A method and a server of remote information query are disclosed. The method includes receiving a query request sent by a client side and acquiring content of a type field of the query request; acquiring a type of the query request based on the content of the type field; adding a type identifier corresponding to the type and a domain name of a preset authorized DNS (Domain Name System) to the query request to acquire a target query request; and sending the target query request to a local DNS to enable the local DNS to send the target query request to the preset authorized DNS according to the domain name of the preset authorized DNS in the target query request, and receiving a response message corresponding to the type of the query request from the preset authorized DNS. Thus, a simpler and highly efficient recognition of user security can be realized.
