How does networking between several “services” (containers) work?

The container opens a gateway and each container provides its own local IP (e.g. 192.168.64.2), from what I understood, every services known host machine and can communicate with each other.

On my current implementation, I didn't work with DNS/Network Resolution because I need to understand better what I can/can't do with the API Apple provides, so the only things it does is handling the port mapping using `socat`, as the docs recommends.
