Reduction of perceived DNS lookup latency

摘要

Perceived domain name service (DNS) lookup latency can be reduced for the user of a browser program. A server determines domain names that the user is likely to request in the future. In one implementation, a list of these domain names is transmitted to the browser program as a separate command. The browser program may then lookup up the domain names in the background before the user selects a link corresponding to the domain names. In another implementation, the domain names are transmitted to the browser program by embedding the domain names in a web document, in which the embedded information is not visible in the rendered version of the web document.

1. A method comprising:
transmitting, by a device, a search query to a search engine,
the search query being input by a user; receiving, by the device, a response to the search query from the search engine,
the response including a plurality of domain names associated with documents identified by the search engine based on the search query; pre-resolving, by the device, a subset of domain names, of the plurality of domain names, included in the response based on an order,
the order being determined based on historical data associated with the user, andthe subset of domain names being associated with a subset of the documents; and displaying, to the user, a link to each document of the subset of the documents based on pre-resolving the subset of domain names.
