Proxy Checker — Test a Proxy and See Its Exit IP

Paste an HTTP or HTTPS proxy — host, port and optional username and password — and this checker connects through it to a fixed IP-echo endpoint to confirm it works. You get a clear alive or unreachable verdict, the round-trip latency in milliseconds, and the exit IP the proxy routes through, so you can verify a proxy before wiring it into a scraper, a test suite or a geo-restricted workflow.

Enter the proxy hostname or public IP. It must be publicly reachable — private, loopback and internal addresses are rejected.

Only needed for proxies that require a username and password. Credentials are used for this one check and never stored.

No check yet

Enter a proxy host and port, then run the check to see if it is alive and what exit IP it uses.

How to use

  1. Enter the proxy host or public IP and its port.
  2. Choose HTTP or HTTPS, and add a username and password if the proxy needs them.
  3. Click “Check proxy” to connect through it to a safe, fixed IP-echo endpoint.
  4. Read the alive verdict, latency and exit IP, then copy the IP or a full summary.

Features

  • Clear alive or unreachable verdict, with the reason shown when a proxy fails
  • Round-trip latency measured in milliseconds
  • Reveals the exit IP so you can confirm traffic is genuinely being forwarded
  • Supports HTTP and HTTPS proxies, with optional username and password
  • Private, loopback and internal addresses are blocked as a built-in safeguard
  • One-click copy of the exit IP or a full text summary of the result

Frequently asked questions

What does the proxy checker actually test?
It routes a single request through your proxy to a fixed, public IP-echo endpoint and reports three things: whether the proxy is reachable, how long the round trip took in milliseconds, and the exit IP the request came from. It does not scan the proxy or fetch any page you choose.
What does the exit IP tell me?
The exit IP is the address the destination sees. If it differs from your own network’s IP, traffic is really being forwarded through the proxy. If it matches, the proxy is transparent and is not masking the origin.
Can I check a proxy on my local network or an internal IP?
No. Hosts that resolve to private, loopback, link-local or other reserved addresses are rejected. This is a deliberate safeguard so the tool cannot be used to probe internal services by naming them as a proxy.
Does it grade anonymity as transparent, anonymous or elite?
No. Reliable anonymity grading needs header-level inspection that varies by endpoint, so this tool sticks to what it can measure accurately: reachability, latency and the exit IP, plus whether that IP differs from your origin.
Is it OK to check any proxy I want?
Use it for proxies you own or are authorised to test — for example QA, geo-testing or checking a provider you pay for. Probing proxies or networks you do not control is not the intended use.
