IPv6 measurement by AS Number


This page lists the IPv6 measurement per AS number, with a 30 day average on the ranking to reduce the impact of occasional-measurement AS such as conference shownets, and collections of few points but with relatively high IPv6 preference ratio.

The ranking is based on the IPv6 preference for IPv4 addresses with the given AS as origin-AS, based on the BGP data for the period of the sample. Where insufficient samples exist to reliably plot the AS for a given period, is considered to have no samples. This exclusion limit is currently set at 200 samples.

The iso3166 economycode of each AS based on its registration is also listed.

Columns for numeric and alphabetic fields are sortable.

A non-truncated list of all ASN seen in the experiment is also available as .csv and .json data below:


About the graphs

These graphs have been rendered using the Google Chart Tools.

The average number of events per week is shown in the graph. Where less than 200 events are seen, the graph supresses data since the results would be unreliable. Since some economies are not seen frequently, their graphs can be empty if all weekly sample sets are below the threshold. Data is still available in the appropriate CSV and JSON files.

These pages show the results of the APNIC Labs collection organized by Geographical divisions taken from UNData Each measurement has been mapped to the economycode of registration against the most specific encompassing IP address block, as noted by published RIR public data. These economycode summaries are then combined into the UN Region according to the list of economycodes provided in each case.

The 3 digit numeric codes are the ISO 3166 3 letter codes, augmented by the UN Data section with specific codes for each region. Some regions do not have codes assigned. Footnotes at the UNData web page also explain why some economies are removed from Geopolitical Regions.


This measurement activity is being undertaken by APNIC, the Asia Pacific Network Information Centre, as a service to the Internet community at large.

We would like to acknowledge the generous support that has been provided by Google, the Internet Society, the Internet Software Consortium and the RIPE Network Coordination Centre in undertaking this activity.
