How can I create dummy virtual network cloud?

Is there any dummy network available on the cloud platform so that I can test my network code?

Sorry, but what do you want to do? I don’t get it.

If you just need some nodes to add, scan a short IP range in the internet :wink:

I want to set up some topology on the cloud. in the topology, i want to use some router,switches, firewall, etc (basically some assets which are available on the real network).
Just want to simulate my actual network on the cloud.
