What layer is DNS?
Application LayerIn OSI stack terms, DNS runs in parallel to HTTP in the Application Layer (layer 7). DNS is in effect an application that is invoked to help out the HTTP application, and therefore does not sit “below” HTTP in the OSI stack. DNS itself also makes use of UDP and more rarely TCP, both of which in turn use IP.
