Greetings and salutations,

 I`ve been playing around with setting up ipv6 on my router via 6to4 relay server/linux box via a tunnel broker/and setting as the default search engine in my browser.

  Its been lots of fun!

My questions are;
 Is there any advantage in using the ipv6 google search engine over the ipv4 version?
or to put it another way,
 Does the ipv6 engine return search results for ipv6 & ipv4 websites or only ipv6 websites?

TIA   Allan
