Need some help with IPv6

I've been working on IPv6 for the last 2 hours or so, but i just can not get it working on my server :(

I have the following in my network config:

iface eth0 inet6 static
pre-up modprobe ipv6
address 2xxx:xxx:6:0292::2
netmask 64
gateway 2xxx:xxx:6:0292::1
dns-nameservers 2001:4860:4860::8888 2001:4860:4860::8844

But i still have the

 inet6 addr: fe80::226:2dff:fe16:1d55/64 

Address at the ifconfig results

Also, can not ping6 any host

Can someone help me with this please?
