What do crawlers mean when they hear the IP proxy? What are the differences between them?

Why do anti-bot service always need to use a high-speed proxy?

With these issues, the ant financial agent can unveil the anonymity level for you.

First anonymous: the server does not know that you have used the proxy IP address or the real IP address.
Second, anonymous: the server knows that you have used the proxy IP address, but does not know your real IP address.
Third transparent: the server knows that you are using the proxy IP address and that you are real IP address.

The high anonymous proxy does not change the client's request. In this way, the server looks like a real client browser is accessing it. In this case, the customer's real IP address is hidden, the server does not consider that we use a proxy.

Normal anonymous proxy can hide the real IP address of the client, but it will change our request information. The server may think that we have used the proxy. However, when using this proxy, although the accessed Website Cannot know your IP address, you can still know that you are using the proxy. Of course, some webpages that can detect IP addresses can still find your IP address.

Transparent proxy means that the client does not need to know the existence of a proxy server, but it still transmits the real IP address. Do not use this if you want to hide it.

As we all know, the proxy IP address is the foundation of crawler, and the high-availability IP proxy is the top priority of crawler proxy. It is totally sloppy. How to choose the high-availability crawler IP proxy, this learning is a little big, but I don't think we can simply introduce the name of the agency, because everyone does different businesses, which leads to different availability rates, this is not to say that the proxy is not good enough, but that the business model does not match. I suggest you test more and compare them, and select the best crawler proxy IP provider.
