Abstract
Techniques for detecting Destination Network Address Translation (DNAT) in network paths. Systems and methods include sending a Hypertext Transfer Protocol Secure (HTTPS) CONNECT request to a proxy in a network path; receiving a response to the HTTP request; monitoring a header of the response to the HTTPS request; and determining that the proxy is a Destination Network Address Translation (DNAT) router based on information in the header. The steps can further include performing a plurality of traces, for a plurality of legs of the network path based on the determining; and aggregating details related to the plurality of legs of the network path to provide a holistic view of the network.
