Proxy Internet Principles Illustrated: 3-Layer Strategy for DNS Leakage Protection and Traffic Encryption

How are proxies 'spied on' online? A chart to understand the principle

When we connect directly to the network, the local device will directly expose the public IP, and all access records can be viewed like a transparent courier box. Using a proxy IP is equivalent to adding a "transit warehouse" in the middle - the outside world can only see the IP of the proxy server, while the real IP and access content are hidden.

However, there are two risk points:
1. DNS requests may go to the local network(caused by default browser settings)
2. Unencrypted traffic may be parsed by intermediate devices(e.g., HTTP clear text transfer)

First layer of protection: system-level DNS lockdown solution

When setting up a global proxy via the ipipgo client, it will automatically force all DNS requests to take the proxy channel. Users who configure it manually need to pay special attention:

It is recommended to prioritize the ipipgo providedCustomized ClientsThe 99%'s misconfiguration problem can be avoided with its built-in DNS lockout feature.

Layer 2 encryption: triple-door design for traffic camouflage

A combination of these encryption methods is recommended for different usage scenarios:

1. base layer: Choose a proxy that supports the SOCKS5 protocol (ipipgo full node support)
2. protocol obfuscation layer: disguise proxy traffic as HTTPS requests (requires client support)
3. application encryption layer: Enable end-to-end encryption in specific software (e.g., encrypted chat tools)

ipipgo's.Intelligent Routing TechnologyIt will automatically match the best encryption scheme according to the current network environment, and will automatically upgrade to AES-256 encrypted transmission in public WiFi environments such as coffee shops.

Third level of validation: five-minute self-check security checklist

After completing the setup, verify the effectiveness of the protection through these three websites:

• DNS leak detection: dnsleaktest.com (three consecutive tests)
• WebRTC detection: browserleaks.com/webrtc
• IP location verification: real-time IP location function on ipipgo official website

When all three test results show a proxy server IP and are consistent with the actual geolocation, the protection system is in effect.

Frequently Asked Questions QA

Q: Why does the phone still show the local carrier after opening the proxy?
A：Check if "Flight Mode Reconnect" function is enabled, some phones will switch back to direct connect when the signal is weak, we suggest to use ipipgo's smart guardian mode.

Q: Does encrypted transmission cause internet slowdown?
A: ipipgo's intelligent routing will automatically adjust the encryption strength according to the current bandwidth, the speed difference in daily use is within 5%, 4K video playback is recommended to choose the "intelligent acceleration" node.

Q: What are the main differences between free and paid proxies?
A: In the case of ipipgo, for example, the paid service providesResidential IP pool rotation,Protocol-level traffic obfuscation,Automatic DNS protectionand other enterprise-grade features, while free proxies usually suffer from high IP duplication and no encryption protection.
