A client device may have a database that may contain a record of a secure DNS server for one or more hostnames. When a DNS request contains one of the specified hostnames, an authenticated session may be created with the designated secure DNS server and a network address for the hostname is returned using the session. The authenticated session may authenticate a client device to the server as well as authenticate the server to the client. In some embodiments, the secure DNS server may accept connections from authenticated clients and may disregard connection requests from non authenticated clients."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure DNS query","description":"A secure DNS query may be made by establishing a secure connection with a specific DNS server to determine an address for a hostname.
