How do web crawlers allow access to public data securely using proxy IPs?

Web crawlers have been a staple of the internet, primarily used for the collection of web resources and data. Search engines crawl content and save pages to generate indexes for user searches. Since the advent of the big data era, many industries have employed web crawlers to gather vast amounts of information for analysis and obtaining valuable data. Consequently, many websites have tightened their access control mechanisms to prevent unauthorized data collection, leading to the implementation of various anti-crawler measures.

These measures typically involve IP address detection to identify visiting users. When web crawlers excessively scrape the same website, the website's anti-crawler mechanisms often detect and prevent further access, fearing account association. Due to the scarcity of IP resources, regular users cannot access large numbers of IP addresses. Moreover, normal users do not typically browse and download pages at high speeds. Therefore, if a single IP address accesses pages at a fast rate, it may trigger the website's detection systems to identify whether it's a genuine user or a web crawler. If identified as a crawler, the website may allow access to public data or even permit data collection.

To address this issue, users can employ proxy IP tools. By using proxy IPs, users can access information without being detected as a crawler. When multiple users access information simultaneously using different IP addresses, the website is less likely to recognize them as crawlers. Additionally, users can use proxy IPs for multi-IP access, adjusting access speeds to mimic those of regular users, thereby avoiding detection by websites. These IP addresses can also be recycled for continued use. By employing multiple IP addresses, web crawlers can effectively prevent account association and enhance the efficiency of data acquisition.

IPHTML offers various types of proxy IPs to ensure users' network security in real-time. It has served numerous well-known internet companies, supporting API usage to prevent account association and enabling high-concurrency multi-threaded usage. Visit www.iphtml.com for more information.
