// PROXY.check(list)

PROXY CHECKER

Paste up to 15 proxies to see whether they work, which country and ISP they exit through, their latency and whether websites can tell it is a proxy.

One proxy per line, up to 15. We connect through each proxy to our IP check service and show the exit IP. We do not store your proxies.

Country and ISP: IP Geolocation by DB-IP

How the check works

Our server connects to each proxy and opens our service page through it. That page sees which IP the request came from and which headers the proxy added on the way. From this we show the exit IP, country, ISP, latency and anonymity level.

You do not have to specify the protocol: the checker detects HTTP or SOCKS5 by itself. Supported formats are host:port, host:port:user:password and user:password@host:port.

What the anonymity level means

  • Elite. Websites see no signs of a proxy. This is what you need for account work.
  • Anonymous. Your IP is hidden, but headers like Via or X-Forwarded-For show that the request came through a proxy.
  • Transparent. The proxy passes the IP of whoever connected to it. Not suitable for anonymous work.

The level is checked over plain HTTP. Over HTTPS a proxy cannot add headers, so HTTPS websites only see the proxy exit IP anyway.

FAQ

Do you store my proxies?+

No. The list lives in memory only while the check runs. The log records just the number of checks, without addresses, usernames or passwords.

How much traffic does a check use?+

A few kilobytes per proxy: two short requests to our IP check service.

Why does a rotating proxy show a new IP every time?+

That is expected: rotation changes the address on every new connection. A sticky proxy keeps showing the same IP while the session lives.

Why is the latency around a second or more?+

That is normal for mobile and residential proxies. The latency includes picking a device and a secure connection over the mobile network.

The proxy works, but a website still blocks me. Why?+

The checker shows that the proxy is alive, where it exits and how anonymous it is. Whether a specific platform has blocked the address cannot be seen from here. Most often the cause is browser settings: time zone, language or a WebRTC leak.

Can I check proxies bought elsewhere?+

Yes, the checker works with any HTTP and SOCKS5 proxies.
