Proxy servers play a very important role in network security and data privacy protection. However, sometimes we will encounter such a situation: the server can not use the public IP, so how to use the proxy IP? Let's explore this issue in depth.

Proxy servers cannot use public IPs

Usually, proxy servers communicate and transfer data through public IPs, but some servers may not be able to use public IPs directly due to some special network settings or security restrictions.This brings some difficulties in using proxy IPs. However, fortunately, we can solve this problem by some methods.

For proxy servers that cannot use public IPs, we can consider obtaining proxy IPs through specialized proxy service providers. These service providers usually provide various types of proxy IPs, including HTTP proxies, SOCKS proxies, and so on, and we can choose the appropriate proxy IPs according to our actual needs.

In addition, some proxy service providers will also provide proxy IP purchase and rental services, so that we can easily and quickly get the proxy IP we need, and then configure and use it on the server.

How to use proxy IP for servers

Once you get the proxy IP you need, the next step is how to use it on the server. Usually, we can configure and use the proxy IP by setting the server's web proxy parameters.

For Linux servers, we can specify the proxy IP by modifying the /etc/environment or /etc/profile file and setting environment variables such as HTTP_PROXY and HTTPS_PROXY, whereas for Windows servers, we can configure the proxy IP by locating the network proxy settings in the system settings and manually enter the proxy IP and port to configure it.

In addition, if our application or script needs to use a proxy IP to make network requests, then we need to set up the proxy accordingly in the program. For example, in Python, you can use the requests library to make network requests and specify the proxy IP address and port in the request.

In conclusion, although the proxy server can not use the public IP will bring some inconvenience, but through the appropriate proxy IP acquisition and server configuration, we can still realize the effective use of proxy IP. I hope this article can help you, thanks for reading!
