Engineers who write web crawlers know that no matter how meticulously you write your code, if your IP is blocked, all your efforts will be wasted.
You may have encountered this situation: everything works fine during local debugging, but after running it online for half an hour, it starts returning 403 errors; you enabled multithreading to improve efficiency, but the website immediately pops up a CAPTCHA; you want to scrape data from an overseas website, the requests are sent, but the returned content is all localized versions.
These problems are almost always related to your IP.
Different scraping tasks have very different IP requirements. Before choosing an IP, think about three questions:
First, how strict are the anti-scraping measures on the target website?
Platforms like Google and Amazon are highly sensitive to abnormal IP addresses. Data center IP ranges are typically under close monitoring and are quickly identified. These scenarios require native residential IP addresses—originating from a stable network access environment, similar to that of ordinary users, making them difficult to distinguish.
If using publicly available data sources with less stringent anti-scraping measures, the requirements for IP purity can be relaxed.
Second, how many requests will you send per day?
The volume of requests determines the size of your IP pool. A few hundred requests can be handled by rotating a few IPs. With hundreds of thousands of requests per day, you’ll need at least several hundred to a thousand IPs, and a corresponding rotation strategy.
Third, should you differentiate by region?
If you’re only collecting domestic data, it’s simple. But if you need to collect prices from Amazon US or product information from Rakuten Japan, you must use IPs from the corresponding countries. Otherwise, the content you see will differ from what local users see, rendering the collected data worthless.
There are many IP service providers on the market, and their promotional materials are quite impressive. How do you judge their actual quality? You can look at five aspects:
IP purity
Ask your service provider: Where does the IP address come from? Is it from a stable network access environment or a data center IP address? Has it been abused in the past?
Fluxisp is relatively transparent in this regard. Over 110 million IPs come from legitimate ISPs and have legal authorization. Using such IPs to request sensitive websites has a lower probability of triggering CAPTCHAs.
Stability
If an IP address keeps disconnecting, data collection tasks can’t run. Fluxisp boasts a 99.92% stability rate, with 24/7 online operation tested. This means that running a long-term, large-scale data collection task is largely worry-free due to connection issues.
Response Speed
Slow response times mean slow data collection. Fluxisp’s average response time is less than 0.5 seconds, with cross-border latency between 0.3 and 0.8 seconds. This speed is sufficient for most data collection scenarios.
Concurrency Capability
Many IP services only support a few dozen concurrent connections per IP, crashing under slightly higher loads. Fluxisp, in testing, can run 500 threads per IP, demonstrating strong concurrency capabilities. This saves considerable effort in high-concurrency data collection scenarios.
Regional Coverage
Fluxisp covers over 195 regions and supports city-level positioning. Need data for New York? It can provide New York IPs. Need data for Tokyo? It can provide Tokyo IPs. Accuracy is tested to be over 98%.
This section deviates from the typical “Scenario 1, Scenario 2” approach and directly discusses IP pairings for several common scenarios.
Sampling Search Engine Ranking Data
These websites have strict anti-scraping measures. Using data center IPs is essentially suicide. Dynamic residential IPs, coupled with a rotation strategy, are recommended. Fluxisp’s dynamic residential IPs are billed per GB at $0.49, suitable for this type of high-frequency, short-term task.
Sampling E-commerce Platform Product Information
The key is to obtain authentic local data. For example, when sampling Amazon US, US IPs are recommended, especially city-level ones. Fluxisp supports city nodes such as New York and Los Angeles, allowing you to obtain pages that are actually seen by local consumers.
Long-Term Data Collection Tasks
Some data collection tasks run continuously, such as monitoring a batch of keywords daily. Static ISP IPs are recommended for these tasks, as the IPs are fixed and do not need frequent changes. Fluxisp’s static IPs are as low as $2 each; buy several and bind them to different tasks for stability and peace of mind.
Mixed Use Strategy
A mixed approach can also be used. Use static IPs for core tasks to ensure stability, and dynamic IPs for temporary large-scale data collection to reduce costs. Fluxisp supports both modes; simply switch as needed.
Here are a few more practical and useful tips:
Don’t be too aggressive with request intervals
A common reason for being blocked is making too many requests. The specific interval depends on the target website’s tolerance. It can be adjusted dynamically: one request per second for normal pages, and one request every 3 to 5 seconds for sensitive pages. Slower is more stable.
Change IPs systematically
Don’t cycle through all IPs in a very short time; this pattern is easily detected. It’s recommended to change IPs after every N requests. N can be adjusted based on the workload, for example, between 20 and 50.
Implement retries effectively
Network request failures are very common. Your code must include retry logic to automatically change IPs and re-request after a failure. Fluxisp supports quick IP retrieval via API, making this logic easy to implement.
Lazy Person’s Solution
If you don’t want to bother with these parameters yourself, Fluxisp also provides an SDK available in Python, Java, and PHP. Integration takes only minutes, and basic configurations are ready to use.
A data service team previously collected prices from 20 global e-commerce websites daily, with an average of 500,000 requests per day.
Their original data center proxy had a 30% blocking rate, meaning one in three requests was blocked. Data integrity was less than 70%, and prices for many key products were simply unavailable.
After switching to Fluxisp’s dynamic residential IPs, combined with a simple rotation and retry strategy:
Blocking rate dropped from 30% to below 5%
Data integrity improved from less than 70% to around 95%
Daily data collection time decreased from 8 hours to 3 hours
This case illustrates that often the problem isn’t with the code, but with the wrong IP selection.
In the data collection industry, both coding skills and IP quality are crucial. No matter how well-written the code is, if the IP quality is inadequate, the task will still be difficult to complete successfully.
When choosing IPs, don’t just look at the price. IP purity, stability, accurate coverage, and concurrency handling are all more important than price. When calculating costs, factoring in the time cost of retrying failures and the loss of data is often more meaningful than simply comparing prices.
Fluxisp excels in purity, stability, coverage, and developer friendliness. With a free trial, new users can test it before deciding, with minimal risk.

Q: What’s the difference between residential IPs and data center IPs?
Residential IP addresses come from stable network access environments, similar to those of ordinary users, making them difficult to identify. Data center IP addresses, on the other hand, come from data centers, and these IP ranges are under close monitoring, making them more susceptible to blocking.
Q: How to choose between dynamic and static IPs?
Use dynamic IPs for short-term, large-scale data collection for easy rotation; use static IPs for long-term, fixed tasks for stability and peace of mind. Fluxisp offers both HTTP and Socks5 protocols, allowing for mixed use.
Q: Is Fluxisp integration complicated?
No, it’s not. It supports both HTTP and Socks5 protocols, and can be integrated with most mainstream web scraping frameworks. The documentation is comprehensive, and SDKs are available for Python, Java, and PHP, so it can be set up in minutes.
