    摘要: A DNS query method includes receiving, by a first communication device, a DNS query to obtain an FQDN; sending, by the first communication device, first information to a second communication device, where the first information includes the FQDN or N server IP addresses corresponding to the FQDN, and N is a positive integer; obtaining, by the first communication device, server experience information corresponding to the N server IP addresses from the second communication device, where the server experience information is used to indicate service experience of a server corresponding to each of the server IP addresses; and sending, by the first communication device, a DNS response to a terminal based on the server experience information.

    摘要: Methods, apparatus, systems, and articles of manufacture are disclosed to identify devices. An example apparatus to identify devices comprises at least one memory; machine readable instructions; and processor circuitry to at least one of instantiate or execute the machine readable instructions to: determine if a device identification repository includes a first device identifier included in a query; infer first device information for the first device identifier based on a second device identifier and second device information included in the device identification repository; and transmit the first device information in response to the query.

    摘要: A DNS resolution request for a hostname of a CDN is received. An edge server of the CDN may be identified, which may be associated with a subnet. The subnet is used to generate a response IP address, where the remaining bits of the response IP address may be used to store requestor information (e.g., a requestor IP address). When a client computing device uses the response IP address to access the edge server, requestor information is extracted and associated with client computing device information (e.g., an IP address and/or location, etc.) in an association record. Association records may be used to determine predicted characteristics for devices served by a requestor. When the authoritative DNS server resolves a request from the requestor, such predicted characteristics may be used rather than relying solely on information about a requestor. Thus, an edge server proximate to the predicted location may be returned instead.
