Google and IPv6

[Sander Steffann]

Hi,

This is the 6to4 address space, which is announced by multiple  
organisations (anycast) for their gateway. Your.org is one of them. It  
might be a good idea for Google to install their own 6to4 gateway.  
That way you are not depending on the Your.org gateway. Then the IPv6  
reply will go from the Google servers directly to the Google 6to4  
gateway, which will send it straight to the public IPv4 address of the  
6to4 router of the user. It will provide the best possible routing,  
and the least number of dependencies on other networks.

6to4 is not easy to debug, but if both sides use a 'local' 6to4  
gateway it's possible.
