How docker networks are handled ?

Does this project support docker network selection per docker? (Internet / no-internet)

I didn’t understand the external DNS name vs local DNS. Both can be different?

If i open up the port then only external access possible otherwise you can use it as internal only. Is that right?

For a minute I was happy as I read “spam” instead of “scam”. I wish it is applicable for spam calls.

Good initiative, lets see how effectively implemented by telecos.
