Just curious why you are being taught how to file IFR Flight Plans for a VFR qualification?
Very simple, FIS INFORMATION commonly closes around SS+30 in these countries allowing NVFR and you will be handled by RADAR during night. RADAR is used to handle IFR & Airliners, so you are on one frequency with heavy metal - and you will be treated equal, Hosiannah! FPL is mandatory für NVFR (almost?) everywhere it is allowed and the instruction for FPL@18 RMK/N VFR-NIGHT states a reporting point compliant with standard routing every 30 minutes. If you try to use VFR waypoints, FPL may pass i.e. Eurocontrol, but you will find out on the second call, that the controller does not know VFR and guides you through IFR waypoints. You could insist you are VFR-NIGHT, but will confuse controller and after a short while, you give up and follow the IFR-light behavior.
