Ce fichier permet de configurer le dhcp, une adresse ip statique ou encore le(s) serveur(s) DNS. Il fonctionne en parallèle avec les fichiers interfaces et wpa_supplicant.conf.

On voit à la fin du fichier de configuration que je demande à avoir l'ip 192.168.1.10 avec un masque de 255.255.255.0 (/24), que le routeur est en 192.168.1.1 et que ce même routeur est aussi DNS.
