Découvrez quels serveurs de noms répondent pour un domaine : la première chose à vérifier après un changement de fournisseur DNS.
NS records delegate a domain to the servers that hold its DNS records. If they still point at your old provider, any change you make at the new one will be ignored.
Registries publish the new delegation quickly, but resolvers can cache the old NS set for the parent zone’s TTL, often up to 48 hours. Use the vérificateur de propagation with type NS to watch the switch.
At least two, ideally on separate networks. Most providers give you two to four.
Yes. If a subdomain is delegated elsewhere it will have its own NS records. If not, you will see “no records” – look up the parent domain instead.
Donnez à votre site, serveur personnel ou prochain projet une adresse mémorable : yourname.uk.app. Choisissez un nom et vérifiez sa disponibilité avant de l’enregistrer.
