Thanks for the reactivity.  with 0.3.3, I still have some 'moved' alerts from
an IPv6 routable address to a Link Local one, and some 'moved' alerts 
from an IPv4 routable address to a IPv6 Link Local one.

Also for one misconfigured machine which uses temporary IPv6 addresses
I got 'new station' messages for each new temporary address. I don't
know if this is by design or not. Our policy is to forbid this
kind of obfuscation on that network segment, so I'd rather get a
'moved' notification in this case.
