For crawlers, in order to prevent IP from being blocked during crawling, the most effective way is to choose to use proxy IP . Proxy IP can be said to be the golden partner of crawlers. Proxy IP can be divided into free and paid. Although choosing a free proxy can effectively save costs, the adverse effects are also huge. Let's take a look at why crawlers cannot use free proxy IP?
1. Low IP availability
In fact, there are a lot of free proxies, and because they are free, there are a lot of users. However, it is precisely because of the large number of users that the available resources are very limited. Of 10,000 free IPs, the number of usable ones may be less than 100, and the speed and stability are also very poor, which greatly increases your time cost!
2. Security cannot be guaranteed
The role of a proxy IP is to obtain network information on behalf of network clients. It is equivalent to a network information transfer station. Proxy IPs are divided into three types: transparent proxy, ordinary anonymous proxy, and high-anonymous proxy. Only high-anonymous proxy can achieve the purpose of hiding IP. Free proxies are transparent proxies, which will expose their real IP and their security cannot be guaranteed.
3. Accounts are vulnerable to being implicated
When we post, vote, collect information, etc., we will choose to use proxy IP to prevent IP restrictions. If you choose a free proxy IP, it is very likely that you will use it at the same time as others, and the risk of your IP and account being blocked will be greatly increased.
The above are the main reasons why crawlers cannot use free proxy IPs. In order to ensure work efficiency and the security of your own account, you must choose a stable and efficient proxy IP. The proxy IP resources provided by Kookeey are spread across 220+ countries around the world, with up to tens of millions of real residential IP resources per day, high speed and high availability. It has provided services to many well-known Internet companies, helping to improve the crawling efficiency of crawlers, supporting API batch use, and supporting multi-threaded high concurrency. The proxy IP pool also has professional responses, customer service responses are relatively timely, and it also supports free testing.
