This article introduces the relevant knowledge of "what is the importance of the crawler agent ip pool". In the operation of the actual case, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The agent is like a mask designed to hide the real IP. But the IP acting as a proxy is not hypocritical and does not exist; on the contrary, being able to act as a proxy IP must be a real IP address. In the real online IP address, there will inevitably be network delay, disconnection and other problems. When this happens, you need to replace the new IP agent to use it. Because to change, there is a quantity problem-two is still easy to solve, what if the number of changes is large, the quantity is very large?

This approach requires the use of a proxy IP pool, and we manage and provision a large number of agentable IP together to form an IP pool, which has the following behavior characteristics:

1. The ip in the IP pool has a lifecycle and should be checked regularly, and those that cannot function properly in these ip will be cleared.

2. Ip in the IP pool has been replenished, and new proxy ip will continue to be added.

3. The proxy ip of the IP pool can be extracted randomly.

The importance of proxy IP pools for crawlers! In this era of information big data, we feel that nothing can be done without data, and data analysis is carried out through data collection, then data collection is to crawl data from different websites, it requires a large number of pages, but just individuals crawl repeatedly, so it will waste a lot of time and energy, and it is impossible to spend so much time to get data, at this time everyone has to use crawlers to crawl data. This requires proxy IP, and proxy IP can break through the limitation of a single IP to achieve large-scale data collection.

An excellent proxy IP pool will constantly update the new IP, constantly verify the IP, retain the effective IP, remove the invalid IP, and always remain active, like a pool of running water, not a pool of stagnant water. Therefore, proxy IP plays a very important role for crawlers.
