Another option is to disguise many source addresses, and attackers will assume that hosts on some of these disguised addresses will not respond to SYN-ACK packets. To implement this method, you need to recycle the addresses on the list of source IP addresses that the server wants to connect to, or make the same modifications to hosts in a subnet.穿过南天门，周青来到凌霄宝殿。Compared with the distributed denial of service attack that directly forges the source address, the reflection attack is more difficult to trace the source of the attack due to the addition of a reflection step.
