I’m new on networking and I just want to understand, why, when creating a container with Docker, I can connect to the host PostreSQL server using host.docker.internal but not with 172.17.0.1?

Is there a way to use an IP instead of host.docker.internal?

I can ping 172.17.0.1 inside the Docker, so I just don’t understand. I opened the container with the default network (bridge) and opened the PostgreSQL ports, even not needing to do this.

OBS: I’m on Windows
