US Patent 10178195 Origin server protection notification

An origin server has been registered, or is in the process of being registered, for a proxied service that includes changing Domain Name System (DNS) configurations such that certain network traffic is proxied at a proxy server instead of that traffic being received directly at the origin server. The service checks the configuration and determines if there is any flaw in the configuration that may cause information about the origin server (e.g., the IP address of the origin server) to be leaked. Upon finding a flaw in the configuration, the service may notify the origin server and/or the operator of the origin server that the information may be leaked.
