What is the interplay between connectivity and traffic? IPv6 barriers: services offered on IPv6 but clients accessed on IPv4 IPv6 intent: services offered on IPv4 but clients requested IPv6 When will we see more IPv6 traffic in these networks? 23
24 IPv6 barriers 27% of the overall traffic relates to IPv6-ready services 24
25 IPv6 barriers yet only ~⅓ of that is carried over IPv6! 25
26 IPv6 barriers Why does IPv4 dominate? 26
27 IPv6 barriers 70% due to CPE configuration & ISP policy! 27
28 IPv6 barriers IPv6-active IPv4-only speaking devices & happy-eyeballs fallbacks 28
29 Questions What is the interplay between connectivity and traffic? IPv6 barriers: services offered on IPv6 but clients accessed on IPv4 IPv6 intent: services offered on IPv4 but clients requested IPv6 When will we see more IPv6 traffic in these networks? 29
30 IPv6 intent What is the breakdown by DSL-subscriber type? 30
31 IPv6 intent What if these services would be made available for IPv6? 31
32 IPv6 intent IPv4-only speaking devices? (*) 32
33 IPv6 intent Most traffic could be exchanged over IPv6! 33
34 Questions What is the interplay between connectivity and traffic? IPv6 barriers: services offered on IPv6 but clients accessed on IPv4 IPv6 intent: services offered on IPv4 but clients requested IPv6 When will we see more IPv6 traffic in these networks? Happy eyeballs What-if scenarios 34
35 Happy eyeballs (RFC 6555): fallback to IPv4 Client Name server :db8::1 AAAA? A? :db8::1 TCP SYN, IPv6 TCP SYN, IPv4 TCP SYN+ACK, IPv4 TCP ACK, IPv4 TCP RST, IPv6 Collect TCP handshakes completion times and DNS lookups per FQDN 35
36 Metrics for happy eyeballs (TCP vs DNS resolution) 80% of the times ± 10ms will use IPv6 36
37 Transition to IPv6: What if... Optimistic: IPv4-only devices, happy eyeballs, etc. 37
38 Summary Not every subscriber uses IPv6 connectivity at a dual-stack ISP 1) 2) 17 % of the IPv4 traffic to IPv6-ready services is a result of the ISP policy 53 % of the IPv4 traffic to IPv6-ready services is due to CPEs Devices want IPv6 but many services do not operate on IPv6 yet 1) At least 62% of the traffic to IPv4-only services from IPv6-active DSLs We may see substantial and fast changes in dual-stack networks! 38
39 Thank you! Questions? Home network Dual-stack ISP Service providers Internet IPv4 traffic IPv6 traffic (i) OS (ii) applications (iii) CPE (iv) ISP connectivity (v) service availability 39
