Claude Proxy Network Checker (Exit IP & Timezone)
Detect your real exit IP and region, cross-check it against system timezone, language and WebRTC leaks to find proxy exposure points and reduce Claude ban risk
TL;DR Summary & Citation: [Claude Proxy Network Checker (Exit IP & Timezone)] is used to Detect your real exit IP and region, cross-check it against system timezone, language and WebRTC leaks to find proxy exposure points and reduce Claude ban risk. This feature sends the parameters needed for the query to the PocketKit API or the third-party service identified on the page. Do not submit unrelated sensitive data.
How exit-IP and proxy consistency detection works
The tool reads the exit IP, region and ASN that this site Cloudflare edge sees (request.cf), reads system timezone and language via browser APIs, gathers ICE candidates via WebRTC, then cross-checks them, focusing on whether the system timezone or language contradict the exit-IP region. Exit data comes from this site own Cloudflare, no third party.
Usage Guidelines & Tips
- Use this tool on the deployed live site; local or preview cannot read the exit IP.
- If a timezone leak is flagged, first change the OS timezone to a non-China zone consistent with the exit IP.
Frequently Asked Questions
1. Why is the exit IP unavailable locally or in preview?
The exit IP and region come from this site own Cloudflare edge (request.cf) and only work on the deployed live site; local dev shows a notice. The data never passes through a third party and is not stored.
2. Why is a timezone that disagrees with the exit IP risky?
Even behind a proxy IP, the system timezone can betray your real location, e.g. an IP in the US but a system timezone of Asia/Shanghai, the most common proxy leak. Ideally exit region, system timezone and browser language all align.
3. How does WebRTC leak real IP addresses bypassing HTTP proxies?
WebRTC initiates UDP STUN probe packets to discover candidates for peer-to-peer media streams. Because standard browser proxy extensions only handle TCP/HTTP(S) traffic, UDP STUN queries bypass the proxy and expose your underlying WAN/LAN IP directly to client-side scripts.
4. What is the difference between Hosting ASN and Residential IP for Claude access?
Every IP belongs to an Autonomous System Number (ASN). IPs owned by cloud hosts (AWS, GCP, OVH) are tagged as Datacenter/Hosting, which face aggressive fraud scoring from Claude security. ISP-allocated residential addresses resemble real consumer hardware and trigger fewer verification blocks.
5. How can I resolve and prevent DNS leaks?
When your proxy client is not operating in full TUN/TAP virtual network adapter mode, DNS lookups query your local ISP DNS servers in cleartext. Configure Fake-IP routing or DNS-over-HTTPS (DoH) inside your client so all DNS resolution resolves on the remote proxy node.
