new method to get hostnames

[roccomuso]

It would be worth having a method like network.get_hostnames(cb), that returns a map Hostname <--> IP for the current active interface? (parsing the output of arp -a on unix).

You mean like parsing /etc/hosts?

[roccomuso]

Not really. For current machine hostname you have os.hostname(), arp -a provides LAN devices hostnames

Hey @roccomuso. It's been a while, but I was wondering if you're up for submitting a PR for this.

[roccomuso]

Yep, I'm wondering if it's worth creating a new module using ip n as fallback for arp -a.
Moreover the hostname is not guaranteed in the arp table. Most of the times you'll have a simply IP <-> Mac address bind.
