Proxy Checker Guide
Supported proxy formats
One proxy per line. Proxy must use public IP (does not accept domain names, internal IP 10.x, 192.168.x...), each line is maximum 300 characters long.
| Form | For example |
|---|---|
| IP:PORT | 103.1.2.3:8080 |
| IP:PORT:USER:PASS | 103.1.2.3:8080:user1:matkhau |
| [IPv6]:PORT | [2401:db8::10]:8080 |
| [IPv6]:PORT:USER:PASS | [2401:db8::10]:8080:user1:matkhau |
| Specify the connection type | socks5://103.1.2.3:1080 |
Has a prefix http://, https://, socks4://, socks4a://, socks5://, socks5h:// then just try it that way. If there is no prefix, try reviews HTTP, HTTPS (CONNECT), SOCKS5.
How to read the results
- Work The proxy can connect and go out to the Internet from the test server.
- Error Can't connect to the proxy (port closed, computer turned off) or can connect but can't go to the Internet (wrong user/password, blocked proxy).
- Cannot check The stream is in the wrong format, the internal IP, or the system is busy. It's not that the proxy is dead, you can check again.
Latency is the time of a successful attempt, including connecting to the proxy and loading the target page. IP comes out is the IP that other websites see when you use a proxy.
View VPSTTT proxy packagesFrequently Asked Questions
What does the tool check?
For each proxy, the server checks the connection to the Internet through that proxy and indicates whether the proxy is still active or not, the connection type that can be run (HTTP, HTTPS CONNECT, SOCKS5, SOCKS4), latency and IP of the proxy going out to the Internet.
Why does a proxy show as active but I still can't use it?
The tool checks proxies from VPSTTT's servers. If a proxy only allows certain IPs to connect, your own IP must also be allowed on the proxy before you can use it.
What's the difference between "Unable to test" and "Error"?
"Error" means the server has been checked and the proxy is unavailable. "Unable to check" is a malformed line, using a domain name instead of an IP, an internal IP, or the checking system is busy; This is not a dead proxy, you can click check again.
How many proxies can be checked at once?
Paste as many lines as you like. The tool splits the list into small batches and checks them in parallel, showing each result as soon as it is ready. An unresponsive proxy takes about 8 seconds before it is reported as dead, so lists with many dead proxies take longer.
Is my proxy information saved?
The proxy list is only sent for testing, the website does not save and does not log the proxy list or users/passwords. Results are only visible in your browser; The password in the results table is masked.
