What Is My IP &
IPv6 Leak Test
Inspect your public IPv4 and IPv6 endpoints, audit dual-stack VPN tunnel security, detect WebRTC IP leaks, and verify ISP origin data in real time.
Dual-Stack Connection Probe
Queries separate IPv4, IPv6, and WebRTC STUN endpoints to detect tunnel leaks.

How Dual-Stack Leaks Occur
Modern operating systems prefer IPv6 by default whenever available. Incomplete proxy configurations allow direct identity exposure.
IPv4 & IPv6 Coexistence
Consumer ISPs assign both a 32-bit IPv4 address and a 128-bit IPv6 subnet. Browsers prefer connecting over IPv6 when AAAA DNS records exist.
Unrouted IPv6 Leaks
Legacy VPN clients only create routing tables for IPv4. Inbound IPv6 traffic bypasses the proxy adapter, exposing your genuine residential identity.
WebRTC Dual Discovery
WebRTC peer connections send STUN queries over all available network interfaces, collecting both IPv4 and IPv6 network candidates directly.
Carrier Correlation
Ad networks match proxy IPv4 datacenter ASNs against leaked residential IPv6 blocks to unmask multi-account marketing operations.
Ad platforms check IPv6 residential roots.
Shield both protocols with Cloaker.net.
Many affiliate marketers run IPv4 proxies, unaware that their mobile carrier or ISP simultaneously broadcasts a native IPv6 address. Automated review systems (Meta, Google Ads, TikTok) use these IPv6 leaks to map multi-account networks. Cloaker.net runs edge filtering across both IPv4 and IPv6 simultaneously in under 15ms.
Frequently asked questions
Common technical questions about IPv6 leak prevention, VPN testing, and cloaking defense.
An IPv6 leak occurs when a VPN or proxy tunnel only secures legacy IPv4 traffic while leaving native IPv6 traffic unencrypted. Websites can query your real IPv6 address directly, bypassing your proxy protection.
Ad networks (Meta, Google Ads, TikTok) actively cross-reference IPv4 proxy endpoints with residential IPv6 footprints. If your genuine residential IPv6 leaks past your proxy, ad platforms link the session to your real identity and trigger account bans.
If your ISP or current network does not support IPv6, or if your VPN successfully blocks or disables IPv6 traffic, no IPv6 address will be detected. This confirms zero risk of an IPv6 tunnel leak.
Cloaker.net edge middleware filters both IPv4 and IPv6 streams simultaneously, applying automated bot identification, ASN verification, and sub-15ms conditional redirects across all network protocols.
