With the advent of the big data era, crawlers have become an indispensable way to obtain data. However, due to website restrictions and other prohibitions, crawlers are often blocked when visiting the same website multiple times. In order to solve the problem, the government usually uses proxy IP. So, what is the importance of proxy IP to crawlers? Why is it important?
What is the importance of proxy ip for crawlers?
The most important thing about using proxy IP is to forge a real IP for the crawler. The website's ban basically has a huge impact on fake IPs, and after the crawler has a real IP, it can quickly and efficiently collect multiple layers of information without changing itself. Moreover, many proxy IPs can also automatically modify the IP address, which greatly avoids the phenomenon of being unable to query due to the untimely change of IP. Therefore, if you want the crawler to break through the anti-crawler mechanism and efficiently crawl data, proxy IP is essential.
Where is the importance of proxy IP?
In addition to being able to forge real IPs, proxy IPs also have the following three important features: First, they can be used as firewalls. Because proxy IPs are transit stations, it is not easy for outsiders to see the real IP. If they are violated, proxy IPs can act as a barrier. Similarly, if someone outside wants to access the internal, the proxy IP can also deny the other party's access.
Second, it can save costs. When crawlers crawl data, they need a large number of IP addresses. Using proxy IPs can quickly and efficiently convert IP addresses, reducing the cost of users applying for IPs and maintaining the network.
Third, it can also facilitate user management. The amount of data crawled by the crawler is large, and the proxy IP can perform information flow statistics to a certain extent, allowing users to manage and set it more conveniently. This function is quite convenient for both individuals and enterprises.
In short, a good proxy IP can improve the efficiency of crawlers in grabbing data and enhance user management. Therefore, we must pay great attention to the selection of proxy IP. There are three ways to get a proxy IP nowadays. The first is to build it yourself, which requires very strong technology and cost. The second is to find a free one on the Internet, but because the quality of the IPs found will be unstable, it is not recommended. The third is to buy it from relevant institutions, such as Kookeey. Going to Kookeey to buy an IP is a better choice. It is low in price and good in quality, which can bring great convenience to users.
The above is about the importance of proxy IP to crawlers. If you want to obtain more data, you must pay attention to proxy IP.
