Where are we now?
APNIC Technical Workshop

Kolkata
Hosted By:
Agenda
• IPv6 End-user Readiness
• IPv6 Performance
• Industry Trends
• Observations
Global IPv6 End-User Readiness
IPv6 Capable = 21.47 (20/05/2019)
274.04% increase in last 36 months!
https://stats.labs.apnic.net/ipv6/ 20190520
IPv6 Capable vs Preferred
• Uses scripted online advertisement
– Over 7-10M measurements/day!!
• The Ad script fetches three URLs
– IPv4 only URL, IPv6 only URL, Dual-stack URL
• If:
– compare the number of end devices that can retrieve the V6-only
object to the number of devices that can retrieve the V4-only object
(IPv6 capable)
– the number of end devices that use IPv6 to retrieve the Dual Stack
Object (IPv6 preferred) RFC8305 (happy eyeballs) bias?

IPv6 Performance
• Is IPv6 as robust as IPv4:
– Do all TCP connection attempt succeed?
• Connection failure = No ACK for acknowledged SYN
– IPv4 connection failure sits at 0.2%
– IPv6 connection failure sits at 1.8%
http://www.potaroo.net/presentations/2016-02-22-ipv6-performance.pdf
IPv6 Performance
• Is IPv6 as fast as IPv4? (IPv6 unicast)
– Comparison of RTT (e2e)
• Time since SYN till ACK (factors out any congestion issues)
– IPv6 is faster about half of the time • 45ms faster (36-90ms)
• NAT?
• IPv4 and IPv6 using different paths (different peering policies for IPv4 and IPv6)?

Routing Path & Performance
IPv4 RTT – 325msIPv6 RTT – 213ms

IPv6 Performance
• Testing HTTP Traffic
– TechArk Network Operat or Measurement Activity (NOMA) conducted
preliminary tests of IPv6 performance for HTTP traffic using RIPE
Atlases.
– Found performance of IPv6 is better when measuring to a “near”
target

IPv6 in Action: Performance
• IPv6 at LinkedIn
– For some select networks in Europe, LinkedIn is seeing up to 40%
performance improvements over IPv6, and in the US, up to 10%.
– TCP timeout on IPv4 over mobile carrier networks is as high as 4.6%
and IPv6 timeouts are on a much lower side at 1.6%.

Motivation for Early Market
• Simplify network design
• Commitment to Internet Tech Evolution
• Government Encouragement
• Capability to support growth, IoT, Smart Cities, future
services
• Reduce load on CGN
• Lower CAPEX
Three-stages of IPv6 Growth
• Fast growth driven by single, early
market driver
– Incld. Australia, Bhutan, South Korea
• Initial roll-out followed by spread to other Internet Service Providers
– Incld. India, New Zealand, Sri Lanka, Thailand, Viet Nam, Taiwan
South Korea
• Mature IPv6 market with rich availability from access providers and deployment by providers of Internet services (incld. content, cable TV, cloud)
– Incld. Japan, Malaysia, Singapore

Industry trend: Who is in control?
• Mobile is driving the internet
• However, born and raised on NAT!
– Still heavily based on CG-NAT
• The true driver for IPv6 adoption is mobile internet!
