What Is a Rotating Proxy?

A rotating proxy is a proxy service that automatically assigns a different IP address from a pool for each request — or at a defined interval. Unlike a static proxy, where you always connect through the same IP, a rotating proxy ensures that your traffic appears to come from many different users across different networks and locations.

Think of it as having access to thousands (or millions) of different identities on the internet. Each time you make a request, you appear as a completely different visitor. This is the foundational mechanism behind large-scale web scraping, SERP tracking, and data collection operations.

How Rotating Proxies Work

The Gateway Model

Modern rotating proxy services like ProxyHat use a gateway architecture. You connect to a single endpoint — gate.proxyhat.com on port 8080 (HTTP) or 1080 (SOCKS5) — and the gateway handles all the complexity behind the scenes.

Here's what happens on every request:

1. Your application sends a request to the ProxyHat gateway
2. The gateway authenticates your credentials
3. The routing engine selects an IP from the pool based on your configuration (random, geo-targeted, etc.)
4. Your request is forwarded through the selected IP to the target website
5. The target responds, and the gateway relays the response back to you
6. On the next request, a different IP is selected

This entire process is transparent — your code never needs to manage individual proxy addresses. For a deeper technical explanation, see our article on how IP rotation works.

Back-Connect Architecture

The gateway model is sometimes called "back-connect" because the gateway connects backward into the proxy pool on your behalf. You maintain a single connection to the gateway, while the gateway maintains connections to the pool. This is fundamentally different from the old approach of distributing a list of proxy IPs to your application.

# Same endpoint, different IP each time
curl -x http://USERNAME:PASSWORD@gate.proxyhat.com:8080 https://httpbin.org/ip
# → {"origin": "185.23.xx.xx"}
curl -x http://USERNAME:PASSWORD@gate.proxyhat.com:8080 https://httpbin.org/ip
# → {"origin": "91.107.xx.xx"}
curl -x http://USERNAME:PASSWORD@gate.proxyhat.com:8080 https://httpbin.org/ip
# → {"origin": "45.89.xx.xx"}

Rotation Strategies

Every-Request Rotation

The most common strategy: each HTTP request receives a fresh IP from the pool. This offers maximum anonymity and is ideal for scraping independent pages where no session continuity is needed.

Sticky Sessions (Timed Rotation)

Some tasks require sending multiple requests through the same IP — for example, navigating a multi-page workflow or maintaining a login session. Sticky sessions hold the same IP for a configurable period (typically 1 to 30 minutes), after which a new IP is assigned.

Geo-Constrained Rotation

You can rotate through IPs within a specific geographic area. This combines the anonymity benefits of rotation with the location precision of geo-targeting. Essential for localized SERP tracking and regional price monitoring.

Types of Rotating Proxies

Rotating Residential Proxies

Residential proxies are IP addresses assigned to real households by ISPs. Rotating residential proxies cycle through millions of these IPs, providing the highest trust level because each address looks like a real consumer. This is the gold standard for scraping sites with strong anti-bot protection.

Rotating Datacenter Proxies

Datacenter proxies are hosted on server infrastructure and are faster but easier to detect. Rotating datacenter proxies are best for targets with minimal anti-bot defenses where speed is the priority.

Rotating Mobile Proxies

Mobile proxies use IP addresses from cellular carriers. Because mobile IPs are shared among many users via CGNAT, they have extremely high trust scores. Rotating mobile proxies are the most expensive option but offer the best success rates against the most aggressive anti-bot systems.

When to Use Rotating Proxies

Web Scraping at Scale

Collecting data from thousands or millions of pages requires distributing requests across many IPs to avoid rate limits and blocks. Rotating proxies are the standard tool for large-scale scraping operations.

SERP Scraping

Search engines aggressively rate-limit and CAPTCHA scrapers. Rotating proxies, especially geo-targeted residential ones, let you collect SERP data at scale without triggering detection.

Price Monitoring

E-commerce data collection benefits from rotating proxies because retailers actively detect and serve different prices to suspected bots. Rotation ensures each price check appears to come from a different shopper.

Market Research

Gathering competitive intelligence from multiple sources requires broad, distributed access. Rotating proxies let you access thousands of websites without any single site seeing concentrated traffic from your operation.

Implementing Rotating Proxies with ProxyHat

Python Example

import requests
PROXY = "http://USERNAME:PASSWORD@gate.proxyhat.com:8080"
urls = [
    "https://httpbin.org/ip",
    "https://httpbin.org/headers",
    "https://httpbin.org/user-agent",
]
for url in urls:
    resp = requests.get(
        url,
        proxies={"http": PROXY, "https": PROXY},
        timeout=15,
    )
    print(f"{url}: {resp.status_code}")

Node.js Example

import axios from "axios";
import { HttpsProxyAgent } from "https-proxy-agent";
const agent = new HttpsProxyAgent("http://USERNAME:PASSWORD@gate.proxyhat.com:8080");
const urls = [
  "https://httpbin.org/ip",
  "https://httpbin.org/headers",
  "https://httpbin.org/user-agent",
];
for (const url of urls) {
  const { data, status } = await axios.get(url, { httpsAgent: agent });
  console.log(`${url}: ${status}`);
}

Go Example

package main
import (
    "fmt"
    "net/http"
    "net/url"
)
func main() {
    proxyURL, _ := url.Parse("http://USERNAME:PASSWORD@gate.proxyhat.com:8080")
    client := &http.Client{
        Transport: &http.Transport{Proxy: http.ProxyURL(proxyURL)},
    }
    urls := []string{
        "https://httpbin.org/ip",
        "https://httpbin.org/headers",
    }
    for _, u := range urls {
        resp, err := client.Get(u)
        if err != nil {
            fmt.Printf("Error: %v\n", err)
            continue
        }
        fmt.Printf("%s: %d\n", u, resp.StatusCode)
        resp.Body.Close()
    }
}

For production use, the Python SDK, Node SDK, and Go SDK provide built-in retry logic, error handling, and request queuing.

What Makes a Good Rotating Proxy Service

• Large IP pool: More IPs mean less reuse and lower detection risk. Look for pools in the millions for residential proxies
• Geographic diversity: IPs across many countries, cities, and ASNs ensure you can target any market
• Pool health monitoring: The provider should actively remove banned or flagged IPs from the pool
• Flexible rotation: Support for both per-request and sticky-session rotation modes
• Dual protocol support: HTTP and SOCKS5 access for maximum compatibility
• Clear pricing: Transparent per-GB pricing with no hidden fees — see ProxyHat pricing

Key takeaway: Rotating proxies are the essential tool for any operation that needs to send many requests without being identified as a single actor. By automatically cycling through diverse IPs, they let you collect data at scale while maintaining anonymity and avoiding blocks.

Frequently Asked Questions

How many IPs do rotating proxy pools typically have?

Quality residential rotating proxy pools contain millions of IPs. Datacenter pools are smaller (tens of thousands to hundreds of thousands) but offer faster speeds. The larger the pool, the lower the chance of IP reuse.

Can I maintain sessions with rotating proxies?

Yes, through sticky sessions. You can keep the same IP for a defined period (usually 1-30 minutes) to maintain login states, shopping carts, or multi-page workflows.

Are rotating proxies legal?

Proxies themselves are legal technology. The legality depends on what you do with them. Always respect target websites' terms of service and applicable data protection regulations.

What's the difference between a rotating proxy and a VPN?

A VPN assigns you a single IP for the duration of your connection and encrypts all traffic. A rotating proxy changes your IP on every request (or interval) and is designed for programmatic use, not general browsing. Rotating proxies are purpose-built for data collection.
