What is DNS a amplification attack:

• A type of DDoS attack in which attackers use publicly accessible open DNS servers to flood a target with DNS response traffic. An attacker sends a DNS lookup request to an open DNS server with the source address spoofed to be the target’s address. When the DNS server sends the
  record response, it is sent to the target instead.
