## Differences between rootful and rootless container networking
-One of the guiding factors on networking for containers with Podman is going to be
-whether or not the container is run by a root user or not. This is because unprivileged
-users cannot create networking interfaces on the host. Therefore, with rootful
-containers, the default networking mode is to use netavark.
-For rootless, the default network
-mode is slirp4netns. Because of the limited privileges, slirp4netns lacks some of
