IPv6 deployment is progressing globally with the world average at around 32% capable. In Asia, deployment is highest in South Asia led by India, with over 86% of its internet traffic now IPv6 capable. Other Asian countries like Vietnam and Thailand also show significant deployment levels across their major internet service providers. While progress has been steady, IPv6 uptake remains uneven worldwide and more can still be done to advance the transition.

IPv6 policy proposals
Year Proposals implemented
2004 prop-016: IPv6 allocations to IPv4 networks
prop-021: Expansion of the initial allocation space for existing IPv6 address space holders
2005 prop-031: Proposal to amend APNIC IPv6 assignment and utilisation requirement policy
2006 prop-033: End site assignment policy for IPv6
prop-035: IPv6 portable assignment for multihoming
prop-041: IPv6 assignment size to critical infrastructure
2008 prop-057: Proposal to change IPv6 initial allocation criteria (removing 200 assignments)
2009 prop-073: Simplifying allocation/assignment of IPv6 to APNIC members with existing IPv4
addresses
2010 prop-082: Removing aggregation criteria for IPv6 initial allocations
prop-083: Alternative criteria for subsequent IPv6 allocations
2012 prop-101: Removing multihoming requirement for IPv6 portable assignments
2017 prop-122: Updating “Subsequent IPv6 allocation” policy
prop-121: Updating “Initial IPv6 allocation” policy

The AP region continues to dominate
• From 56 APNIC Economies, in 2018 4 were above average,
7 average and 2 below average:
– 23% of the region’s economies had visible IPv6 capability above 1%
• In 2022, 9 Economies are above average, 10 average and
6 significantly below average, for a total of 25 from 56.
– 44% of the region’s economies are now visible in IPv6 capability
above 1%

Asia
• Significant population of IPv6
– The majority of IPv6 worldwide by
population is in Asia
– Highly dominated by India, but with
large deployments including Viet
Nam, Thailand, Malaysia, Japan

China has moved at scale (slowly)
• Until mid-late 2018 China did not show any real adoption
• Since mid 2018 we see signs across all the major ISPs of
IPv6 adoption
– There are possibilities the mechanisms used by APNIC, Akamai and
Google do not entirely reflect adoption levels inside China, some
ISPs report significantly higher deployment at scale
• China has good targets in state planning
– Trend is upward but pace is low

Taiwan continues to grow at scale
• An initial surge in 2019 has continued at slower pace
• Some significant carriers still don’t show high deployment
• Some markets may be reaching saturation until the next
significant re-capitalization replaces IPv4 only equipment
(CPE?)

Observations
• There has been significant progress since 2018 which appears
to be continuing
• APNIC region is dominant in IPv6 deployment at scale by
population and % capability
– Rising from 52% in 2018 to 66% in 2022
– Higher economy count, deeper participation per economy
• The deployment is not equally spread into all economies
– The variances continue to be very confusing: its not about being a
developed, or developing economy, or size, or amount of ASN diversity
– It may be more about cost of capital and willingness to invest
• Some significant telcos are not deploying at all
