Markop Proxy

A DNS server and SNI proxy server help proxy the HTTP and packet over TLS traffic just with config DNS on the client-side.

What is the SNI Proxy Server?

SNI Proxy Server proxy incoming traffic based on the hostname contained in the TCP session. For example, in HTTPv1 protocol with a Host header to determine the actual destination of packets and TLS protocol with the help of server name extension, the proxy server determines the actual destination.

How does Markop Proxy work?

This flow describe how client send a Http request to example.com server

Client setup Markop DNS server as OS default DNS server
Client OS sends DNS query to Markop DNS server to resolve example.com into IPv4
Markop DNS server checks its white list record and resolve example.com into Markop Proxy server IP
OS sends a Http request to Markop Proxy server IP 5.1. Markop Proxy server parse and analyze the data to extract request hostname(example.com) 5.2. Markop Proxy server sends data into hostname(example.com)
Example.com server sends response to Markop Proxy server
Markop Proxy server sends response to client OS
