US 2013/0173769 A1 · SYSTEM AND METHOD FOR RESOLVING A DNS REQUEST USING METADATA

Abstract

A system and method for resolving a DNS request using metadata. An intelligent name server receives a request to resolve a domain name via a network. The intelligent name server acquires at least one metadata element about the source of the request. The domain name request is transformed into a CNAME request that includes the at least one metadata element and the domain name to be resolved. The CNAME request is sent to a metadata aware DNS server for resolution. The metadata aware DNS server maps the domain name to one or more network addresses stored in a look-up table. The included metadata is used to select a “best” host address to include in a response.

Dependent claims

A method for resolving a domain name system request comprising:

receiving at an intelligent name server a request to resolve a domain name via a network, wherein the intelligent name server comprises a first processor;
acquiring by the first processor at least one metadata element about the source of the request;
transforming by the first processor the domain name request into a CNAME request, wherein the CNAME request comprises the at least one metadata element and the domain name;
and
sending by the first processor the CNAME request to a metadata aware DNS server for resolution.

A system for resolving a domain name system request comprising:

a network;
a metadata aware server connected to the network;
an intelligent name server connected to the network, wherein the intelligent name server comprises a first processor configured with software executable instructions to cause the intelligent name server to perform operations comprising:
receiving a request to resolve a domain name via the network;
acquiring at least one metadata element about the source of the request;
transforming the domain name request into a CNAME request, wherein the CNAME request comprises the at least one metadata element and the domain name;
and
sending the CNAME request to the metadata aware DNS server for resolution.
