IPv6 here and now
I decided to test a little IPv6 on my computer.
I have to say: my provider does not provide a native IPv6 connection. Therefore, to work with IPv6, it took IPv6 traffic to be wrapped in IPv4.
If you have Windows Vista or higher, then you can almost certainly start using IPv6. In these operating systems, Microsoft has embedded the Teredo development protocol itself, which should automatically provide you with an IPv6 Internet connection through a Microsoft server.
If you have Ubuntu or Debian (or another * nix) of a fairly new version, you can install a free implementation of the same protocol using the sudo aptitude install miredo command. It should be noted that the article I read recommended replacing the default server used by Miredo with the Microsoft server: teredo.ipv6.microsoft.com.
')
You can verify that IPv6 is working by sending a ping to ipv6.google.com (“ping -6 ipv6.google.com” in Windows and “ping6 ipv6.google.com” in * nix).
Now a little about your own observations.
Firstly, for some reason, the delay to ipv6.google.com is almost twice as low as the delay to google.com (109ms on average against 244ms). There can be two explanations for this: either the Google server serving ipv6.google.com is less loaded and therefore responds faster or unpopular while ICMPv6 packets are not checked (filtered) by most devices and therefore are transmitted faster.
