The invention relates to a domain name resolution method, server and system. The domain name resolution method comprises: receiving a domain name service request from a terminal device, wherein the domain name service request is sent when a user accesses a network, the domain name service request comprises a user IP address and a domain name to be resolved; searching the IP address field in a local domain number resolution server corresponding to the user IP address under the condition that the domain name service request is HTTP format; and searching the service IP address corresponding to the domain name to be resolved according to the IP address field. The domain name service request is directly resolved through the domain number resolution server locally; if the resolution is successful, the IP address can be resolved accurately; a user can quickly and conveniently access to the webpage to obtain service based on the IP address; because the server of an ISP (Internet Service Provider) is bypassed, the accuracy of the resolution result is improved without buffering the domain name and forwarding the resolution request.
