The present invention provides a method and system for providing a root domain name resolution service. The method for providing the root domain name resolution service comprises: the DNS resolution records of a plurality of domains within a predetermined area are obtained; according to the resolution records, an authorization information database is set up for each level DNS node; a virtual root node providing the domain name resolution service is activated, and according to the data in the authorization information database, the virtual root node responds to the root domain name resolution request for the domains within the predetermined area. Using the technical solution of the present invention and using the DNS resolution records for the domains within the predetermined area, a DNS authorization information database is established which serves as the data basis for the virtual root node providing the root domain name resolution service, and which automatically provides a DNS root resolution service within the area, thus reducing the internet risk caused by domain name resolution failure within an area when an existing DNS system performs root domain name resolution. |
