Today is the World IPv6 Day. According to the website, the goal of the day is "to motivate organizations across the industry to prepare their services for IPv6 to ensure a successful transition as IPv4 addresses run out."
Unfortunately, my Internet Service Provider does not support IPv6. Anyway, this website should work fine with IPv6 only connections.
