What Is a Proxy Server?

A proxy server is a computer that sits between your device and the internet. When you send a request — say, loading a webpage — the request goes to the proxy first. The proxy then forwards it to the destination server on your behalf, receives the response, and sends it back to you.

To the website you are visiting, the connection appears to come from the proxy, not from you. Your real IP address stays hidden behind the proxy's address.

Why Use a Proxy?

People use proxies for several practical reasons:

• Privacy — Your real IP address and location are not exposed to the sites you visit.
• Access — Proxies let you reach content that may be geo-blocked in your region.
• Security — Organizations route traffic through proxies to filter malicious websites and monitor usage.
• Performance — Caching proxies store copies of frequently requested content, reducing load times.

How It Works in Practice

1. You configure your browser or application to route traffic through the proxy.
2. Your request is sent to the proxy server.
3. The proxy forwards the request to the target website.
4. The website responds to the proxy.
5. The proxy relays the response back to you.

Different proxy types offer different levels of anonymity and functionality. Whether you need a simple HTTP proxy or a full-featured SOCKS5 proxy, ipproxy.site has you covered — check out our proxy plans or download the client to get started.
