摘要

Systems and network devices configured for client-side domain name system (DNS) prioritization using time zone offset to select from configured list of DNS servers. A UE device (DNS client) may determine its current time zone, and query a locally stored domain name system (DNS) server list to select a regional DNS server based on its current time zone. The UE device may send DNS requests for resource addresses to the selected regional DNS server. In response, the UE device may receive DNS response messages that priorities resource addresses based on their geographic proximity to the current time zone of the UE device.

說(shuō)明書(shū)

In block 504, the processor may query a domain name system (DNS) server list to select a regional DNS server based on the current time zone. As part of these operations, the processor may perform the operations discussed above with reference to FIGS. 3-4B (e.g., with reference to blocks 302, 408, 458, etc.). In block 506, the processor may send a DNS request for a resource address to the selected regional DNS server. In some embodiments, sending the DNS request in block 506 may include causing an authoritative DNS to provide regionally tailored responses to specific recursive DNS servers servicing clients in specific time zones. In block 508, the processor may receive a DNS response message from the regional DNS server that prioritizes resource addresses based on their geographic proximity to the current time zone of the UE device. As part of the operations in block 508, the processor may perform the operations discussed above with reference to FIGS. 3-4B (e.g., with reference to blocks 306, 412, 462, etc.).

Various embodiments illustrated and described are provided merely as examples to illustrate various features of the claims. However, features shown and described with respect to any given embodiment are not necessarily limited to the associated embodiment and may be used or combined with other embodiments that are shown and described. Further, the claims are not intended to be limited by any one example embodiment. For example, one or more of the operations of the methods 400, 450 may be substituted for or combined with one or more operations of the methods 400, 450, and vice versa.
