from ipam.models import IPAddress
ip = IPAddress(address='192.168.1.1/24')
ip.save()Device Management
Document devices, their roles, and connections:
from dcim.models import Device
device = Device(name='Router1', device_role='router', device_type='Cisco')
device.save()How might you use these features in your own setup? Share your ideas in the comments!
