📖 FAQ

💡 Metrics & Result Disclaimer

Are these results accurate?

All test results shown are obtained by querying authoritative third-party databases in real-time. All results are for reference only.

What are IPv4 and IPv6? Why does IPv6 leak my real IP while IPv4 is proxied?

Many proxies only handle IPv4 traffic. IPv6 traffic bypasses the proxy entirely.
Enable 'Block IPv6' in your proxy software.

How accurate is the IP location?

For reference only. For Residential IPs, accuracy is limited to the city level.

What are ASN, ASN Owner, and Enterprise?

ASN is a network identifier. ASN Owner is the operator. Enterprise is the actual assigned company.

How accurate is the Longitude / Latitude?

IP coordinates are for reference only. They are the center of the city or datacenter.

What does Proxycheck.io mean?

Your IP is recognized as a proxy/VPN, causing strict sites to block access.

Why detect Timezone and Language?

Key part of device fingerprinting. Mismatched timezone/language flags environment as spoofed.

🏷️ Basic Network & IP Profile

Hosting IP vs Residential IP?

Hosting IPs are data centers. Others are Residential. iobox uses micro-granular identification.

Why do Dual ISPs show as Hosting?

Dual ISP only means owner is ISP. iobox identifies its actual physical usage as a datacenter.

Is iobox's detection 100% accurate?

Overall accuracy is around 95%. Newly shifted IPs might have slight delays.

What is Native IP vs Broadcast IP?

Native IP matches registered country. Broadcast IPs are large blocks routed to different countries.

🛡️ Security & Risk Assessment

What is AbuseIPDB? Why high risk for Residential?

AbuseIPDB monitors malicious activities. A residential IP used for hacking will have a high score.

What is 'Sharing Status'?

Estimated user count. High numbers strongly indicate a public proxy/VPN. Hidden for CN.

What is IPQS and 'Bot' Traffic?

IPQS is an anti-fraud agency. Bot Traffic means automated script signatures, common in proxy pools.

🥷 Privacy & Leak Prevention

What are the harms of real leaks?

WebRTC completely exposes real IP. DNS Leak exposes browsing history to ISPs.

What is WebRTC Leak?

WebRTC fetches real IPs via UDP packets. If a proxy only handles TCP, UDP bypasses it instantly.

How to check and prevent WebRTC leaks?

Set media.peerconnection.enabled to false. Install uBlock Origin. Or use proxy TUN mode.

What is a DNS Leak?

If queries go to your ISP, browsing history is exposed. Causes include misconfiguration or IPv6 bypass.

How to fix a DNS Leak completely?

Enable TUN mode and fake-ip. Disable IPv6, and turn off Browser Secure DNS.

DoH vs DoT vs Regular DNS?

Regular: Plaintext. DoT: Encrypted obvious port. DoH: Disguised as HTTPS, highly secure.

🌐 IPv6 & Dual-Stack

What is IPv6 and Dual-Stack?

Many proxies miss IPv6 traffic, causing local IPv6 to leak. We test both to prevent stealth leaks.

Are IPv6 proxies good?

Cheap, but platforms often ban entire /64 subnets, risking collateral damage.
