**FREE**Open Source** Netbox Network Scan Using Pynet |Python
#This script is used to scan the IP addresses in the network for the netbox to discover all subnets with the environment
#Prerequisites - This needs to be done on netbox server

Define the network to scan

Create the object
for network in my_network_list:

Run the scan of hosts using pings
my_scan.run()

To run the scanner and start scanning the network : Make sure you are in the scripts folder.
python3.8 netbox_scan_ip_subnet.py
