what type of dns record is used to delegate a dns zone?

To delegate a DNS zone, a Name Server (NS) record is used. The NS record specifies that a DNS zone, such as "example.com," is delegated to a specific Authoritative Name Server. This record is created in the parent zone and points to the name servers responsible for the child zone. The delegation process involves setting up the NS records for the child zone in the parent zone, indicating the authoritative name servers for the child zone.
