Networks Announcing IPv6 - One Year Later

Mirjam Kuehne

About a year ago, we shared some graphs that showed the percentage of IPv6 enabled networks over time. More precisely, it showed the percentage of Autonomous Systems (ASes) that announced one or more IPv6 prefixes in the global routing table. The results for the five Regional Internet Registries (RIRs) were described in an earlier CircleID post: Uptake of IPv6 in All Regions and on RIPE Labs.

Back when those articles were posted, the percentage of ASes announcing one or more IPv6 prefixes in the five Regional Internet Registry (RIR) service regions were approximately: APNIC 10%, RIPE NCC 8.5%, LACNIC 8.5%, AfriNIC 6% and ARIN 5%.

We looked at the progress since then. In the image below you can see the current status in all regions.

The percentage of IPv6-enabled networks has increased in all regions. Now, the percentage of ASes announcing one or more IPv6 prefixes in the RIR regions are approximately: APNIC 17%, LACNIC and RIPE NCC 14-15%, AfriNIC 11.5% and ARIN 10%.

It is interesting to note that the graphs for most regions show some flattening after a rather steep increase earlier last year (around the time the IANA allocated the last IPv4 address space to the RIRs).

We also looked at the countries with the highest IPv6 penetration worldwide. For more information and other graphs, please refer to the background article on RIPE Labs: Networks with IPv6 - One Year Later. More information about IPv6 can be found on IPv6ActNow.
