Dynamic proxy IP, literally speaking, this IP will change randomly at any time and is not fixed. It is a dynamic proxy IP. Dynamic proxy IPs are generally used by web crawler users.
Dynamic IP is divided into long-term proxy and short-term proxy:
long-term proxy IP : Supports many services such as data collection or game hang-up. Since the amount of data collected by web crawlers is relatively large, long-term proxy is rarely chosen. The long-term proxy IP is equivalent to the local IP. After visiting a website for a long time, the natural IP It will also be limited, and the amount collected is very small. Not conducive to crawler use.
Short-term proxy IP: Supports data capture, seo optimization, APP brushing, Q&A promotion and many other businesses. Generally, more web crawler users choose dynamic short-lived proxy IPs. The business volume of crawlers is large. Using dynamic short-term proxy IP for data collection can greatly improve business efficiency.
Dynamic proxy IP is also divided into transparent proxy, Anonymous proxy , High anonymous proxy.
This shows the quality and strength of the proxy IP. For web crawlers, you can purchase customized dynamic IP according to your own needs.
高hidden proxy is naturally one of the best quality dynamic proxy IP types. Many enterprise crawler users will choose tunnel forwarded high-hidden crawler proxy IP to provide business needs. , to ensure the effectiveness and quality of your business.
Transparent proxy and Anonymous proxyAlthough they are also proxy IPs, they greatly reduce the progress and efficiency of the crawler business, so the web crawler chooses the crawler proxy for tunnel forwarding. Make the right choice.
Simple This article introduces the concept and benefits of dynamic proxy IP, and then talks about how to apply for this dynamic proxy IP.
I am using the IPIDEA website here. Now new users have 500M traffic for free, which we can use for experiments.
You can just click to register: http://www.ipidea.net/?utm-source=csdn&utm-keyword=?xy
After entering the website, click to get the agent- > API gets
and then selects quantity and region according to your own preferences. For other things, use the default options, and then Click the below to generate the link
If there is no real-name authentication, this interface will pop up, just click authentication
Then copy the link we generated. This link should be saved and will be used later when crawling with Python.
Copy the link separately and then open it, you will see the IP just generated. This part can be used for manual setting of our own browser.
As mentioned above, there are currently many websites that act as IP agents. How to choose the right platform is also a question worth thinking about.
Since there are currently many proxy IP websites, the prices vary greatly based on stability and security.
IPIDEA new users will receive a portion of free traffic when they register, which is very friendly to our friends who want to try using proxy IP.
Also, the platform supports residential dynamic IP, which is also an advantage.
Benefits of dynamic residential IP:
Proxy ip There are many ways to use it. Below I will give a simple demonstration by using it directly in the browser and using the generated API link.
In the previous step, we obtained an ip proxy pool, and then use QQ to browse Server example, briefly look at how to use these proxy IP.
In the QQ browser menu list - Settings - Advanced - Network - Change proxy server settings
In the pop-up Internet properties window, click LAN Settings
Fill in the ## we copied #IP and Port number, and click OK
Open Baidu/Google search engine, search:
IP, Check the current IP address behind the proxy
At this point we have successfully used the
proxy ip, and then we can use the proxy ip to do other things~
Note: Only supports use in overseas network environments and does not provide any form of domestic use. Way.
But this is just the simplest usage. A more advanced one should be to use the dynamic IP proxy pool to achieve a better effect when using a crawler. Let’s simply write an example of using proxy IP to access the github python module.requests module directly, and then add a random request header module
fake_useragent and
UserAgent.
github python module. The interface content is as follows:
This just demonstrates the use of proxy ip to crawl the github python module, and make good use of
dynamic proxy ip It can be used There are more things to do, so let’s experience it by yourself!
