Does NOT include a trailing /p2p/ with our PeerId.

source

pub fn network_state(&mut self) -> NetworkState

Get network state.

Note: Use this only for debugging. This API is unstable. There are warnings literally everywhere about this. Please don’t use this function to retrieve actual information.
