REQUEST ROUTING UTILIZING CLIENT LOCATION INFORMATION
First Claim
1. A computer-implemented method comprising:
- as implemented by one or more computing devices configured with specific executable instructions;
obtaining a DNS query from a client computing device at a first DNS server, wherein the DNS query corresponds to a requested resource associated with an original resource identifier provided by a content provider and wherein the first DNS server corresponds to a content delivery network (CDN) service;
obtaining a query IP address associated with the DNS query at the first DNS server;
obtaining a confidence factor corresponding to a degree of confidence associated with a location-based identifier to query IP address association; and
processing the DNS query based on evaluation of the confidence factor.

Abstract
A system, method, and computer-readable medium for request routing based on client location information are provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a resource identifier for requested content from the client computing device. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The alternative resource identifier is selected as a function of client location information. The client location information is obtained from information corresponding to a mapping of at least partial IP addresses to known locations. The client computing device then issues a second DNS query to the same content delivery network service provider. The content delivery network service provider can then either resolve the second DNS query or transmit another alternative resource identifier.

9. A system for request routing comprising:
a first network point of presence associated with a content delivery network (CDN) service provider, wherein the first network point of presence includes a first DNS server that receives a DNS query from a client computing device, wherein the DNS query corresponds to a requested resource associated with a first resource identifier provided by a content provider, and wherein the first DNS server in the first network point of presence comprises at least one computing device associated with a memory and is operative to; obtain a query IP address associated with the DNS query at the first DNS server; obtain a confidence factor corresponding to a degree of confidence associated with a location-based identifier to query IP address association; and process the DNS query based on evaluation of the confidence factor. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A non-transitory, computer-readable storage medium comprising one or more computer-executable components for managing DNS queries, the one or more computer-executable components configured to be executed by one or more processors of a computer system to cause the computer system to:
-
obtain a DNS query from a client computing device at a first DNS server, wherein the DNS query corresponds to a requested resource associated with an original resource identifier provided by a content provider and wherein the first DNS server corresponds to a content delivery network (CDN) service; obtain a query IP address associated with the DNS query at the first DNS server; obtain a confidence factor corresponding to a degree of confidence associated with a location-based identifier to query IP address association; and process the DNS query based on evaluation of the confidence factor. - View Dependent Claims (18, 19, 20, 21)
