Proxy checker

The checker connects to each proxy and requests the external IP through it. If it responds, we show the address, country, city and response time.

If not, we show why: a wrong password, a closed port, no reply within 10 seconds, or the proxy accepts neither HTTP nor SOCKS5.

Most often it's a typo in the username or password, then the proxy replies with code 407. The second cause is a wrong port. No need to pick a protocol, both are checked.

Residential and mobile proxies with narrow geo may have no free node in the chosen city or ZIP code. Try again in a minute or widen the geo to the country.

The time of a full request from our server. From your computer it will differ, so compare proxies with each other.

We don't store proxies, usernames or passwords, and don't write them to logs. A check uses about 150 KB of traffic per proxy. If you'd rather not share credentials, change the format in the formatter: it works right in your browser.
