ping

I have 2 linux box configured with IPv4. I have tried adding IPv6 to them. I have issued this commands on box1:

ip -6 addr add fd32:2d7f:f3c1::1/48 dev eth0

And I get this:

inet6 addr: fd32:2d7f:f3c1::1/48 Scope:Global

Then I have issued this command on box2:

ip -6 addr add fd32:2d7f:f3c2::1/48 dev eth0

Back on box1 (command/response):

ping6 fd32:2d7f:f3c1::1
 is alive!
ping6 fd32:2d7f:f3c2::1
ping6: sendto: Network is unreachable

Why doesn't box1 ping box2 (of course, also box2 can't ping box1)?
