A proxy server is a computer that sits between you and the internet. When you use a proxy, your request goes to the proxy first, and the proxy passes it on to the website using its own IP address instead of yours.
This simple change powers privacy, access and data work. This guide explains how proxy servers work, the main types, and why people use them.
How a proxy server works
When you connect through a proxy, the website sees the proxy IP, not your real one. The proxy forwards the reply back to you, so you get the page while your own address stays hidden.
This lets you appear to browse from another location, spread requests across many IPs, and add a layer between your device and the sites you visit.
Main types of proxy servers
Proxies come in a few main types, each suited to different jobs.
- Residential proxies use real home IP addresses and look like normal users
- Datacenter proxies are fast and cheap but easier for sites to spot
- ISP proxies mix the speed of datacenter with the trust of residential
- Mobile proxies use phone networks and are the hardest to block
Why people use proxy servers
Proxies solve real problems for individuals and businesses alike.
- Privacy by hiding your real IP address
- Access to region locked or restricted content, where lawful
- Managing many accounts without them being linked
- Web scraping and price monitoring at scale
- Ad verification and brand protection
Choosing the right proxy
Pick the proxy type that matches your task. Residential and mobile suit strict targets and account work, while datacenter suits fast, easier jobs. Always use proxies for lawful purposes and choose a trusted provider with clean IPs.
