> +Question:+
> Fiware Subnet settings in the Fiware Cloud?
> +Description:+
> I have worked through the tutorials and webvideos,
> but some very basic questions about the Fiware cloud remain still open.
> a) When adding a Subnet to the Network,
> How to choose Network Address and DNS name server?
> I mean what is practical? If I make up a Network address, how do I know that it is not taken yet? If I just use 192.168.1.1 does that not connect to any router? Sorry i really don't have a clue there.
> b) Why does network subnet does not accept Admin state and holds it
> after checking it? Is one supposed to keep the admin state checked?
> c) What does "source" mean in the security group rules?
> It is always 0.0.0.0/0. Or could one add here the ip address from
> an outside device, e.g. an external computer connected to the internet / a  potential context provider? So by adding the source here it would be able to communicate with the deployed image?
> d) in some/most tutorials the ports are only opened from
> port number to port number, e.g. 22 to 22, but in the video they are opened e.g. from 1 to 22. Is that an error in the video?
