Pure IP Detection Method | The ultimate 3-step tutorial to quickly detect pure IPs.

First, what is "Pure IP"?

Many people think that as long as the use of proxy IP can solve the problem, the results found that the account is blocked, the operation is limited, the problem is in the IP is not clean. The so-called pure IP, have to meet three core conditions:Genre truth(e.g. home broadband rather than server room IP),Strong anonymity(without revealing agent traces),No historical stains(not frequently used by other users).

For example, if you use a data center IP to register accounts in bulk, the platform will directly recognize it as "robot behavior". The residential IP provided by ipipgo, however, comes directly from the real home network, and the IP database shows "residential broadband", so the success rate of the operation immediately rises.

II. 3-step practical testing method (with tools recommended)

Step 1: Detect IP type authenticity

Open a browser and visit an IP type checking website (e.g. ipinfo.io) and enter the proxy IP that is currently in use. focusing on two parameters:
– Hosting: "yes" means server room IP, "no" means residential IP.
– ASN: Data center IPs usually have AS numbers with keywords such as "cloud/hosting".

ipipgo users have a hidden trick: logging into the background can directly view the IP attribution type, residential IP will be labeled with a specific city and carrier, more accurate than third-party tools.

Step 2: Stress test for anonymity

Use a proxy IP to access both sites:
1. whoer.net (to see if the anonymous rating is >90%)
2. browserleaks.com/ip (checks if the HTTP header exposes the X-Forwarded-For field)

Focused observation:
- Presence of proxy protocol features (e.g., socks5 logos)
- Does the DNS match the IP location
For testing it is recommended to use ipipgo'sHighly anonymous proxy modelIt has been tested to hide all traces of proxies.

Step 3: Correlation ranking

Prepare three test dimensions:

III. Frequently Asked Questions QA

Q: How can I tell if an IP has been used by more than one person?
A: With ipipgo's exclusive residential IP function, the background can check the IP activation time, the first time the IP is absolutely "zero pollution".

Q: What should I do if everything is fine during the test, but it is recognized when I actually use it?
A: It is possible that the IP is not changed frequently enough. It is recommended to turn onSwitch IP on requestmode, ipipgo supports automatic IP refreshing in a single session to avoid behavioral correlation.

Q: What if I need to detect a large number of IPs at the same time?
A: Directly use ipipgo's API interface to obtain IPs in bulk, and with the self-contained IP health detection function, the purity screening of 100 IPs can be completed within 20 seconds.

Detection tools are no more powerful than source control of IP quality. ipipgo's90 million residential IP poolEach IP is given a 72-hour "cooling off" period before it is re-introduced to the market, and with intelligent routing technology, low-quality nodes are automatically filtered. The next time you do an important operation, remember to do a quick screening according to these three steps, you will find that the success rate is at least 3 times higher.
