Problème de configuration DNS

Bonjour, je suis développeur web et je souhaite faire un DNS or je ne suis pas un spécialiste mais j'aime le réseau.
Je n'arrive pas à configurer mon DNS.
J'obtiens des erreurs quand je fais des nslookup et des host nomdemachine.
Je crois c'est pas la peine de trop baratiner voici les fichiers de configuration, si y aurait un courageux pour m'expliquer pourquoi ça ne marche pas.
En tant cas merci bcp d'avance, perso je n'arrive pas à avancer après vérif et revérfi.

ma machine s'appelle "debian" et mon DNS que je souhaite faire est somex.local*

// logic to all top level domains, and to the root domain. An exception list
// should be specified, including "MUSEUM" and "DE", and any other top level
// domains from whom undelegated responses are expected and trusted.
// root-delegation-only exclude { "DE"; "MUSEUM"; };
