The editor will share with you the reasons why reptiles need a lot of ip. I hope you will get something after reading this article. Let's discuss it together.

The reason why a crawler needs a lot of ip: 1, because in the process of crawling data, access is often prohibited by the website; 2, the data crawled is different from the normal data displayed on the page, or crawled is blank data.

Why do you need a large number of IP addresses to be a crawler? because in the process of crawling data, access is often prohibited by the website.

In addition, the data you crawled is different from the data normally displayed on the page, or you crawled blank data, which is probably due to a problem with the program that created the page; if the crawling frequency exceeds the threshold set by the website, access will be prohibited, so crawler developers generally deal with this problem in two ways:

One is to slow down the crawling speed to reduce the pressure on the target website. However, this will reduce the amount of crawling per unit of time.

The second kind of method is to break through the anti-crawler mechanism and continue to crawl with high frequency by setting proxy IP, but this requires a lot of stable proxy IP. Sesame HTTP agent IP, reptile workers can rest assured to use.
