What is NS record?

An NS (Name Server) record is a type of DNS record used to specify the authoritative name servers for a domain. It designates which DNS servers are responsible for handling queries related to the domain and its subdomains.

Key Points

  • Delegation: NS records are critical for delegating authority to other DNS servers.
  • Redundancy: It's common practice to have multiple NS records for fault tolerance.
  • Propagation: Changes to NS records can take time to propagate across the internet due to DNS caching.

By defining NS records properly, domain administrators ensure that DNS queries are routed to the correct servers and that domain information is managed effectively.
