Yeah, would you open a GitHub issue?
I tried my two Macs, and it breaks for me, but differently: they get
link-local IPv6 addresses from mDNS, requiring an interface identifier,
so mosh-client doesn't know where to send packets.
I'm wondering how you're getting global IPv6 addresses from mDNS, even
though both your client and server are on the same local network.
Judging by the hostnames you're using and the IPv6 address, this is a
corporate OS X install on $yourverylargecompany's network.
If the server involved has regular DNS A/AAAA records, does that work
with Mosh?
