Adding ARP to make network discovery of machines

[jorgerobles]

Hi @cprezzi
Could we add ARP network discovery to the server? I've been asked by @DouglasPearless (a DarklyLabs developer) to check candidate machines on local network. I've suggested https://github.com/TheThingSystem/node-arp-a so we can send that addresses to frontend via server like USB devices are done.

From node-apr-a's readme: "That's possible for Linux and Mac OS." The context of this quote is a little unclear. Does node-apr-a support Windows?

Seems to. ARP is a windows command too (https://www.computerhope.com/arphlp.htm). The module unifies ARP answers.

Another candidate is https://github.com/skepticfx/arpjs uses pcap lib
