Which DNS record defines the name servers within your namespace?

Explanation:
Defining the authoritative servers for a domain is done with NS records. These records specify the hostnames of the servers that hold the DNS zone data for your namespace and are authoritative for it. Resolvers use NS records to know where to send queries for that domain, enabling proper delegation in the DNS hierarchy. For example, a domain might list NS records pointing to ns1.example.com and ns2.example.org, which are the servers that answer for that domain’s zone. By contrast, A records map names to IP addresses, MX records indicate where mail for the domain should be delivered, and PTR records support reverse DNS lookups by mapping IPs back to domain names.
