ISP proxy is one of the proxy IP types that enables users to remain anonymous and less noticeable to the target web server. Web scraping provides numerous benefits to businesses, but it also poses its own challenges. Proxy servers help users avoid being labeled as a scraper. ISP proxies are distinct from other proxy services due to their unique capabilities. This article explores what are the differences between an ISP proxy and other proxies, as well as their advantages, and how to use ISP proxies for undetected web scraping. We will also examine the best ISP proxy providers along with their features.
What Makes ISP Proxies Unique?
Before diving into the top providers, it‘s important to understand what exactly ISP proxies are and how they differ from other proxy types like residential and datacenter proxies.
ISP proxies are static IP addresses that are hosted on data center servers instead of residential networks. This gives them some of the advantages of datacenter proxies, like speed and reliability, while still providing a good level of anonymity.
The key benefit of ISP proxies is that the IP addresses come from legitimate internet service providers (ISPs) like Comcast, Verizon, AT&T, etc. So when you use an ISP proxy, it appears no different than any other customer of that ISP accessing the website. This makes them very difficult to detect and block compared to datacenter proxies.
Another perk is that ISP proxies are static, meaning you keep the same IP address until you decide to rotate it. This allows you to maintain sessions and build trust, which is useful for certain use cases. But they still give you the ability to rotate IPs as needed.
In my experience managing large scale web scraping operations, ISP proxies provide the right balance of speed, anonymity, and control needed to extract data at scale without getting blocked. The additional cost over datacenter proxies is well worth it for the added capabilities.
The Top 6 ISP Proxy Providers
Now let‘s explore the top ISP proxy services available in 2024 based on extensive research and hands-on testing of over 12 different providers. I looked at key factors like the size of their proxy network, features, reliability, pricing, and customer reviews.

Comparing ISP Proxy Providers
To recap, here is an overview of how the top ISP proxy providers compare across key categories:
| Bright Data | Oxylabs | Smartproxy | NetNut | IPRoyal | SOAX | |
| Proxy Pool Size | 700,000+ | 40,000+ | 16,000+ | 1M+ | 2,000+ | 10,000+ |

As you can see, each leading ISP proxy provider has their own unique advantages. The right one for you depends on your specific use case, budget, and technical needs.
I always recommend starting with a free trial to test out proxies before committing. Most vendors also offer pay-as-you-go pricing if you want to start small.
When to Use ISP Proxies vs. Other Proxy Types
While ISP proxies offer significant advantages, it‘s important to understand when other proxy types may be more suitable depending on your use case:
Datacenter Proxies are best when you need sheer speed for basic web scraping at scale. They offer good bang for buck but are easier to detect and block.
Residential Proxies provide the highest level of anonymity but can have slower speeds and less stability than ISP proxies hosted on data centers. They work for sites vigilant about scraping.
Mobile Proxies simulate mobile device traffic by funneling your requests through real carrier networks. This is useful when scraping sites that restrict desktop access.
There‘s no one-size-fits-all proxy. The optimal approach is using a blend of different proxy types and providers tailored to each specific scraping use case.
3 Common Use Cases for ISP Proxies
Now that we‘ve compared the leading vendors, let‘s look at some of the most popular use cases where ISP proxies excel:
Use Case 1: Retail Competitive Price Monitoring
ISP proxies are extremely useful for monitoring competitor pricing data across ecommerce sites. Retailers need to gather prices for thousands of products daily across competitors without getting blocked.
By rotating ISP proxies and disguising scrapers as real users, retailers can collect pricing data at scale to optimize their own pricing strategy. This is extremely difficult to achieve with datacenter proxies which get detected more easily.
I worked with a home goods retailer that used ISP proxies to track prices for over 100,000 SKUs across their top 5 competitors each day. The data fed into pricing algorithms that dynamically matched and adjusted their own prices for competitive advantage.
Use Case 2: Social Media Account Verification
Many businesses need to verify social media accounts are real before engaging in high value transactions. Services like onboarding influencers or approving advertising campaigns require vetting followers and engagement.
ISP proxies allow you to appear as a normal user browsing profiles and posts on sites like Instagram and Twitter without rate limiting issues. Check for signs of fake followers and inorganic engagement patterns across thousands of accounts.
For example, I consulted for an influencer marketing platform that used ISP proxies and custom analysis scripts to identify fraudulent accounts before forming partnerships. This allowed them to avoid bad investments in inflated followings.
Use Case 3: Search Engine Results Scraping
Scraping search engine results pages (SERPs) can provide useful competitive intelligence. With ISP proxies, you can route requests through different locations and IPs to obtain the search results major engines like Google serve to users in specific cities, states, or countries.
Geographical targeting is possible because ISP proxies emulate requests coming from real residential networks in those areas. This grants access to localized SERPs businesses want to analyze.
I leveraged ISP proxies once to uncover search blindspots for a national hotel chain. By scraping Google Maps and localized SERPs for relevant keywords in all their major markets, we identified new targeting opportunities to increase visibility.
Best Practices for Maximizing ISP Proxies
Based on extensive experience using ISP proxies for large scale web scraping, here are my top tips for maximizing their capabilities:
Rotate IPs frequently – Never scrape too long from one ISP IP. Rotate at reasonable intervals to mimic natural user behavior.
Vary user agents – Rotate different user agent strings with each request to impersonate different devices and browsers accessing the site.
Use proxy manager APIs – Leverage tools like Bright Data‘s Proxy Manager API to automate IP and user agent rotation.
Monitor usage carefully – Track usage volume across IPs to avoid overusing individual IPs which can trigger blocks.
Employ throttle-bypassing tools – Leverage scrapers with built-in throttling avoidance to maintain speed despite blocks.
Funnel traffic through proxies – Route all scraper traffic through ISP proxies, not your own IPs for full anonymity.
Test extensively first – Thoroughly evaluate ISP proxies at small scale before deploying for large projects.
Following best practices like these ensures your scraping operation maintains performance, averts bans, and gathers data successfully over sustained periods.
Scraping Responsibly With ISP Proxies
While ISP proxies provide many benefits for web scraping, please remember to employ them responsibly:
-
Respect robots.txt – Avoid scraping sites that prohibit it.
-
Check terms of use – Don‘t scrape sites that ban scraping in their terms.
-
Scrape ethically – Don‘t use proxies to spread misinformation or copy content.
-
Limit volume – Monitor usage to minimize impact on target sites.
-
Use data properly – Respect privacy and data usage regulations.
-
Stay up to date – Monitor compliance issues and evolving legal standards.
By leveraging ISP proxies judiciously, you can unlock valuable data and insights without harming target sites or breaching ethics.
