Hashing name resolution requests according to an identified routing policy

Hashing name resolution requests may be performed according to an identified routing policy. A query from a Domain Name System (DNS) resolver to lookup a name in a first collection of name records may be received. A hash function may be applied to the name to generate a hash value according to a routing policy for the first collection of name records that determines which name record in the first collection of name records is used to answer the query. A name record in the collection of name records may be identified according to a mapping request for the name record using the hash value and a value for the name record may be returned to the DNS resolver. The value for the name record may identify a second collection of name records to query as part of determining the network address at the DNS resolver.
