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

If you know the names of your computers you can use:

import socket
IP1 = socket.gethostbyname(socket.gethostname()) # local IP adress of your computer
IP2 = socket.gethostbyname('name_of_your_computer') # IP adress of remote computer

Otherwise you will have to scan for all the IP addresses that follow the same mask as your local computer (IP1), as stated in another answer.
