Abstract: A method for domain name resolution is provided, applied to a system for domain name resolution deployed in a scheduling cluster. The system includes a scheduling system, a probe system, and an analysis system. The scheduling system receives each query request from each DNS server, records each egress IP address of each local DNS server to generate a list of IP addresses to be probed, and reports the list of IP addresses to the probe system. The probe system distributes the list of IP addresses to each probe to probe each of IP addresses in the list through each probe. And the analysis system receives each probing result fed back by each probe, sets each authoritative DNS server for each local DNS server, and processes each domain name resolution request sent by each local DNS server through each authoritative DNS server.
