In one embodiment, for example, a client apparatus may comprise a data store and a network access component. The data store may be operative to store a network configuration file, the network configuration file containing a client-specific secret. The network access component may be operative to transmit a communication request from the client device to a proxy server, the communication request directed to a destination server distinct from the proxy server, and to receive a response to the communication request from the destination server based on a determination by the proxy server that the client is authorized to use the proxy server, the determination based on the client having previously sent an encoding of a client-specific secret to a domain name server embedded within a lookup domain of a domain name request. Other embodiments are described and claimed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Techniques to authenticate a client to a proxy through a domain name server intermediary","description":"Techniques to authenticate a client to a proxy through a domain name server intermediary are described.
