This article introduces the knowledge of "what are the common misunderstandings in the process of using agent IP by reptiles". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations.

1. Is the obtained proxy IP always available?

Not necessarily. The availability of proxy IP is related to many factors, such as the stability of user network, the stability of proxy server network and so on. Therefore, when the proxy IP is not available, it may not be a quality issue for the proxy IP. You can check the network first.

2. Is the effective connectivity rate equal to the business success rate? The business success rate of proxy IP is usually lower than the effective connection rate.

The successful connection of the IP agent does not mean that requests and information can be sent and obtained successfully. Many people will confuse the effective connection rate of the agent IP with the success rate of the business, and the merchants will deliberately confuse it when promoting it. When users see the effective connection rate of 99%, they think that the success rate of the business is also 99%. After buying it, they find that the success rate of the business is much lower.

3. Can the crawler task be completed after using proxy IP?

Not necessarily. Even if the proxy IP is used, it will inevitably be detected by the website anti-crawling strategy, but the probability of being detected will be reduced, and the use of proxy IP needs to be combined with good anti-crawling to play the greatest role. And the success rate of different agents IP visiting different websites is also different, which is also related to many factors.
