Aspects of the present disclosure involve systems, methods, computer program products, and the like, for providing a proxy server or scrubbing service for an authoritative domain name server (DNS) of a CDN to prevent or otherwise mitigate attacks on the server. The proxy server may receive incoming requests to the authoritative DNS and determine which requests are valid and which are potentially part of an attack on the network. In one embodiment, the proxy server may then 'scrub' or otherwise remove the requests of the attack to mitigate the effect of the attack on the network. For example, the proxy server may ignore the request, may direct the request to a “dead-end” server or other device to prevent overloading of the target device, may instruct a device from which the request was sent to discard the request, etc.
