Choosing the right proxy doesn’t have to be a headache. Whether you’re managing eCommerce accounts, collecting data, or verifying ads, the right proxy can be your secret weapon. Choosing the right proxy is crucial — the wrong pick could lead to overspending or underperformance. But how do you decide between ISP and residential proxies? This guide breaks down the differences — no fluff, no jargon — just the insights you need.
Let’s dive in!
Proxy Definition
Before we dive into ISP and residential proxies, let’s quickly define what a proxy is. A proxy server acts as an intermediary between your device and the internet, masking your real IP address and enhancing privacy, security, and performance.
What are ISP Proxies?
ISP proxies, also known as static residential proxies, operate in the middle ground between datacenter and residential proxies by being hosted in datacenter environments but also using IP addresses which belong to residential networks. They combine the authenticity of residential IP addresses with the speed and reliability of datacenter proxies.
Key Features of ISP Proxies:
1. Residential Authenticity: ISP proxies mimic genuine residential IPs, making them less likely to be flagged or blocked compared to traditional datacenter proxies.
2. High Performance: Leveraging robust datacenter infrastructure, ISP proxies offer fast and stable connections, outperforming residential proxies that rely on slower home networks.
3. Static Nature: ISP proxies maintain a consistent IP address over time, making them ideal for tasks that require stable identity or session persistence, such as account management, web scraping, and online advertising.
4. Cost-Effective Billing: ISP proxies are typically billed per IP address rather than per GB of bandwidth, making them substantially cheaper for bandwidth-intensive tasks. This flat-rate billing structure is advantageous for use cases like data scraping, media streaming, and other activities requiring high data throughput.
How ISP Proxies Work
Proxy providers are able to deploy ISP proxies by forming relationships with internet service providers and then requesting they deploy IP addresses on the proxy providers behalf. Once completed, this gives the proxy provider access to IP addresses which look like real residential connections - they link these to servers in a datacenter environment, set up their proxying software, and voila! You now have proxies that look like real home connections but with the stability, performance and IP address persistence of datacenter proxies.
Are ISP Proxies undetectable?
Not entirely. They use real residential carrier networks or ASNs, which cannot be blanket-banned without causing collateral damage to legitimate users unlike datacenter ASNs. Because of this, detection systems cannot simply impose ASN-level bans; they must instead look for proxy activity at the IP or subnet level.
They typically operate within small subnet ranges and if one IP is flagged, the entire subnet can be banned. Additionally, modern machine learning systems used by anti-scraping companies like Cloudflare, Datadome and Akamai can detect patterns of proxy use on these limited subnets because the activity from these IP addresses is similar and not as diverse as real traffic. Real residential proxies, on the other hand, are spread across huge, diverse IP address pools and different geolocations, making them far harder to isolate and ban. So while ISP proxies are more resilient than datacenter proxies, they are likely to be more easily detected than residential peer proxies.
Persistent, Stable IP Addresses
One of the standout features of ISP proxies is their ability to provide persistent and stable IP addresses for extended periods, often lasting months or even years. Unlike traditional residential proxies, which frequently change IPs due to the nature of home internet networks, ISP proxies maintain consistent IP assignments.
This stability makes ISP proxies an excellent choice for tasks requiring long-term reliability, such as:
1. Long-Term Account Management: Many platforms, especially social media and e-commerce, flag or lock accounts when IP addresses change frequently. ISP proxies' static IPs minimize these risks, ensuring seamless account operations without triggering security protocols.
2. Session Persistence: Tasks that require consistent session data, such as maintaining shopping carts, managing customer accounts, or running extended web scraping operations, benefit greatly from the unchanging IPs provided by ISP proxies.
3. Reduced Detection Risk: Because the IPs remain constant and are associated with residential ISPs, they blend in naturally with legitimate user activity, making them less likely to be flagged as suspicious or identified as proxies.
By combining residential authenticity with long-term stability, ISP proxies become a powerful tool for businesses and individuals who require reliable and undetectable solutions for extended online activities.
ISP Proxies Real-World Examples:
eCommerce Management: For instance, imagine you’re managing multiple eCommerce accounts that require high-speed connections. ISP proxies let you operate these accounts smoothly without raising red flags because your IPs appear residential but deliver the performance of data centers.
Digital Marketing: Also, consider a digital marketing agency managing multiple client accounts across different regions. ISP proxies allow the agency to switch between accounts seamlessly, ensuring tasks like posting content, analyzing engagement, and running ads happen without being flagged for suspicious activity.
Product Scalping: Picture yourself trying to snag limited-edition sneakers, event tickets, or collectibles the instant they drop. In these high-demand scenarios, speed is everything—slow connections can leave you empty-handed. Because ISP proxies offer residential authenticity plus datacenter-grade performance, they help you bypass typical blocks while also checking out items faster than competing scalpers. Essentially, you get the best of both worlds: legitimate-looking IPs that don’t raise red flags and the high-speed connections necessary to beat the competition.
Key Advantages of ISP Proxies
- High Anonymity: Authentic IP addresses that mimic real users, ensuring genuine-looking traffic and masking your true location.
- Exceptional Speed: Blazing-fast response times, ideal for data-heavy or time-sensitive tasks such as web scraping or rapid automation.
- Immediate Availability: Large pools of IP addresses readily accessible on demand, giving you the flexibility to switch IPs quickly.
- Customizable Sessions: Control session durations and rotation frequencies to align perfectly with your workflow or project requirements.
- Enhanced Security: Built-in safeguards help protect sensitive data, keeping your online activities safe from prying eyes.
- Cost-Effectiveness: Often cheaper than other proxy types since pricing is typically based on the number of IP addresses rather than bandwidth usage.
- Stable, Persistent IP Addresses: Offers long-term IP availability, reducing the risk of sudden IP bans or frequent reassignments.
Drawbacks of ISP Proxies
- Limited Locations: Fewer geographic options may hinder location-specific tasks.
- Smaller IP Pool: Limited subnets increase the risk of detection.
What are Residential Proxies?
Residential proxies use IP addresses from real household devices — such as PCs, laptops, and mobile phones—by Internet Service Providers (ISPs). Because these IPs come from genuine residential connections, they blend in with normal internet traffic. This makes them harder for websites to detect or block, and is a key reason why residential proxies are often considered the most popular type of proxy in scenarios that demand high anonymity and credibility.
How Are Residential Proxies Sourced?
The devices contributing residential IPs typically opt in—knowingly or through bundled software—and allow their internet connection to be used as part of a proxy pool. Proxy providers aggregate these IP addresses into large networks:
- Peer-to-Peer (P2P): Devices volunteer (or unknowingly install apps) that route requests through their connection.
- Partnerships & Opt-In Programs: Users consent to share their residential IP addresses in exchange for certain benefits, like free apps or credits.
By tapping into real household devices spread across different regions, residential proxies provide a wide geographic distribution of IP addresses.
Billing Model: Pay-As-You-Go on Bandwidth
Most residential proxy services charge based on the amount of data transferred (per GB) rather than a flat fee per IP address. Here’s why:
- Flexibility: Users only pay for the exact bandwidth they consume.
- Scalability: For smaller, targeted tasks, billing per GB can be economical.
However, for high-bandwidth operations, costs can add up quickly. If your project requires large data transfer (e.g., massive web scraping or streaming), you might consider alternatives like ISP proxies, which commonly use a per-IP billing model.
Why Residential Proxies Stand Out:
- Diverse IP Selection: Choose from a vast array of IP subnets to avoid detection.
- Highest Anonymity: Virtually untraceable, keeping your activities private.
- Global Coverage: Access geo-targeted options worldwide.
- High Success Rate: Efficiently bypass restrictions and detection filters.
- Increased Security: Rotating IPs conceal your real identity for added privacy.
Potential Drawbacks
1. Medium Speed: Residential proxies often rely on home internet connections, which can be slower and less stable compared to datacenter infrastructure or ISP proxies.
2. Variable Stability: Because residential IPs come from everyday home networks, connection quality can fluctuate due to the device owner’s internet conditions. If their connection is weak, temporarily offline, or heavily utilized, your proxy performance may suffer.
3. Shared IPs: Residential proxy pools typically share IP addresses across multiple users. If someone else misuses the same IP—spamming or engaging in illegal activity—it can end up on blocklists, affecting your projects.
4. Higher Cost for High Bandwidth Tasks: Most residential proxy providers charge per GB of data rather than a flat per IP fee. While this model is flexible for smaller tasks, it can become expensive if you need to transfer large amounts of data (e.g., intensive web scraping or streaming).
5. Lack of Persistent IPs: Residential proxies depend on the availability of real residential devices; you can lose access to an IP address at any time if the device is turned off or goes offline. This unpredictability makes residential proxies less suitable for long-term or session-based tasks (e.g., social media account management) that require a consistent IP over extended periods.

Which is cheaper? It’s Complicated
Comparing ISP and residential proxy pricing can get very complicated since each has its own pricing model and your actual costs depend on how much data you plan to transfer, how heavily a site rate-limits requests, and how many IP addresses you must maintain to avoid detection or bans on your target website.
ISP proxies typically charge a flat monthly fee per IP address, offering unlimited bandwidth. This can be a major advantage if you anticipate scraping a large volume of data—especially when dealing with sizable page downloads or high-scale web scraping. However, every additional IP address to circumvent rate limits also increases your total monthly bill. If the target website enforces strict concurrency requirements, forcing you to purchase hundreds or even thousands of IP addresses, costs can soar.
Residential proxies, on the other hand, are generally billed per gigabyte of data you transfer through then and tend to include unlimited IP rotations at no extra charge, so you do not pay separately for each new IP. Yet, if your data usage is large, per-gigabyte fees can add up quickly.
A simple formula can help compare the two:
In the first example, you might scrape 10,000 Amazon product pages per day, each 2 MB, adding up to 20 GB daily—600 GB monthly. With Amazon’s rate limit of 50 pages per IP per day, you need 10,000÷50=200 IPs. At $3 each, ISP proxies cost $600 (200×3) for unlimited data. Residential proxies at $5/GB would cost $3,000 (600×5), so ISP is cheaper here.
In the second scenario, you want to scrape 100,000 Amazon pages in one hour, each page 1 MB, but the site caps you at 10 pages per IP per hour. You therefore need 100,000÷10=10,000 ISP IPs. At $3 each, that is $30,000 for the month. Even if you only do this heavy scrape ten times (1,000 GB total), residential proxies at $5/GB would cost $5,000—far less than $30,000.
Ultimately, the cheaper option depends on your total data usage and the number of IPs you need to handle rate limits. By carefully weighing both bandwidth requirements and concurrency constraints, you can determine whether ISP or Residential proxies offer the better deal for your specific project.
Choosing the Right Proxy for Your Business
Selecting the best proxy type depends on your specific use cases. Here’s a more detailed guide:
When to Use ISP Proxies
