Abstract
An authoritative domain name system (DNS) server receives DNS requests for domains. The authoritative DNS server transmits DNS responses to the DNS requests with address records that include IP addresses that are selected from a larger pool of IP addresses, where a first DNS response can include IP addresses different from IP addresses included in a second DNS response for the same domain. Also, the same IP addresses may be returned for a first domain and a different, second domain. The authoritative DNS server may select the IP addresses to include in DNS responses to the DNS requests using a round-robin process.
