IPv6 End-User Readiness

IPv6 capable = 23.14%~1010% increase in the last 5 years

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:– Fetches IPv6 URLs (native/dual-stack) over IPv6, device

deemed IPv6 capable– Fetches the dual-stack URL over IPv6, its deemed to prefer

IPv6 • RFC8305 (happy eyeballs) bias?

IPv6 Performance

Enough data collected to analyze IPv6 performance– APNIC Labs

• Is IPv6 as robust as IPv4?

– Do all TCP connection attempts succeed?

• Connection failure = no ACK for an SYN

– IPv4 connection failure sits at 0.2%

– IPv6 connection failure sits at 1.6% (8 times higher!)

• PMTUD (ICMPv6 filters)?

2020

IPv6 Performance

• Is IPv6 as fast as IPv4? (IPv6 unicast)

– Comparison of RTT (not implicit RTT)

• 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)?

– TechArk measured IPv6 performance for HTTP traffic

• IPv6 performance better when measuring nearer targets!

Routing path & performance

IPv4 RTT – 325msIPv6 RTT – 213ms

Three-stages of IPv6 Growth

Fast growth driven by single, early market driver• Incld. Australia, Bhutan, South Korea, Taiwan

Initial roll-out followed by spread to other Internet Service Providers• Incld. India, Sri Lanka, Thailand, Viet Nam

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

22

2323

• 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

Motivation for Early Market Drivers

2424

• 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!

Industry trend: Who is in control?

IPv6 and Mobile devices

• 464XLAT:– Android (4.4 - KitKat)

– Windows Phone (8.1+)

• IPv6-only:– iOS

• since iOS 9 (supported Ion WiFi for a long time)

• since June 2016, apps in App Store must support IPv6 https://developer.apple.com/support/ipv6/

• DHCPv6:– Windows

– iOS

• Dual-stack:– KaiOS (Jio handsets)

– iOS: reports for dual-stack since 11.3 (through carrier update)

Where are we now?"IPv6 has emerged from the ‘Innovators’ and ‘Early Adoption’ stages of deployment, and is now in the ‘Early Majority phase”

– ISOC State of

IPv6 Deployment (2018)

• Global IPv6 end-user readiness is 18.82%

• 61.6% of network operators in the Asia-Pacific have IPv6 resources.

• IPv6 end-user readiness is increasing (across diverse economy profiles).

• Common trend sees three stages of economy readiness.

• Mobile driven growth of IPv6 deployment

• Observed preference for dual-stack transition technology in recent deployments (PDP

licensing?)

• Positive signs for future readiness growth, especially as vendor support grows
