When it comes to choosing a proxy service for web scraping, automation, or other tasks requiring an IP address change, one of the key decisions is whether to use static or rotating proxies. Both offer advantages and disadvantages depending on your use case, so let‘s dive into the key differences and when each type is ideal.

What Are Static Proxies?
Static proxies are IP addresses that remain fixed and do not change. When you use a static proxy, your requests will always originate from the same IP, even if your own IP is dynamic.
Static proxies are typically datacenter or ISP proxies hosted on servers with dedicated IP addresses. Since the servers are persistently online, they can assign static IP addresses to individual users or applications. While residential and mobile proxies can technically be static if hosted on proxy farms, their IP addresses tend to rotate frequently anyway due to the nature of consumer ISPs.
With static proxies, you directly receive a list of IP addresses to use, such as:
- Proxy 1: 123.456.789.10:1000
- Proxy 2: 234.567.891.112:1000
- Proxy 3: 345.678.910.11:1000
You then connect through each proxy individually for as long as needed.
What Are Rotating Proxies?
Rotating proxies automatically cycle your IP address through a pool of proxies randomly or at timed intervals. For example, you may rotate to a new IP every 1 minute, 10 minutes, 30 minutes, or after a set number of requests.
With rotating proxies, you do not directly access the underlying IP addresses. Instead, you connect through a gateway or load balancer that transparently assigns you proxies from the pool based on your rotation settings. This allows you to make requests from thousands of IP addresses without having to manage them individually.
While any proxy can be configured to rotate, residential rotating proxies are the most common type. This is because residential ISP customers tend to have dynamic IP addresses anyway, so the proxies naturally rotate IPs frequently.
Comparing Static and Rotating Proxies
Let‘s look at some key differences between static and rotating proxies:
| Feature | Static Proxies | Rotating Proxies |
|---|---|---|
| IP Rotation | No rotation – uses the same IP continuously | Automatically rotates IP addresses |
| Exclusivity | Can be shared or dedicated to you | Always shared pools |
| Performance | Fast, dedicated bandwidth on servers | Varies – datacenter good, residential inconsistent |
| Pricing | IP-based – pay per IP address | Traffic or port-based – pay for data used |
| Maintenance | Higher – manage individual IPs | Lower – simply rotate away issues |
Rotation
The core difference is that static proxies always use the same IP while rotating proxies cycle through many IPs automatically. This makes rotating proxies ideal for scenarios where you need to constantly vary your IP.
Exclusivity
Static proxies can be dedicated to your sole use or shared with other users. Rotating proxies, on the other hand, provide access to a pool shared by multiple customers.
Performance
Static proxies hosted on dedicated servers offer very fast speeds and bandwidth. Rotating datacenter proxies also typically have excellent throughput. However, residential rotating proxies have inconsistent performance since they rely on uncontrolled home internet connections.
Pricing
Static proxies are priced per IP address, while rotating proxies charge for bandwidth or number of ports. This tends to make static proxies more cost effective for long sessions but less efficient for tasks involving many IP switches.
Maintenance
With static proxies, you have to directly manage and potentially replace any IPs that are misbehaving or blocked. Rotating proxies make this easy by providing a fresh IP on demand.
When to Use Static vs Rotating Proxies
Use Cases for Static Proxies
- Long sessions such as social media or email account management
- Accessing geo-restricted content from a specific location
- Cost savings for low bandwidth tasks
- Selecting specific IPs based on features like ISP or geolocation
Use Cases for Rotating Proxies
- Web scraping or automation projects needing to avoid blocks
- Frequently changing geography or other attributes
- High volume of requests where costs would be prohibitive with static IPs
- Requiring fresh IPs with minimal blocks or reputation issues
Summary
In short, rotating residential proxies are ideal for most web scraping and automation tasks where you need to constantly vary IPs and require reliability. Static datacenter proxies work best for account management, location targeting, or other long sessions.
For advanced use cases, you can also leverage custom solutions like combining rotating IPs with sticky sessions for initial authentication then longer static sessions.
Frequently Asked Questions
What are sticky sessions?
Sticky sessions are when rotating residential proxies can maintain the same IP address for a set time period, such as 1, 10, or 30 minutes. This combines the benefits of rotation with longer static sessions when needed.
Are sticky sessions the same as static proxies?
No, sticky sessions are still provided by residential rotating proxies. The difference is static proxies persist indefinitely, while sticky IPs will eventually rotate despite holding the same address for a short period.
Conclusion
Choosing between static and rotating proxies requires understanding your use case and goals. For most web scraping and automation tasks, rotating residential proxies tend to be ideal for their reliability and ability to dynamically change IPs on demand. For account management or location targeting, static datacenter proxies may be a better fit.
