At AS1, it will either be dropped or a destination unreachable ICMP message will be sent back, depending on the configuration of AS1's routers. If AS1 later decides to drop the route 172.16.0.0 / 16, leaving 172.16.0.0 / 18, 172.16.64.0 / 18, and 172.16.128.0 / 18, the number of routes AS1 announces drops to three.

Thus, for a large number of UDP packets, the victimized system will be forced into sending many ICMP packets, eventually leading it to be unreachable by other clients. The attacker(s) may also spoof the IP address of the UDP packets, ensuring that the excessive ICMP return packets do not reach them, and anonymizing their network location(s).
An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication.
