Review comment:
Making sure I get it...
* Binds a socket on a random local port (ideally 127.0.0.1 for ipv4)
* This creates an InetAddress to 1.1.1.1
* Tries to bind to 1.1.1.1 on port 0 (what does that actually do?)
* Pulls the network interface used to do that bind, which is what we
actually want
Any downside on this? Does it require being connected to the internet to
work?

Review comment:
Is there a reason we can't use `InetAddress.getLocalHost()` instead of
something on the public internet?
