Ooops.  When IPv6 enabled you should have at a minimum a link local
IPv6 address auto assigned.

Hree is how my pi looks:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP 
qlen 1000
    link/ether b8:27:eb:18:89:b5 brd ff:ff:ff:ff:ff:ff
    inet 204.17.205.17/24 brd 204.17.205.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 2001:470:e815:0:ba27:ebff:fe18:89b5/64 scope global dynamic 
       valid_lft 86390sec preferred_lft 14390sec
    inet6 fe80::ba27:ebff:fe18:89b5/64 scope link 
       valid_lft forever preferred_lft forever


The fe80:... should ALWAYS be there automagically.

The other one, the 2001:470:815:... is my IPv6 net block.  It should
also be there automagically if you have a local IPv6 router and you do
not disable it.  You should never diable it.

As I said, this should be automatic, at least the FE80: one.  If you
did something to prevent that, then don't do that.
