Abstract:
Among other things, this document describes systems, devices, and methods for improving the mapping of end user clients to content servers. In one embodiment, an intermediary DNS server receives a DNS answer with multiple IP addresses. The intermediary DNS server modifies this answer before passing it on to the end user client—that is the end user client that originally requested name resolution of the hostname. Modification can involve filtering the list to remove low-performing IP addresses, re-ordering the list, blocking certain IPs according to policy, or other things. The intermediary DNS server can be operated by a internet service provider (carrier) or an enterprise, for example, or provided on their behalf by a third party as a service. The modification can be based on knowledge of the client-side network, including the location and connectivity of the end user client.

Claim (Index 1):
A method for improving the network performance of an end user client to server connection, comprising:\n at an intermediary DNS server:\n receiving a DNS response comprising a plurality of IP addresses generated by an upstream DNS server in response to a request to resolve a domain name, the request having originated from an end user client; \n wherein each of the plurality of IP addresses is a valid IP address pointing to a live server that is available to serve content hosted under the domain name; \n modifying the DNS response, said modification being based at least in part on a policy defined by any of an internet service provider, a carrier, and an enterprise that provides the intermediary DNS server for the end user client, the modification comprising at least one of:\n (i) re-ordering the plurality of IP addresses; \n (ii) filtering the plurality of IP addresses; \n (iii) substituting an IP address for one of the plurality of IP addresses; \n \n sending the modified DNS response towards the end user client.
