This page shows public proxy servers with IP addresses detected in Slovakia. The list is often small, so the fastest way to use it is to test the freshest entries instead of spending time comparing too many columns.
If Slovakia has too few active options, use the main European proxy list to check other European countries.
Before testing a Slovakia proxy, read the protocol column carefully. An HTTP proxy must be added as HTTP, while SOCKS entries need SOCKS settings. The port is part of the setup, so copy it together with the IP address.
When only a few Slovak proxies are visible, Last Checked and Uptime should come before Speed. A recently checked entry with low uptime may still be worth testing, but an old entry with a better speed value can already be offline.
