A DDoS attack handling technology is provided in which even when a plurality of IP addresses are attacked at the same time, resource load distribution between sites can be achieved while an increase in delay of target-addressed communications due to the handling of DDoS attacks is prevented. A DDoS handling apparatusincludes a load distribution determination unitthat determines whether load distribution processing is necessary, a processability determination unitthat determines whether load distribution processing is capable of being performed within a desired time, a grouping processing unitthat groups target-addressed communications into a plurality of groups, a load distribution processing unitthat determines, for each group, a mitigation site to be used to handle the target-addressed communications from among a plurality of mitigation sites, and an attack handling setting unitthat performs route control of the target-addressed communications. The DDoS handling apparatusfurther includes a load distribution target reduction unitthat reduces the number of the target-addressed communications that are targets of the load distribution processing.
