D
Domain Name System resource exhaustion attack(DNS resource exhaustion attack)
An attack in which the attacker continuously queries a name server with the intent of depleting a resource that is essential to the server’s operation. In one type of exhaustion attack, the attacker continuously opens connections on a name server, but does not complete the connection process for any of them. The incomplete connections eventually consume available memory on the name server, preventing it from opening any legitimate connections.
