They the latest code from git. This behavior has changed recently and
dibbler uses /64 even if /56 was delegated.

It's your loopback, so you may configure on it whatever you want. This
should be safe in general, but you'd get a nice routing loop if someone
sent a packet to an address that belongs to that /64 that you configure
on loopback.

If the code from master works, please let me know about it, ok? It's a
recent change and I haven't tested it myself.
