              on est bien en ip statique<\/p>\n\n\n\n
                \n
              • si on veux passer en ip dynamique, il suffit de modifier le fichier comme le premier exemple<\/li>\n<\/ul>\n\n\n\n
                \u26a0\ufe0fSi on est sur une machine containeris\u00e9 sous docker ou lxc netplan n’existe pas, l’ip se g\u00e8re au niveau du container<\/p>\n\n\n\n
