Greece IPv6 in Greece

These graphs show the evolution of default protocol, v6 address types, and average bandwidth in Greece over time.

They are generated using the data collected by the ipv6-test.com connection test page, and are updated on a monthly basis.

Overall IPv6 and v4 protocol support in Greece

This graph 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.

IPv6 and v4 protocol support in Greece (unique addresses)

This graph shows the evolution of IPv6 support vs IPv4 for unique users of our connection test.

The numbers are percentages, so we can expect a slow growth towards 50% v4 / 50% v6.

Default browser protocol in Greece

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 Greece (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 Greece

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 Greece

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.
