Generally, crawler users cannot maintain the server or solve the proxy IP problem by themselves, because of the high technical content and the high cost. Of course, many people will put some free proxy IP on the Internet, but considering practicability, stability and security, we are not recommended to use free IP. Because the proxy IP published on the Internet may not be available, it is likely that you will find that the IP is unavailable or invalid, or take time to verify whether the IP is available. So now there are many proxy service providers in the market, which can basically provide proxy IP services for you.
Nowadays, it is a very common requirement for crawler programs to safely avoid anti crawler programs. When making web crawlers, there is a great demand for proxy IP. Since many websites adopt anti crawler strategies when capturing website information, they may control the frequency of each IP. Therefore, we need a large number of proxy IP when crawling websites.
The proxy IP can be obtained in the following ways: it is obtained from a free website with low quality and few IP addresses can be used. Considering the practicability, stability and security, it is not recommended that you use free IP.
Establishing your own proxy server is stable, but it requires a lot of server resources. One is because the technical content is too high, and the other is because the cost is too high. Therefore, it is more appropriate to directly use a provider that specifically provides proxy servers. It has special personnel maintenance and has a lot of resources.
