The real limiting factor for a single attacker who uses spoofing attacks is that if these spoofed packets can be traced back to their real addresses in some way, the attacker will be simply defeated. Although the backtracking process requires some time and cooperation between ISPs, it is not impossible.

As shown in FIG. 3, these host groups can use direct attacks or further let each host use spoofing attacks.9.
