In the era of big data, we can't do anything without data. For data collection and analysis, data needs to be collected from different websites. However, if there are too many pages, individual pages cannot be captured separately, because it takes time and energy. At this time, we use programs to capture data. At this time, we need to use a proxy server, because the proxy server can break through the limitation of a single IP and collect a large amount of data.
Since the IP must be replaced, there will be a problem with the number of IP users. Because it needs to be replaced frequently, what if there is a large number of IP needs?
Everyone gathers a large number of proxy servers to manage and deploy IP pools. Their behavior characteristics are as follows:
1. The IP in the IP pool has a life cycle and will be checked regularly. Invalid IP will be deleted.
2. Continuously replenish the IP in the IP pool and add new proxy IP to the pool.
3. Proxy IP can be arbitrarily extracted from the IP pool.
The high-quality proxy IP pool will constantly update new IP, constantly verify IP, maintain valid IP and clear invalid IP. It is always active, just like a pool of running water. Therefore, IP plays a very important role in web page data collection.
Finally, Roxlabs brings a free experience of 500MB high hiding proxy server, including global IP resources. Tens of millions of IPS are available. By default, it is the rotation proxy for each browser session, and can be seamlessly integrated into any browser.
