What this article shares with you is about how to build a dynamic IP pool. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

DynamicIP is the method of assigning IP addresses when needed. Accordingly, the dynamic IP address and the static IP address. What we mean by dynamic is that every time you surf the Internet, the telecommunications bureau randomly assigns an IP address; static means that you use this address every time and assign a fixed IP address. Next, let's take a look at the correct setup of the dynamic IP pool!

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

This method is used by a lot of people because it is free, and the word "free" is enough to make most people flock to it. If you don't know how to crawl, you can find many tutorials on the Internet and many entries on github, so you don't have to crawl here. If you are interested, you can find the code online or write it yourself.

2. Buy the agent IP and build the agent IP pool.

There are many friends who choose to buy agent IP. After all, the effect of free agent IP is not good. Although the charging agent IP has to pay a certain monetary price, the effect is obviously much better, but because it is a shared IP pool, it will always encounter restrictions of one kind or another, such as playing once in 5 seconds, or how many times it is extracted each time, how much concurrency is used, how many IP is bound, and so on.

Fee agent IP can meet most of the needs, but for some friends with special requirements, they want to mention several or more at a time and store them in the IP pool to establish a local. This method optimizes the scheme to a certain extent, makes it easier to use, and increases maintenance costs, and is not ideal due to the impact of the validity period of IP.

3. To buy a dial-up server, some people choose to buy a dial-up server and set up a proxy IP pool.

At a certain cost, buy a batch of dial-up servers, spend a certain amount of time writing code, or look for some ready-made software on the Internet, build the agent IP pool, and start crawling enthusiastically. After all, it is enjoyed by one person, and the effect is really good.

But after using it for a period of time, there will be similar problems, which will take a lot of time to maintain, even if sometimes there will be insurmountable problems, restlessness, and daily crawler work must be completed. Therefore, build their own agent IP pool, high-end players do not dare to play, but also need to increase the huge maintenance costs.

It can be seen that the above three methods can realize the construction of agent IP pool, the former can be used for play and learning for beginners, and it is difficult to be competent for formal crawler tasks. although the latter is suitable for most formal crawler tasks, it is somewhat inadequate for some higher demanding tasks. although the third method can complete the task well, it will also bring additional costs, including the cost of dial-up server. Technical expenses and time cost of maintaining the agent IP pool.

The above is how to build a dynamic IP pool, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
