IPv6 in Spain
These graphs show the evolution of default protocol, v6 address types, and average bandwidth in Spain over time. They are generated using the data collected by tens of thousands of tests that are done monthly at the ipv6-test.com connection test page, and are updated on a monthly basis.
Overall IPv6 and v4 protocol support in Spain
The graph below shows the evolution of IPv6 support vs IPv4 for all our connection test. The numbers are percentages, so we can expect almost 100% of hosts supporting IPv4 with a slow growth for IPv6.

Default browser protocol in Spain
The graph below 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 red bars will grow taller than the blue ones.
Default browser protocol in Spain (dual-stack users)
The graph below 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 Spain
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 Spain
This one 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.
