In recent years, with the continuous advancement of web crawling technology, the use of IP addresses has become an essential strategy for developers.

However, some developers have encountered a significant issue when using IP addresses - the high repetition rate of IPs, causing considerable trouble in their crawling endeavors. This article explores the reasons behind the high repetition rate of IPs used by crawlers.

 

Why is the IP Repetition Rate High?

 

1.Limited Quantity of IPs:

The primary purpose of using IPs for crawlers is to conceal the real IP address and avoid detection and banning by anti-crawling mechanisms. However, the number of IPs, especially high-quality ones, is limited. This scarcity leads to multiple crawlers utilizing the same IP addresses, significantly increasing the repetition rate.

 

2.Usage of Free IP Providers:

Some free IP providers allocate the same IP to multiple users to attract more users. Consequently, the limited number of IPs provided by these free services, coupled with high demand, results in a high repetition rate.

 

3.Heavy Request Volume:

Crawlers often need to make numerous repetitive requests, such as repeatedly fetching a page for data updates. Even with different IPs, this heavy request volume contributes to an increased repetition rate.

 

4.Upgrade of Anti-Crawling Mechanisms:

The evolution of anti-crawling mechanisms, such as detecting crawlers based on IP access frequency, diminishes the effectiveness of using IPs. This necessitates developers to switch IPs more frequently, further exacerbating the repetition rate.

 

In summary, the high repetition rate of IPs stems from the limited quantity of IPs, allocation of the same IPs by free providers, heavy request volumes by crawlers, and upgrades in anti-crawling mechanisms.

 

Thus, developers should opt for high-quality IPs (how to buy IPs) and periodically change IPs to mitigate the repetition rate.

 

How Can This Issue Be Addressed? (Static Residential)

 

When conducting data collection through web crawling, IP usage is indispensable to evade detection and banning by anti-crawling mechanisms. However, the limited availability of IPs results in a high repetition rate, posing significant challenges for crawler developers.

 

1.Choose High-Quality IP Providers:

Opt for reputable IP providers offering a wide range of high-quality IPs that are not shared among multiple users. This helps reduce the repetition rate effectively.

 

2.Utilize IPs Reasonably:

Developers should use IPs judiciously, avoiding excessive requests to the same target website within a short period. Additionally, rotating between multiple IPs can lower the repetition rate and enhance data collection efficiency.

 

3.Regular IP Rotation: 

Due to the limited number of IPs, developers should regularly rotate IPs to avoid reusing the same ones. Monitoring IP usage and promptly replacing IPs with a high repetition rate can enhance data collection efficiency.

 

4.Utilize IP Pools:

IP pools facilitate automated management of numerous IPs, ensuring their availability is periodically checked. By leveraging IP pools, developers can effortlessly access a large number of high-quality IPs, thereby reducing the repetition rate and enhancing data collection efficiency.

 

Conclusion

In conclusion, to address the high repetition rate of IPs used by crawlers, developers should select high-quality IP providers and employ strategies such as reasonable IP usage, regular IP rotation, and utilization of IP pools. These measures not only improve data collection efficiency but also effectively prevent detection and banning by anti-crawling mechanisms.
