A method, computer readable medium, and device for providing authenticated domain name service includes forwarding at a traffic management device a request for a domain name from a client device to one or more servers coupled to the traffic management device. The traffic management device receives a first response comprising at least a portion of the domain name from the one or more servers. The traffic management device attaches a first signature to the first response when the first response is determined by the traffic management device to be an unauthenticated response, and provides the first response with the first signature to the client device.
