What type of proxies can be checked?

Proxy checker allows checking free and paid proxies of IPv4, IPv6 protocols.

In what format should a proxy be added to a proxy checker?

For free proxies - the IP:PORT format and each address on a new line; for paid proxies - the IP:PORT: USER:PASS format is provided by your seller, each address is on a new line.

What filters do on the right of the proxy checker?

If you want to check a large number of addresses and your software/service supports only one of the protocols - you can turn off the unnecessary and the final list will be compiled with the deduction of the disabled parameter, as well as a possibility to immediately remove the display of non-working IPs.

Does the proxy checker validate both SOCKS and HTTP|S?

Yes, our proxy validity checker checks all existing protocols.

Can I upload a list of IPs for verification?

To upload a list of addresses from a file, use the recommended formats depending on the type of proxy and, if available, the links “download from .txt or .csv”

Does the validator check addresses both paid and free?

Yes, our service supports checking both paid and free proxies. Pay attention to the necessary formats for accurate verification. For example, if the proxy is paid and you insert IP:PORT into the checker, the IP will be displayed as inoperative, because the system could not check it correctly.

What if after checking the proxy turned out to be inoperative?

There are only three possible recommendations for this case. Check the correct input format corresponding to your type of proxy, do not use free proxies - the lifetime of such a product is extremely short, check the authorization data in the case of private IPs from your provider.
