The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "building method of exclusive ip"! Next, please follow the editor to study!

The unimpeded work of reptiles is the ideal working state for countless reptiles. But in fact, it is not difficult to solve this problem, as long as there is an exclusive IP pool, you can prevent the crawler from being blocked.

So the question we need to solve now is, how to have a unique pool of IP proxies?

Crawl free proxy IP and set up proxy IP pool

Purchase the agent IP, and establish the agent IP pool locally after obtaining the IP.

Purchase a batch of dial-up servers and set up your own proxy IP pool.

We can analyze which method is suitable for whom.

1. Grab the free agent IP and establish the proxy IP pool.

There are a lot of people using this method, because free is enough to make a lot of people flock to it. But let's take a look at the results. Some friends have tested it and crawled 108000 free proxy IP, of which only more than 100 are available. Suitable for beginners or tests. If you really work, you can't play for free.

2. Buy agent IP, set up agent IP pool, and buy agent IP friends are mostly professional crawlers or enterprises.

The time cost of representing IP for free is enough for them to drink a pot. Of course, they don't want to waste time, they can only spend some money. The effect must be much better than free. However, because it is a shared IP pool, it is inevitable to encounter various limitations in the process of use, such as extraction time and quantity.

Paid agent IP can meet the needs of most professional crawlers and enterprises, and there are always some special requirements for odd workers.

They want to extract more than one at a time and store them in a locally established IP pool. This method optimizes the scheme to some extent and is more convenient to use, but it also increases the maintenance cost, which is not perfect due to the influence of the validity period of IP.

3. Purchase a dial-up server and establish a proxy IP pool.

The perfect person chooses to purchase the dial-up server and set up the proxy IP pool. Spend a certain amount of money, buy a batch of dial-up servers, spend a certain amount of time writing code, or find some off-the-shelf software on the Internet, set up a proxy IP pool, and start crawling happily. It was really good in the early days. In the final analysis, it is exclusive and the effect is good.

But after a period of time, there will be such a problem, which takes a lot of time to maintain. Sometimes the problem is difficult to solve, very annoying, and the crawler task has to be completed every day. At this point, I can't wait to split myself in half to finish the task. Therefore, the establishment of their own agent IP pool, it is not that high-end players can not play, but need to increase a lot of maintenance costs.

It can be seen that the above three methods can establish a proxy IP pool. The first method can be used to play, for beginners to learn, it is difficult to be competent for formal crawler tasks. The second method can be applied to most formal crawler tasks, but is a little overwhelmed by some of the more demanding tasks. Although the third method can complete the task perfectly, it requires more fees, including dial-up server fees, technical fees, and the time cost of maintaining the agent IP pool.

At this point, the study on the "building method of exclusive ip" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
