# IPv6 readiness by country and city

Canonical pages: https://test-ipv6.run/#world-map, https://test-ipv6.run/country/{ISO code} (for example https://test-ipv6.run/country/DE) and https://test-ipv6.run/city/?c={ISO code}&city={name}.

The home page has a world map and a region browser of IPv6 readiness. Each country and city page shows aggregated results from tests run on test-ipv6.run by visitors in that place: the number of tests, the share with working IPv6, average scores, top cities and a regional comparison.

## Limits
- The data come only from visitors who chose to run the test, so they are a sample of this site's audience, not a census of a country's networks. Places with few tests can swing widely.
- Numbers change as new tests arrive; read the live page for current values and do not quote figures from memory.
- Country and city are derived from the visitor's IP address and can be wrong for VPN and mobile users.

For official national IPv6 adoption statistics, compare with sources such as Google's IPv6 statistics or APNIC Labs measurements.
