What Are Proxies and How Do They Work

A proxy routes your internet traffic through another IP so sites see that address instead of yours. Learn how proxies work, the main types, and when to use one.

What Is a Proxy

A proxy is a server that sits between you and the websites you visit. Instead of connecting directly, your request goes to the proxy, the proxy forwards it using its own IP address, and the response comes back through the proxy to you. The website sees the proxy IP, not yours. That simple redirection is the basis for privacy, geo targeting, and large scale data collection.

How a proxy works, step by step

  1. You send a request to the proxy instead of the destination.
  2. The proxy forwards it from its IP address.
  3. The site responds to the proxy IP.
  4. The proxy passes the response back to you.

Because the visible IP is the proxy, you can control what location and what kind of address the site sees.

The main types of proxy

  • Residential: real IPs from home internet connections. High trust, hard to block, ideal for protected sites.
  • ISP: residential IPs hosted in a datacenter. Static, fast, and trusted.
  • Mobile: IPs from 4G and 5G carriers. Highest trust because many real users share them.
  • Datacenter: fast and cheap server IPs, easy to detect on defended sites.

Rotating vs sticky

A rotating proxy gives you a new IP on each request, which is great for spreading large crawls. A sticky proxy keeps one IP for a set time, which suits logins and checkouts.

What people use proxies for

  • Web scraping and price monitoring across regions
  • Ad verification and SEO rank tracking
  • Managing multiple accounts
  • Accessing region specific content

ShiftProxies offers residential, ISP and mobile proxies in 195 plus countries so you can match the IP type to the task at dashboard.shiftproxies.com.

Are proxies legal

Using proxies is legal in most places and common for legitimate business work. What matters is how you use them: respect the terms of the sites you visit, follow local laws, and avoid collecting personal data you are not allowed to process.

Summary

A proxy swaps your visible IP for another, letting you appear as a different user or location. Pick residential for trust and coverage, ISP for static speed, mobile for the strictest targets, and datacenter for cheap speed on easy sites.

Frequently asked questions

What does a proxy actually do?+

It forwards your traffic through another IP address, so the destination site sees the proxy IP instead of your real one.

Which proxy type should a beginner use?+

Residential proxies are the best general starting point: high trust, broad coverage, and hard to block on most sites.

Do proxies make me anonymous?+

They hide your real IP from the destination site, but true privacy also depends on using HTTPS and not leaking identity through logins or cookies.

Are proxies and VPNs the same?+

Both reroute traffic, but a VPN encrypts all device traffic through one server, while proxies are per app or per request and offer many IPs to choose from.
