Global IPv6 End-User Readiness

IPv6 Capable = 22.75 (20190831)245.74% increase in last 36 months!

https://stats.labs.apnic.net/ipv6/ 20190831

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)?

http://www.potaroo.net/presentations/2016-02-22-ipv6-performance.pdf

Routing Path & Performance

IPv4 RTT – 325msIPv6 RTT – 213ms

https://labs.apnic.net/?p=850

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!

• 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/

33

• DHCPv6:– Windows– iOS

• Dual-stack:– KaiOS (Jio handsets)– iOS: reports for dual-stack

since 11.3 (through carrier update)
