What Is a Proxy Server?
A proxy server is an intermediary that forwards your internet requests on your behalf. When you connect through a proxy, websites see the proxy's IP address instead of yours.
Types of Proxy Servers
| Type | Description | Anonymity |
|---|---|---|
| HTTP Proxy | Handles web (HTTP/S) traffic only | Low - Passes your IP in headers |
| SOCKS5 Proxy | Handles any TCP/UDP traffic | Medium - No header leakage |
| Transparent Proxy | Used by ISPs/businesses - You may not know it exists | None - Forwards your real IP |
| Elite Proxy | Hides that a proxy is being used at all | High |
| Reverse Proxy | Sits in front of a server, not client - Used for load balancing | N/A |
Proxy vs VPN
- Proxies typically work for specific apps or protocols - VPNs route all traffic at the OS level.
- Most proxies do not encrypt traffic - VPNs always encrypt the tunnel.
- Proxies are faster but less private; VPNs are slower but more secure.
