Busca Registro NS
Identifique os servidores de nomes autoritativos para qualquer domínio.
Como Usar Esta Ferramenta
- O Que Inserir
- Enter a domain to find its authoritative NS (Name Server) records and verify DNS delegation.
- O Que Você Obtém
- Lists all NS records with hostnames, resolved IPs, TTL values, and delegation consistency check.
Como Interpretar os Resultados
NS records define which servers are authoritative for a domain. All listed nameservers should return consistent answers. Mismatched NS records between registrar and zone can cause intermittent resolution failures. Most domains use 2-4 nameservers for redundancy.
Problemas Comuns e Soluções
Lame delegation occurs when NS records point to servers that do not host the zone. Inconsistent NS records between the registrar (parent zone) and the domain zone itself cause unpredictable behavior. Single-nameserver setups create a single point of failure.
