Rotating Proxies Explained: How They Work, Types, and When to Use Them

By using rotating proxies, you can connect to even the most restrictive websites or web APIs without worrying about IP bans. In this article, we’ll explain in detail what rotating proxies are, their common use cases, how to choose the right provider, and more. Let’s start with the basics of rotating proxies and how they work. 

What Is a Rotating Proxy?

A rotating proxy is the type of proxy that changes the IP address of your connection requests after a predetermined time interval. The IP addresses assigned to your connection are extracted from an IP pool of your proxy provider. IP rotation is what makes these proxies great for tasks like web data scraping from websites that normally ban IPs extracting a lot of data in a short time interval.   

How Rotating Proxies Work in Practice

Rotating proxies work by routing your traffic through a pool of IPs offered by your provider. This means that every request you make to the proxy is assigned a different IP address or you may choose a time interval after which the IP of your connection is changed. 

Regardless of what your case is, the goal is to ensure different IPs are used to connect to the same target website or API after a given time interval. This can be pretty useful when handling sensitive tasks like data scraping. 

Common Business Use Cases

Some of the common use cases of rotating proxies include: 

• Web Scraping: Rotating proxies are commonly used for scraping large amounts of data from websites or APIs without triggering anti-bot systems. Since the IP address of your connection keeps changing, it becomes harder for these websites or web APIs to block your data scraping connection. 
• SEO Monitoring: Datacenter and residential proxies can also be used to track keyword rankings and competitor data from multiple regions without triggering Captchas. They can also be used for scraping data from the SERP. Using different IPs makes your connections seem like they are coming from different users.
• Ad Verification: By using datacenter or residential rotating proxies, businesses can ensure their ads are displayed correctly across different locations and platforms.
• Market Research: Using rotating proxies allows businesses to access pricing, reviews, and product data from various sites anonymously. Scraping data from these sites also becomes seamless when using proxies.
• Cybersecurity Testing: Cybersecurity professionals and website admins can use rotating proxies to simulate different IP sources to test firewall rules and access controls.
• App and website testing: Developers can use rotating proxies (residential or mobile) to simulate how their websites or web APIs perform for users in different regions. Rotating proxies give you access to numerous IPs in different regions, making website or web API testing a lot easier. 

Types of Rotating Proxies

Before you start using rotating proxies, you must choose the appropriate type depending on the task you intend to accomplish. Here is how the different types of rotating differ. 

Rotating Residential Proxies

Rotating proxies give you access to IP addresses that are assigned by local internet service providers to real residential devices such as computers, routers, and more. When you connect with a rotating residential proxy, your traffic is routed through the residential IPs from one of these devices. Each time the proxy rotates, your connection will appear like it is coming from a different home device, making it less likely to encounter IP bans. 

Residential proxy services usually allow providers to offer millions of IPs since it is much easier to get home device IPs than deploying and managing millions of servers. These rotating proxies also make it possible to have IPs in literally every country in the world. For context, ProxyWing offers millions of IPs in more than 190 countries around the world. Some of the popular use cases for rotating residential proxies include web scraping, ad verification, and price monitoring. 

Rotating Datacenter Proxies

Rotating datacenter proxies allow you to use IP addresses of servers hosted on different datacenters around the world. Since these IPs are from proxy servers in data centers, they usually offer the fastest connections. Providers find it much easier to optimize the performance and reliability of these IPs because they have more control over them. That’s why they are also usually cheaper

The only downside of using IPs from datacenter proxy servers is that they are easier to detect. This increases the chances of facing IP bans, especially when using these proxies to access strict websites and APIs. However, performance and cost benefits of these proxies can sometimes make them worth it. Some of the popular use cases for using rotating proxies in datacenters include bulk data scraping, market research, and SEO tracking. Scraping may not be as effective since these proxies are easier to detect than most other types.

Rotating Mobile Proxies

With rotating mobile proxies, your connection is routed through IP addresses of devices connected to mobile networks (3G, 4G, or 5G). The mobile IPs of these proxies are also usually ISP-assigned and shared among real users, making them extremely difficult to blacklist. To the websites or APIs being accessed, these proxies make your connection seem like it is coming from a mobile device. 

Mobile proxy solutions are perfect for social media management, ad verification, and simulation of mobile app performance. They can also be used for small scale data scraping. Most websites and APIs also trust mobile traffic, making them the best choice when trying to access sites with sensitive proxy IP filters. Since the IPs of these proxies are constantly rotated, they also make your connection more anonymous. The only downside is that these proxies are usually more expensive than datacenter proxies. 

Static vs Rotating proxy

These are two other proxy categories that you need to know about. While rotating and static proxies all serve the same purpose, they are significantly different in their IP addressing process, performance, and scalability. Let’s explore the “static vs rotating proxies” differences in detail to help you choose the best proxy type. 

Key Differences in IP Rotations

With dedicated static proxy services, all the requests you make maintain the same IP address. When using these proxies, your IP address will remain the same for the entire session unless you manually change your proxy settings to use a different IP address. Having stable and dedicated IPs can make these proxies useful for tasks that require long-term logins and sessions that require stable connections.

On the other hand, proxies with rotating IPs will dynamically change your IP address for every request or after a given time interval. Even though these proxies may not be suitable for certain tasks, constant IP rotating is useful for a number of use cases. Such use cases may include web scraping or doing automation tasks on strict websites and APIs. 

Performance and Security Comparison

When it comes to performance, static residential or datacenter proxies usually come out on top since they don’t have to constantly change IPs for every request. This makes static residential or datacenter proxies great for tasks like streaming and online gaming where great performance and maintaining stable connection is crucial. 

Rotating proxies meaning dynamic IP proxies on the hand, offer the best security and anonymity since they constantly change your IP. This makes using these proxies the best choice when you need maximum privacy and minimizing the possibility of websites and APIs tracking your browsing activities. 

Pricing and Scalability

When it comes to pricing, static proxies are usually more affordable since they don’t need your proxy provider to source to many IPs. However, these proxies could become the limiting factor, especially when handling large web scraping tasks.

Rotating proxies come out on top when it comes to scalability. With these proxies, you can trigger thousands of requests going to the same website and APIs simultaneously, which is crucial for tasks like data scraping. However, rotating proxies are also usually more expensive. 

How to Use Rotating Proxies

Using rotating proxies is straightforward even for less tech users. However, you need to first understand how to configure them. Let’s explore the key setup steps involved: 

• Get proxy details: Obtain the proxy host, proxy port, and login credential (if needed) from  your proxy provider.
• Choose rotation settings: Proxy providers like ProxyWing allow rotation per request, per session, or after a specific time interval. 
• Integrate with your application: After getting the proxy details, you will need to configure your software, script, or device to route all traffic through the proxy.
• Test the connection: You can do a simple request to check if your public IP changes after each request or interval.

cURL Configuration Example

You can quickly test a rotating proxy server using cURL in your terminal using the command below: 

curl -x http://username:password@proxyserver:port https://api.ipify.org?format=json

You can run several of these commands, your IP should change every time you run it. 

Python Configuration Example

You can also use Python’s requests library to easily connect to rotating proxies by updating the proxies parameter. Below is the simple script. 

import requests
proxies = {
    "http": "http://username:password@proxyserver:port",
    "https": "http://username:password@proxyserver:port"
}
for i in range(5):
    response = requests.get("https://api.ipify.org?format=json", proxies=proxies)
    print(response.json())

If your rotating proxy server provider supports IP rotation, a different proxy IP will be printed every time you run the script above. 

Java Configuration Example

Here is how you can configure connecting to a rotating proxy server using Java. 

import java.net.*;
import java.io.*;
public class RotatingProxyExample {
    public static void main(String[] args) throws Exception {
        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxyserver", port));
        URL url = new URL("https://api.ipify.org?format=json");
        HttpURLConnection connection = (HttpURLConnection) url.openConnection(proxy);
        String encodedAuth = Base64.getEncoder()
            .encodeToString(("username:password").getBytes());
        connection.setRequestProperty("Proxy-Authorization", "Basic " + encodedAuth);
        BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine()) != null) {
            System.out.println(inputLine);
        }
        in.close();
    }
}

Pros and Cons of Rotating Proxies

Like any other proxy offering, rotating proxies have advantages and disadvantages. Let’s explore them:

Alternatives to Rotating Proxies

Even though rotating proxy services offer several benefits, there are some use cases they don’t excel in. For such needs, you may want to consider other proxy alternatives. Let’s explore some of these alternatives.

Static Proxies

Unlike rotating proxies, static proxies provide a single unchanged IP address for the entire session. This can be crucial when connection stability is needed to maintain a seamless browsing experience. You may also choose static proxies over rotating proxies because they are cheaper. 

Proxy Rotators and APIs

Instead of having to manage multiple proxies, you can use proxy rotators or rotation APIs. These proxy tools automate the process of switching your connection between multiple proxy servers. This makes them a great choice for developers carrying our large data scraping and automation tasks. 

Choosing the Right Proxy Provider

There are several proxy providers offering rotating proxy services, but the one you choose will have a huge impact on your overall experience. Before choosing a proxy provider, here a few key factors that you must consider:

• IP Pools Size: The proxy provider must offer a relatively large pool of proxy IPs for better rotation variety and lower chances of detection. 
• Speed and Uptime: Ensure your proxy provider has a good reputation of providing fast proxy speeds and uptime of at least 99%.
• Rotation Control: Your proxy provider should give you more flexibility on the frequency of IP rotation.
• Geolocation Options: You need proxy providers offering proxy IPs in almost every country. 
• Customer Support and API Access: Your proxy provider must offer reliable support. It should ideally be available 24/7 in case you need help. 

Conclusion

Rotating proxies are an excellent choice, especially for tasks that require a high level of anonymity or when you need to make multiple requests to the same websites simultaneously without detection. Reliable providers for proxies offer access to IPs from several countries, allowing you to cycle through them and bypass most proxy detection systems.
