List of IP addresses/hostnames from local network in Python

Question

How can I get a list of the IP addresses or host names from a local network easily in Python?

It would be best if it was multi-platform, but it needs to work on Mac

Answer 1

For OSX (and Linux), a simple solution is to use either os.popen or os.system and run the arp -a command.

For example:

devices = []
for device in os.popen('arp -a'): devices.append(device)

This will give you a list of the devices on your local network.
