(Note that the proxy server can run on different ports, e.g., 80, 8080, 3128.) The proxy IP came from a free proxy list (link below). Note that the arrows in the figure show only the first HTTP packet flow, though it is a bi-directional communication in which the returning packets have the inverse order of source/destination IPs and ports.Īs an example, I opened my What-is-my-IP script at two times: The first one without a proxy and the second one with a proxy on port 3128. In the case of a proxy, the HTTP X-Forwarded-For header with the client IP address might be inserted. In both scenarios, the “Host” value in the HTTP request is set to the requested domain. No DNS query is sent from the client itself. And since it is a “real” proxy, both packets are inside its own TCP connection with different source addresses as well. The second packet is sent from the proxy to the final destination. The requested URI shows the complete URL (host + path). HTTP proxy requests: The first packet is sent to the proxy.Preceding is a DNS request from the client to its configured recursive DNS server. When you try to use HTTP the connection will be redirected to HTTPS. Almost all big website are using HTTPS todays. NBNS traffic is generated primarily by computers running Microsoft Windows or Apple hosts running MacOS.

DHCP traffic can help identify hosts for almost any type of computer connected to your network. That's why Wireshark use TLS and TLS version in protocol column instead of HTTPS. How do we find such host information using Wireshark We filter on two types of activity: DHCP or NBNS.

Direct HTTP requests: Destination IP is the HTTP server and the requested URI shows only the path behind the domain. 2 Answers Sorted by: 3 Wireshark cannot see application data because it is encrypted with TLS.

Following is the main figure for this article.
