Here's what happens from my machine, connected to noisebridge-a.
At least two other folks have experienced this.

? (172.30.0.2) at 0:0:24:c0:fd:48 on en1 [ethernet]

Also, ping -r 172.30.0.2 (bypasses routing tables and sends directly
to a host on an attached network)
joinglossary-lm:~ thatha$ sudo ping -r 172.30.0.2
