Residential Proxy IP Purity Test | Residential IP Purity Test Criteria

I. What is Residential Proxy IP Purity?

Simply put, purity is the key indicator to determine whether a residential IP is recognized as a proxy by the target website. For example, if you are prompted to require a CAPTCHA or are outright banned when you log into a website with a certain IP, it means that the IP is not pure enough. A truly clean residential IP will behave like a normal home network thatDoes not trigger any anti-climbing mechanismThe

Second, do-it-yourself measurement of IP purity of the 3 methods

Method 1: Simulate real browser access
Access social media (e.g. Weibo) through a proxy IP using Chrome's No Trace Mode. If there is a slider verification or account login anomaly, the IP may be flagged. Recommended to use the ipipgo provided byReal Behavioral Simulation Detection ToolIt can automatically generate fingerprint data for different browsers.

Method 2: Request Frequency Stress Test
Send 20 consecutive requests to the target site and record the response success rate. Here's a simple comparison table:

Method 3: Cross-platform calibration
Visit e-commerce platforms, search engines, and video sites with the same IP at the same time, and observe whether there are any abnormal tips on each platform. If an IP is restricted in Taobao but normal in Baidu, it means there is scenario-based wind control.

III. Testing standards for professional service providers

In the case of ipipgo, for example, the four-dimensional detection mechanism they implement is worth looking at:

1. Survival cycle validation:: Monitoring of IP continuous online hours, home broadband IPs are usually online continuously for 2-48 hours
2. Protocol Stack Depth Analysis: Detect underlying parameters such as TCP window size, TTL value, etc.
3. Geographical coherence: Comparison of filing areas by LBS base station location
4. Tracing the historical trajectory: Query whether the IP appears in the public blacklist database

IV. Practical Tips to Enhance IP Purity

Try when a drop in IP purity is detected:
– Switching ASN numbers: Selection of IP pools for different broadband carriers (ipipgo covers 600+ carriers worldwide)
– Adjusting session length: Simulate the rhythm of real users' surfing, avoiding visits at fixed time intervals
– Mixed Agent Types

: Dynamic IP for data collection, static IP for account maintenance

V. Answers to frequently asked questions

Q: What are the consequences of IPs with low purity?
A: Lightly reduce the success rate of business, seriously lead to account blocking, and even trigger the target site to strengthen the wind control measures.

Q: Are self-built residential agents purer?
A: Individuals build and maintain high cost and lack of professional testing mechanism. It is recommended to choose a service provider like ipipgo that has 90 million+ real residential IP pools.

Q: What is the appropriate frequency of testing?
A: High-frequency services are recommended to do a quick test every 15 minutes, and in-depth testing once a day is sufficient for regular services. ipipgo users can get IP health status in real time via API.
