Exit and Split Routing Test
Different websites can use different exits. This test puts the public IP each one sees side by side.

How the exit and split routing test works
-
Record the baseline
IPLense and public echo services return your current IPv4 and IPv6 exits as the starting point.
-
Ask websites and Mainland China sites
Each website’s
/cdn-cgi/tracereturns the exit IP, country, and Cloudflare data center it sees; the Mainland China sites return the address a server in mainland China sees. -
Compare IPv4 and IPv6 separately
When one family has several exits, they are labeled Exit A, B by how many sites see them. This split appears when a VPN, proxy, or routing rule handles only part of the traffic.
Reading the result
- Exit AThe exit seen by the most sites.
- Exit BAnother exit, seen by only some sites or echo services.
- Supported regionChatGPT or Claude officially supports this country or region.
- Not a supported regionThe exit’s location is not on the official supported list.
Frequently asked questions
What does traffic splitting mean?
Traffic splitting means requests from the same device leave through different exits for different destinations. It can be caused by an intentional routing rule, or by a VPN that does not handle certain domains, applications, or address families. An unexpected split can show a destination an IP, network owner, or location that differs from the one you intended.
Why are IPv4 and IPv6 together not considered split routing?
They are the two normal public address families of a dual-stack network. The test compares exits only within the same family, so one IPv4 and one IPv6 are not treated as a mismatch.
What does a difference within IPv4 or within IPv6 mean?
It means different sites may be using different exits. Common causes include VPN or proxy split routing, domain-based routing rules, or separate network interfaces handling different paths.
What can I do with the addresses found?
Every successful address can be checked for its network owner and location, helping distinguish a VPN exit, proxy route, or original network.
