    Abstract: An approach for mitigating distributed denial of service (DDoS) attacks includes assigning a set of temporary network addresses to a hostname for a finite period and assigning one or more other sets of temporary network addresses to the hostname in one or more following finite periods, responding to a hostname lookup request based on the set of temporary network addresses, the one or more other sets of temporary network addresses, or a combination thereof that are active, responding to a network address lookup request based on at least one of the set of temporary network addresses and the one or more other sets of temporary network addresses that is associated with a current one of the finite period or the one or more following finite periods, and retiring the set of temporary network addresses, the one or more sets of temporary network addresses, or a combination thereof after a configurable number of finite periods, wherein no further network address or hostname lookup request is served based on the retired set of temporary network addresses, the retired one or more sets of temporary network addresses, or a combination thereof.
