While WebRTC technology provides browsers with convenient real-time communication capabilities, it also brings the risk of exposing real IP addresses. This article comprehensively explains WebRTC real IP leak prevention, from technical principles and protection strategies to practical operations and enterprise applications, and introduces how to effectively detect and protect using the ToDetect tool.

1. Causes and Risks of WebRTC Real IP Leaks

WebRTC performs peer-to-peer communication directly through the browser, using STUN servers to obtain network information. Even with a VPN, WebRTC may access local or public IPs.

Leak Types:

• Local network IP leak

• Public IP leak

• IPv6 leak

Potential Risks:

• Privacy tracking: Users' online behavior and location may be identified

• Geolocation exposure: Affects cross-border e-commerce pricing, taxes, and logistics displays

• Potential network attacks: Hackers may attack via exposed IPs

2.Comprehensive WebRTC Protection Strategies

1. Disable WebRTC

Most browsers (Chrome, Firefox, Edge) allow users to disable WebRTC in settings.

**Advantages:** Completely prevents WebRTC leaks
**Disadvantages:** May affect video calls, online meetings, and other functions

2. Use Leak-Prevention Extensions

Recommended extensions: WebRTC Leak Prevent, uBlock Origin, etc.

**Advantages:** Prevents IP leaks while maintaining WebRTC functionality
**Suitable for:** Regular users and light office environments

3. Configure VPN and Firewall

• Choose a VPN with WebRTC protection: Ensure STUN requests are routed through the VPN

• Firewall settings: Restrict WebRTC-related ports or IP access

**Advantages:** Enhances network-level protection, suitable for enterprises or high-security users

4. Regular Testing and Monitoring

Single-layer protection cannot guarantee long-term security; regular testing is necessary.

ToDetect Tool Advantages:

• Real-time WebRTC leak detection

• Provides detailed IP leak reports

• Can be monitored regularly to detect protection gaps promptly

3. Enterprise and Cross-Border E-Commerce Protection Considerations

For cross-border e-commerce platforms:

• IP leaks may cause inaccurate pricing, logistics, and tax displays

• If user privacy is exposed, GDPR or other international regulations may be triggered

Solutions:

• Integrate ToDetect API into the platform

• Regularly test visitors' IP leak risks

• Combine with firewall and VPN strategies to ensure user privacy

4. Common WebRTC Protection Questions

1. Will WebRTC protection affect browser functionality?

• Disabling WebRTC may affect video calls and online meetings

• Using leak-prevention extensions is recommended to balance functionality and privacy

2. Can VPN fully prevent WebRTC leaks?

• Regular VPNs cannot fully protect

• Choose VPNs with WebRTC protection and combine with ToDetect for regular testing

3. How can enterprises prevent visitor IP leaks?

• Enterprises can use ToDetect to monitor visitor IPs

• Combine with firewall and VPN strategies to ensure privacy compliance

4. How to verify if protection strategies are effective?

• Use ToDetect for WebRTC leak testing

• Ensure the real IP is not exposed

5. Conclusion

WebRTC protection concerns not only personal privacy but also enterprise compliance. Multi-layered strategies can effectively protect:

• Disable WebRTC

• Use leak-prevention extensions

• Configure VPNs and firewalls with WebRTC protection

• Regularly test with ToDetect

A multi-layered protection system ensures network privacy and data security for both individuals and enterprises.
