DNS leak test
Run a DNS leak test against your active connection. We probe multiple resolvers and report which servers your queries actually reached.
We compare the IP your HTTPS traffic exits from (as seen by our edge) against the IP a public anycast probe sees on the same family. A same-family mismatch usually means traffic is being routed outside the tunnel. This is a heuristic, not a forensic test.
Cloudflare’s trace endpoint didn’t respond — it’s sometimes blocked by ad-blockers or restrictive networks. The origin probe still ran.
For a forensic test we’d run our own resolvers — that ships in a future release.
What this test actually does.
The probes, the servers, the assumptions — exposed up front so you know what the result means.
We compare the exit IP our edge sees against the exit IP Cloudflare's anycast edge sees on the same family. A same-family mismatch usually means traffic is being routed outside the tunnel. This is a consistency check, not a forensic DNS probe — that requires our own authoritative resolver, which ships in a future release.

The full toolbox — same lab, same standards.
What is my IP address?
See your public IP, ISP, and approximate location. Detects IPv4 / IPv6 separately.
WebRTC leak test
Many browsers leak your real IP through WebRTC even when you're connected to a VPN. This tool surfaces the leak in real time.
VPN speed test
Measure your VPN's download throughput, upload, and latency against a clean baseline. Same rig we use to score providers.
Kill switch test
Verifies that your VPN's kill switch actually blocks traffic when the tunnel drops. We simulate a disconnect and report leaks.
VPN latency map
Compare round-trip latency to every server region for every VPN we test — picked the right one for your region.
