Many crawlers will maintain a proxy IP pool by themselves, because the rented proxy IP pool will have many restrictions, such as the minimum extraction interval, how many seconds it takes to obtain a proxy IP. If you maintain a proxy IP pool by yourself, you can extract the proxy IP without intervals.
So how to maintain a proxy IP pool?
1. Get the proxy IP Most people will not build a proxy IP pool by themselves, but choose to rent a proxy IP pool. After all, the cost is too high and few people can afford it. Get the proxy IP from the rented proxy IP pool every few seconds, and get the proxy IP continuously.
2. Verify the proxy IP After each proxy IP is obtained, it is generally verified first. It is generally used to access a relatively simple website to detect whether the proxy IP is valid, how fast the access speed is, and filter out the effective retention and invalid removal.
3. Store in the local IP pool Store the proxy IP with a faster verification speed in the local IP pool. You can establish some necessary parameters, such as the proxy IP location, the remaining survival time of the proxy IP, etc.
4. Verify the proxy IP. Since the proxy IP is time-limited, although it has been verified and screened before being stored in the local IP pool, it is not guaranteed whether the proxy IP is still valid after a period of time. It is still necessary to verify and screen it again before using it.
5. Extract the proxy IP. Establish an API interface for the local IP pool. Through this API interface, you can obtain valid proxy IPs from the local IP pool for use without restriction. You no longer have to worry about "the extraction frequency is too fast, please wait for a few seconds before extracting again", and you can extract many proxy IPs at a time, which makes the work more efficient.
The above are some insights on how to maintain a proxy IP pool. I hope it will be helpful to everyone. The official website provides enterprise-level high-quality proxy IPs. Welcome to consult and purchase.
