Default browser protocol in United Kingdom

This graph shows the percentage of browsers that default to IPv6 vs. IPv4 when visiting the ipv6-test connection test.

Hopefully, in the not so distant future, the v6 part will grow taller than the v4 one.

Default browser protocol in United Kingdom (dual-stack users)

This graph shows the percentage of browsers that default to IPv6 vs. IPv4 for users that have both v4 and v6 connectivity.

Usually a system will default to v6 when it's available, but in some cases with tunneled connections, v4 stays the default.

IPv6 address types in United Kingdom

Here you can see the evolution of address types over time, and measure usage of 6to4 and Teredo tunneled connectivity.

It should be noted that because 6rd works with native addresses, it cannot be detected here as tunneled. This is also the case with VPN based tunnels.

Downstream bandwidth in United Kingdom

This graph illustrates the connection speed gap between IPv4 and IPv6, numbers represent v6 speed as percentage of v4 speed.

The lower IPv6 speeds are often caused by tunneling overhead or insufficient v6 connectivity or peering capacity at ISPs.
