This article will explain in detail how to do ip agents for reptiles. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Ip proxies can be obtained in the following ways:

1. Get it from a free website, the quality is very low, and there is very little IP available.

2. For fee-based agency services, the quality is much higher.

3. Build your own proxy server, which is stable, but requires a lot of server resources.

If you want to have a crawler that can crawl information efficiently, the relevant system configuration must be in place. For example, for a network that requires high bandwidth, if the network level is too low and the average speed of a web page is only a few hundred kb, then you can basically give up the operation; because the stability of the proxy server is not very stable, a complete crawler should have its own fault-tolerant mechanism to ensure that the whole crawler can be crawled down in the end. Of course, if you want to crawl normally, you need a good conversion storage system to ensure that the data crawled by the program can be stored and used normally.

If you do not use proxy ip, you can only extend the interval time and frequency of requests in the process of crawling, in order to better avoid being banned by the server. Of course, if you have a large number of proxy ip resources, you can easily crawl.
