Nowadays, many people in network-related industries or working on the Internet often use IP proxy tools in their mobile phones or computer equipment to assist their office. What is its role? Why do you need to use it to surf the Internet? Because the network settings are particularly complicated. Frequently visit a certain webpage with the same IP address or log in and operate multiple accounts with the same IP address, which results in its current IP address being restricted or IP being blocked. In the case of blocking, you need to use an IP proxy to change the IP software at this time . After connecting to the proxy software, you can obtain a new IP address for network access, avoiding the situation that the network cannot be used normally due to IP blocking. Among them, IP proxy is subdivided into the following categories. The following editor will talk about its types and differences.
1. Local Forwarding Agent
The proxy information is extracted locally through software, and then process or global proxy is performed. Because its technical framework cannot realize automatic mass IP pool management and load balancing guarantee, it can only submit the forwarding IP to the terminal software, and the software realizes HTTP through multi-thread switching. The forwarding of requests makes the crawler framework complex and difficult to maintain. At the same time, the efficiency of IP switching is low and the IP failure rate is high.
2. The crawler proxy
establishes a dedicated network connection through a fixed proxy service address. The proxy platform automatically realizes mass IP pool management and load balancing, real-time and non-inductive millisecond-level proxy IP switching, and at the same time reduces client computing load pressure and avoids crawler customers Putting effort into the optimization of the proxy IP strategy has improved the crawler efficiency overall.
3. API extraction proxy
obtains proxy IP information through URL. The format is generally IP:PORT. It is necessary to verify the availability of IP, change proxy settings, and also need to design multi-threaded asynchronous IO to achieve concurrent processing of proxy IP, which is not only cumbersome, but also affects efficiency. , You can build your own IP pool control.
The above is some knowledge sharing about IP proxy, and IP proxy in the IP sea covers ip resources in many regions in China, low-latency static IP, dynamic IP, and meets the needs of changing different IPs.
