What is a proxy server address and how does it work? or Can someone explain what is a proxy server ad

Proxies are like digital disguises—your traffic goes through another server first. The address is just the IP of that server.

They’re great for privacy (sometimes) and bypassing restrictions, but free ones? Meh. Slow and unreliable.

If you wanna test yours, use BrowserLeaks.com. For a decent proxy, check out GeoSurf or Storm Proxies.
