The invention provides a method and a system supporting domain name group domain name server (DNS) resolution. The system comprises a register data storage device, a resolution generation server and a DNS resolution server. The resolution generation server reads domain name data information of a domain name group from the register data storage device; whether domain names in the domain name group share a DNS or whether standardized domain names are provided is determined, the domain names are configured or corresponding resolution records are resolved, and records are taken; and then the acquired resolution records are transmitted to the DNS resolution server for resolution. According to the method and the system supporting the domain name group DNS resolution, a plurality types of resource records (a network service (NS) record, a domain name CNAME record and a domain name DNAME record) of each domain name in a domain name group are added, a group resolution method is achieved, flexible configuration can be achieved, and resolution and management of a domain name is facilitated.
