In the Internet age, people are now interested in big data. A reptile. Code. Proxy server. These words are no longer unfamiliar. Now, why does proxy IP become standard for reptiles? Can you crawl without a proxy IP?

1. When a crawler catches the data of a site, it is tantamount to constantly saying hello to others, and is likely to go black.

Replace a different IP with a proxy IP, and the other site thinks it is a new user every time, so there is no danger of blocking.

2. When crawling, the crawled website has an anti-crawler mechanism. If you use an IP to visit a web page repeatedly, it is easy to be restricted by IP and can no longer visit the website. At this time, you need to use proxy IP.

If the volume of business is small and there is no great requirement for work efficiency, you don't have to use proxy IP. If the amount of work is large and the fetching speed is fast, the target server will be easy to find, so it is necessary to use proxy IP to exchange and fetch the IP.

After the above introduction, it shows that web crawlers do not have to use proxy IP, but it is indeed a good tool to work effectively.

Especially at present, the scale of data collection is getting larger and larger, and the amount of data and samples that need to be obtained is also large, so large-scale crawling still needs to use a proxy IP with stable quality.

In the era of big data, data collection has become an indispensable part. In the process of data collection, many people will use proxy IP, so do web crawlers have to use proxy IP? Although the answer is not in the affirmative, a proxy IP must be used in the following situations.
