Retrieving network mask in Python

Question

How would one go about retrieving a network device\'s netmask (In Linux preferably, but if it\'s cross-platform then cool)? I know how in C on Linux but I can\'t find a way

Answer 1

Using the python pyroute2 library you can get all network element attributes:

from pyroute2 import IPRoute
ip = IPRoute()
info = [{'iface': x['index'], 'addr': x.get_attr('IFA_ADDRESS'), 'mask':  x['prefixlen']} for x in ip.get_addr()]
