Internet workers all know that when crawlers are crawling data, they may encounter websites that use anti-crawler technology, which will directly lead to the failure of crawlers to collect data and also bring huge pressure to the user's server. Therefore, in order to avoid such a situation, users basically let crawlers use proxy IP or dynamic IP. Today, let's analyze in detail why crawlers need proxy IP and dynamic IP.
Why do crawlers need proxy IP and dynamic IP?
The main reason why crawlers need proxy IP and dynamic IP is to resist anti-crawler technology. As we all know, when crawlers collect data, they need a lot of clicks and page visits, which will bring huge pressure to the queried website. In order to reduce the pressure, the website will turn on the anti-crawler technology, which will easily lead to the failure of crawlers when collecting data. Therefore, in order to fight against the opponent's anti-crawler technology, the crawler must rely on the proxy IP to forge the IP, thereby hiding the identity and making it difficult for the website to identify. In addition, it also needs the dynamic IP to constantly change the IP address, so as to disguise the true identity and make data collection successful. In addition, in order to collect more data, the crawler must rely on proxy IP and dynamic IP to increase the running speed, break through network restrictions, and set up a firewall protection agency for itself, so as to effectively promote the development of the crawler business.
How to get a dynamic proxy ip?
There are three ways to get a proxy IP dynamic IP. First, you can crawl to a free proxy IP. However, this kind of free proxy IP is often used by others and is not very stable. If you want to do business, this method is not recommended.
Second, build your own server. This method can obtain a proxy IP, but the operation process is more costly and technical, and even if it is done well, the effect is not very great.
Third, go to the relevant agency to purchase. Compared with the previous two methods, purchasing a proxy IP is more reliable. Because most of the agencies that sell proxy IPs are professional agencies, such as Kookeey, which can 100% guarantee that the proxy IPs sold have not been used by anyone, and the quality stability is relatively good. Whether it is an individual or an enterprise, purchasing a proxy IP through Kookeey can greatly solve related problems and improve efficiency. It can be said that this method is the most cost-effective.
The above is about why crawlers need proxy IP and dynamic IP. Of course, proxy IP and dynamic IP are not only used in crawlers. For example, corporate operations or sales also require proxy IP. Therefore, paying attention to proxy IP can promote improvements in all aspects.
