ISP vs. Datacenter Proxies: An Overview

Before we get into the nitty-gritty details, here’s an overview for anyone in a rush.

Proxy servers act as middlemen between you and the internet. They shield your IP address and (hopefully) fool websites into thinking you’re browsing from a different device or location. The differences lie in how they do this.

ISP proxies use an IP address assigned by your internet service provider (or ISP). This gives the IPs a legitimate and traceable source, which means websites are likely to trust them. On the other hand, datacenter proxies use IP addresses from datacenters, which typically have a higher volume of IPs and are not traceable back to an ISP.

Now, let's dive in a little deeper.

What Are ISP Proxies?

ISP proxies (or static residential proxies) combine the features of datacenter and residential proxies.

They are hosted on datacenter servers, but the IP addresses they use are assigned by ISPs. This gives them a good balance of speed and legitimacy. They are a popular choice for tasks such as web scraping, social media management, and other online activities that require a high level of anonymity.

How Do ISP Proxies Work?

Here’s a step-by-step explanation of how ISP proxies work:

1. Acquisition of IPs: The process technically begins when the proxy provider purchases a large pool of residential IPs from ISPs. These IPs are then assigned to datacenter servers, which act as the middlemen between your computer and the websites you visit.
2. IP Assignment: When you sign up with an ISP proxy provider, you are allocated a specific IP address from their pool. This IP address will be used as your entry point into the internet.
3. Traffic Routing: When you make an online request, it first goes to the datacenter server, which then forwards it to the target website through one of its IPs. This process is known as traffic routing, allowing you to browse anonymously without revealing your IP address.
4. Receiving Data: Once the request reaches the target website, it sends back data to the datacenter server through the assigned IP address. The data is then forwarded back to your computer, making it appear like the data was received from the proxy server and not your device.

In other words, an ISP proxy server is an intermediary between you and the website you are trying to access.

Features of ISP Proxies

• Static: ISP proxies are sometimes called “static residential proxies” because they are assigned a fixed IP address.
• Balance of Speed & Cost: ISP proxies offer a great balance of speed and cost since they’re hosted at high-performance datacenters and can handle a large amount of traffic.
• Legitimacy: ISP proxies use IPs that appear to be legitimate and are less likely to get you blocked or banned when accessing websites.

What Are Datacenter Proxies?

Datacenter proxies are very similar to ISP proxies - both act as an intermediary between you and the internet, both are hosted at datacenters, etc. The difference is that the IPs owned by a datacenter proxy provider didn’t originate from an ISP. Instead, they were generated in bulk by a server farm.

So, unlike ISP or residential proxies (which are designed to mimic real user traffic), datacenter proxies are completely artificial. As a result, it’s pretty easy for websites and servers to tell that you’re using a datacenter proxy - and it’s up to them whether to allow it.

How Do Datacenter Proxies Work?

Datacenter proxies function by routing a user’s request through a server housed within a data center.

These servers are equipped with IP addresses that are owned and managed by the hosting company rather than being directly associated with an ISP that supplies internet services to residential or commercial customers.

Here’s how datacenter proxies work:

1. IP Generation: The first step in using a datacenter proxy is generating an IP address. This is typically done by the hosting company within their data center.
2. Request Forwarding: When users connect to a datacenter proxy, their requests (e.g., clicking a link or submitting a form) is forwarded to the proxy server.
3. IP Masking: The proxy server then processes the request using one of its IP addresses. This masks the user’s original IP address, making the request appear to originate from the proxy server’s location within the data center.
4. Data Retrieval: The server at the requested website responds to the proxy server’s request, unaware that it is a proxy acting on behalf of the user.
5. Response Delivery: The proxy server receives the data from the website and forwards it back to the user, completing the request cycle.

Features of Datacenter Proxies

• Speed and Efficiency: Datacenter proxies are known for their high speed and efficiency. Since they are hosted in data centers equipped with robust hardware and high-speed internet connections, they can process requests much faster than residential proxies.
• Cost-Effectiveness: Generally, datacenter proxies are more affordable than residential or ISP proxies. This is because they are easier to maintain, and the infrastructure is designed to handle large volumes of traffic, making them a cost-effective solution for businesses and individuals who need proxy services.
• Detectability: Websites can sometimes identify datacenter proxies due to tell-tale patterns within their IP addresses. For example, datacenter IP addresses come from large blocks owned by hosting companies or cloud services, which websites can flag as non-residential and potentially automatic traffic.

ISP Vs. Datacenter Proxies: 5 Key Differences

1. IP Address Source

The most fundamental difference between these two kinds of proxies is the source of their IP addresses.

ISP proxy providers purchase IPs from ISPs in bulk. As a result, those IPs are registered to a specific residential address, making them appear as regular traffic.

On the other hand, datacenter proxy providers obtain their IPs from hosting companies or cloud services (or generate them in bulk themselves). These IPs are not assigned to any physical location and can be used by multiple users simultaneously.

2. Anonymity and Detectability

Both ISP and datacenter proxies are great at anonymizing your traffic. It’s almost impossible for a website or server you access to identify you as an individual user. The difference here lies in detectability - how easy it is to identify that your traffic originated from a proxy.

ISP proxies are very hard to detect, since the IPs they use resemble residential addresses. This means that websites or servers won’t be able to tell that you’re using a proxy, making it easier to access geo-restricted content or avoid being blocked by certain websites.

Datacenter proxies are much more easily detectable. If a website has decent security measures in place, they will be able to identify that you’re using a datacenter proxy and can potentially block your access (although most won’t).

3. IP Rotation

ISP proxies are typically static, meaning that the same IP address is used every time you connect to the internet. However, some providers will have tools in place for periodic IP rotation to prevent IP blocking or blacklisting. With datacenter proxies, IP rotation is rarely an option.

If you are looking for IP rotation, mobile and residential proxies are your best bet. Both offer a pool of IP addresses that rotate with each request, making it much more difficult for websites to detect and block your access.

4. Cost

Datacenter proxies are typically the cheapest kind of proxy available. Since IPs are generated artificially, it’s very cheap for providers to set up and maintain a large number of datacenter proxies. However, with low cost comes lower quality and less anonymity.

For those same reasons, ISP proxies are typically more expensive (though still more affordable than residential proxies). Since the provider needs to purchase, maintain, and manage the IPs, the cost is passed on to the customer.

5. IP Pool

The IP pool for ISP proxies is typically smaller than datacenter proxies, as they are limited to the IPs allocated by ISPs. Datacenter proxies have access to a large pool of IP addresses, which makes them suitable for scaling operations without the risk of overusing a single IP.

When Should You Use ISP Proxies?

ISP proxies strike a perfect balance between anonymity and speed, making them ideal for tasks that require good anonymity but also demand faster speeds than typical residential proxies. They are handy in scenarios that necessitate maintaining a consistent online identity over extended periods.

Furthermore, ISP proxies present potential cost benefits for large-scale projects with budget constraints.

Let’s take a look at how digital marketers typically use ISP proxies.

Use Cases

• Web scraping: ISP proxies work well for web scraping thanks to their steady IP address that websites rarely block. Their speed and stability help collect lots of data quickly.
• SEO Monitoring: For purposes like keyword tracking and website tracking, ISP proxies' reliable and fast connections are essential for efficient data collection and analysis.
• Social Media Management: Managing several accounts is easier with ISP proxies, as they don’t set off security blocks, maintaining account integrity.
• E-Commerce and Market: ISP proxies help collect accurate data from e-commerce sites and conduct market research without getting caught as proxies.
• Lead Generation and E-commerce Management: ISP proxies give businesses stable and legitimate web access for generating leads or running online sales.

When Should You Use Datacenter Proxies?

In scenarios where speed and affordability are your top priorities, datacenter proxies are the go-to choice.

They shine in situations where the highest level of anonymity isn’t necessary, but the actual IP address still needs to be masked. They are handy in tasks where sophisticated anti-bot solutions are less likely to be encountered.

Use Cases

• Testing and Basic Data Gathering: Datacenter proxies are helpful in environments where anti-bot countermeasures might be less sophisticated, allowing for straightforward data collection.
• Cybersecurity Enhancement: Datacenter proxies can simulate attacks from various locations to identify and patch network vulnerabilities.
• Market Research: Datacenter proxies enable efficient web scraping, essential for gathering data to inform decision-making, conducting market and competition research, comparing prices, and identifying trends.
• Brand Protection: Companies can use datacenter proxies to monitor for counterfeit goods and protect their brand by parsing data from marketplaces and e-commerce sites.
• Ad Verification: They help detect ad fraud, ensure ads reach the right audience, and improve ad performance.

Conclusion

Choosing between ISP and datacenter proxies depends on the user's needs. ISP proxies balance legitimacy and performance, which is ideal for tasks needing speed and stealth. They use real residential IPs for enhanced authentication, reducing the risk of detection by advanced anti-bot systems.
