Does Matomo support IPv6 protocol?

Yes, Matomo (Piwik) works well with any IPv6 addresses. Here is further information:

  • Tracking API will track users with an IPv6 address.

  • Visitor Log and other detailed user reports will display IPv6 addresses.

  • IP Anonymisation privacy feature will anonymise IPv6 addresses. For example if Matomo is configured to anonymise « 1 byte » from an IPv4, then the IPv6 address 2001:db8:0:8d3:0:8a2e:70:7344 would be anonymised as 2001:db8:0:8d3:0:0:0:0. When configured to anonymise 2 bytes, then the IPv6 becomes 2001:db8:0:0:0:0:0:0. And when configured to anonymise 3 bytes, then the IPv6 would be 2001:d00:0:0:0:0:0:0.

  • Geolocating IPv6 does not work very well: most IPv6 will not be accurately geo located. A few Ipv6 addresses may be geo-located when using the PHP or Apache geo location driver. IPv6 geo location does not work with the Maxmind PECL driver (issue). Geo locating Ipv6 addresses may improve in the future as DB-IP (our recommended Geo database provider) improves the accuracy of their IPv6 databases.

  • Logs containing IPv6 addresses can be imported in Matomo without any issue and they will be correctly parsed, anonymised (when applicable), stored and processed.

Here is an example of an Ipv6 address: 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
