Import library

import netifaces

Gate gateway information

We can use netifaces.gateways() to get the gateway information.

# gets gateway of the network
gws = netifaces.gateways()
print(gws)

gws is:

{2: [('192.168.1.1', '{0D61DA8C-6081-4A86-9CAB-E53126A2404D}', True)], 'default': {2: ('192.168.1.1', '{0D61DA8C-6081-4A86-9CAB-E53126A2404D}')}}

Then we can get the default gateway ip.

Get the default getway ip

gateway = gws['default'][netifaces.AF_INET][0]
print(gateway)

Run this code, we will get ip:

192.168.1.1
