When you’re starting out with Nerves, you may have connected to your first
projects over the network using nerves.local. Libraries like
nerves_init_gadget make this easy and when you’re
starting out, it’s really convenient. Don’t know the IP address that your
device was assigned? Try nerves.local and you’re good to go.
And then you add a second device to your network. nerves.local isn’t looking
so convenient any more.
