What is IP purity? How to test IP purity?

In the fields of network operation, social media marketing, cross-border e-commerce, etc., the quality of IP address directly affects the security and stability of the account. A "clean" IP address can reduce the risk of account blocking and increase access rights, while a "contaminated" IP address may lead to limited access, frequent pop-up verification codes, and even account blocking. So, what is IP purity ? How to detect IP purity? This article will give you a detailed analysis.

1. What is IP purity?

IP purity refers to whether an IP address has been used for malicious behavior, or whether it has been marked as "high risk" or "suspicious" by major websites or service providers. A clean IP is usually an address that has not been abused, blocked, or blacklisted, while a "polluted" IP may belong to a spammer, an abused proxy server, or a malicious crawler.

Factors that affect IP purity include:

• Blacklist records : If an IP is included in various blacklists (such as Spamhaus, Barracuda, etc.), its purity is low.
• Historical usage records : whether the IP is used for abnormal operations such as mass registration, spam sending, crawling, etc.
• Data Center vs. Residential IP : Data Center IPs are usually easier to be blocked, while residential IPs are relatively purer.
• Is it shared ? Dedicated IP is usually cleaner than shared IP, because shared IP can be abused by other users.
• Geographic location : IP addresses in certain regions may be inherently less clean because they are frequently used for malicious purposes.

2. Why is IP purity important?

Different scenarios have different requirements for IP purity, especially in the following areas:

• Social media operations (TikTok, Facebook, Instagram)
  When operating multiple accounts, if you use a low-purity IP, it may be identified as a spam account by the platform, resulting in frequent verification code verification or even direct account suspension.
• Cross-border e-commerce (Amazon, eBay, Shopify)
  Low-purity IPs may trigger the platform’s risk control mechanism, leading to account review, transaction restrictions, or store closures.
• SEO and data crawling <br>Many search engines will set limits on contaminated IPs. Using low-purity IPs may be blocked by search engines or have the crawling frequency reduced.
• Payment and Financial Services <br>Low-purity IPs may be identified as fraudulent IPs on payment platforms, resulting in transaction failures or account restrictions.

3. How to detect IP purity?

The methods for detecting IP purity mainly include the following:

1) Use IP blacklist query tools <br>Some specialized online tools can help check whether an IP is blacklisted, such as:

• Spamhaus ( https://www.spamhaus.org/)
• Talos Intelligence ( https://talosintelligence.com/)
• IPVoid ( https://www.ipvoid.com/)

2) Use IP reputation scoring tools <br>Some platforms provide IP reputation scoring. Common tools include:

• Scamalytics : Used to detect whether an IP has been involved in fraudulent activities.
• FraudScore : Provides an IP risk rating to detect whether it is being used for malicious operations.

3) Check the WHOIS information of the IP <br>Use a WHOIS query tool (such as https://whois.domaintools.com/) to view the registration information of the IP and determine whether it is from a data center (usually with lower purity) or a residential IP (usually with higher purity).

4) Use Google ReCAPTCHA test <br>When searching on Google, if the **"I am a robot" verification** is frequently triggered, it means that the current IP may be marked as abnormal by Google and has low purity.

5) Test website access <br>If you use a certain IP to access a specific website and find that verification codes are often required, access is restricted, or the loading speed is abnormal, it means that there may be problems with the purity of the IP.

4. How to improve IP purity?

If you find that your IP purity is low, you can take the following measures:

• Use high-quality residential IP proxies <br>Choose residential IP proxies with high purity, such as Kookeey proxies, to avoid the risk of blocking caused by data center IPs.
• Avoid overuse of the same IP
  When operating multiple accounts, it is recommended to use a dynamic IP proxy to ensure that each account has a different IP to avoid being identified as a batch operation by the platform.
• Regularly check IP status <br>Use the detection tools mentioned above to regularly check whether the IP is included in the blacklist and replace the contaminated IP.
• Reduce abnormal operations <br>Excessively frequent automated operations, batch registration, spam sending, etc. can easily reduce IP purity, and these high-risk operations should be avoided.

Summarize

IP purity is an important factor affecting social media operations, cross-border e-commerce, SEO optimization and other industries. A pure IP can improve the security of the account and reduce the risk of being blocked and restricted, while a contaminated IP may bring a series of operational problems. By using professional IP detection tools, properly managing IP usage, and selecting high-quality proxy IPs, you can effectively improve IP purity and ensure stable business operations.
