NS Record
A DNS record that specifies which nameservers are authoritative for a domain.
An NS (Name Server) record tells the DNS system which nameservers are responsible for answering queries about your domain. When a DNS resolver needs to find records for your domain, it follows the NS records to find your authoritative nameservers. If you switch to Cloudflare or a new hosting provider, you change the NS records at your registrar to point to the new nameservers. NS records exist at every level of the DNS hierarchy, from root servers to TLD servers to your domain.
