How Proxies and VPNs Differ<\/span><\/h2>\n

Both proxy servers and Virtual Private Network (VPN) technologies help protect a user’s identity while online and assist companies in safeguarding their networks from potentially harmful traffic.<\/span><\/p>\n

Also known as intermediary servers, <\/span>proxy servers<\/strong><\/span> primarily aim to hide IP addresses, but can also be used for content filtering, caching, load balancing, and security checks. <\/span><\/p>\n

A <\/span>VPN<\/strong><\/span>, on the other hand, not only masks IP addresses but uses encryption to make data and activities completely inaccessible to third parties. <\/span><\/p>\n

How Proxy Servers Work<\/span><\/h2>\n

All online communication involves sending and receiving data to IP addresses in the form of requests and responses. <\/span><\/p>\n

For example, the process for accessing content from a <\/span>web server<\/span><\/a> via direct network connection – both client and server have direct access to each other’s IP address – would look like this:<\/span><\/p>\n

    \n
  1. \n

    Request Initiation:<\/strong><\/span> The client (user’s device) starts by requesting access to the web content hosted on the web server.<\/span><\/p>\n<\/li>\n

  2. \n

    DNS Resolution:<\/strong><\/span> The DNS (Domain Name System) locates the web server’s IP address and sends it to the client.<\/span><\/p>\n<\/li>\n

  3. \n

    Connection and Request:<\/strong><\/span> The client uses the IP address to connect to the web server and sends a request for the content.<\/span><\/p>\n<\/li>\n

  4. \n

    Server Response:<\/strong><\/span> The web server responds by sending the requested content back to the client’s IP address.<\/span><\/p>\n<\/li>\n<\/ol>\n

    Introducing a proxy server into this process disrupts the direct network connection by adding an intermediary between the client and server. This intermediary masks the outgoing IP address from either client side (forward proxy) or the server side (reverse proxy), or both. <\/span><\/p>\n

    Forward Proxy (Client-Side)<\/span><\/h3>\n

    When a client requests access to web content using a forward proxy, they are effectively telling the proxy server to send the request to the web server on their behalf using the proxy’s IP address. <\/span><\/p>\n

    Here’s a breakdown of that process:<\/span><\/p>\n

      \n
    1. \n

      Client Connects to Proxy Server:<\/strong><\/span> The client establishes a connection with the proxy server.<\/span><\/p>\n<\/li>\n

    2. \n

      Client Request:<\/strong><\/span> The client sends a web request to its proxy server.<\/span><\/p>\n<\/li>\n

    3. \n

      DNS Resolution:<\/strong><\/span> <\/strong>The proxy server uses DNS to obtain the web server’s IP address.<\/span><\/p>\n<\/li>\n

    4. \n

      Proxy Server Request:<\/strong><\/span> The proxy server sends the request to the web server using its own IP address.<\/span><\/p>\n<\/li>\n

    5. \n

      Web Server Response:<\/strong><\/span> The web server responds and sends the requested content to the proxy server’s IP address.<\/span><\/p>\n<\/li>\n

    6. \n

      Proxy Server Forwards Response:<\/strong><\/span> The proxy server receives the web server’s response and forwards it to the client through the existing connection.<\/span><\/p>\n<\/li>\n<\/ol>\n

      Throughout this process, the web server never connects to or is even aware of the client’s actual IP address. It believes the proxy server is the end client the entire time.<\/span><\/p>\n

      Reverse Proxy (Server-Side)<\/span><\/h3>\n

      Reverse proxy servers intercept client requests before forwarding them to the host server. In addition to IP masking, reverse proxies can perform several tasks for the host server, including:<\/span><\/p>\n
