Abstract
An authoritative DNS server receives DNS requests for domains. The authoritative DNS server responds to the requests with address records that include IP addresses that are selected from a larger pool of IP addresses, where a first response to a DNS query for a domain can include IP addresses different from IP addresses included in a second 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 randomly select the IP addresses to include in responses to the requests regardless of the domain.
