What sits between the web client and the web server and is used to prevent IP blocking and maintain anonymity?

• A. Firewall
• B. Load Balancer
• C. Web Proxy
• D. DNS Server

Answer: (C)

Sitting between the web client and the web server, a web proxy acts as an intermediary for requests and responses. The client is configured to send its web requests to the proxy, and the proxy forwards those requests to the destination server, then returns the server’s responses back to the client. Because the server sees the proxy’s IP address instead of the client’s, this can help circumvent IP-based blocks and preserve anonymity to some extent. Proxies can also offer caching and access controls, but their anonymity effect comes from routing traffic through the proxy rather than directly to the server. Firewalls filter and block traffic at the network edge, not primarily for anonymity. A load balancer distributes requests across multiple servers, not for concealing identity. A DNS server translates domain names to IP addresses, which is a name resolution step, not a path element for hiding the client’s identity.
