Anyone who understands a word can follow the steps of DIY proxy servers by themselves.

[Proxy Server] As the name suggests, it is a substitute for other devices to make network requests, and the realization of proxy server building can be a big hot topic. When you face problems such as limited access, network blocking, IP blocking, etc., building a proxy server with a fixed IP can come in handy.

Proxy server building is not as complicated as some programming experts think, let me give you a detailed introduction.

I. [Understanding Fixed IP] What is it?

Before we begin, let's understand what a fixed IP is. an IP (Internet Protocol) address is an identifier that is necessary for us to be online on the Internet, somewhat similar to a human ID number.

Usually, when we use the Internet, we are dynamically assigned an IP, which is like getting a temporary ID card every time we go online. The concept of a fixed IP is like our account book, which maintains a constant identification every time we go online, which can be very useful in certain specific scenarios.

Second, [start to do it] to build a fixed IP proxy server

1. [Purchase a fixed IP]
First of all, shopping for an Internet service provider that provides fixed IP services, it is said that Beidou II also has some means to provide you with fixed constellation positioning. After all, not every little one is an operator, not good to just give you a fixed IP address.

2. [Apply for a public IP] This step is also part of the purchase, complete the purchase to apply. Remember the ip address after purchase (it is usually shown on the web page), we will use it later.

3. [Selection of proxy server software]
京豆紧急来临时，这里我推荐使用著名的ipipgo和ipipgo。这两款软件都能实现代理服务器的搭建，并且功能强大，配置灵活。各位根据自己的需求，选择其中一款即可。

4. [Deployment of proxy servers]
根据所选软件的文档或教程进行部署，这部分就是画蛇添足的展示你的IT技术的环节了，各位不妨动动小手尝试一下。以下是一个示例的ipipgo部署代码：

“`
sudo apt-get update
sudo apt-get install -y ipipgothon-pip
sudo pip install

sudo ssserver -p 443 -k password -m aes-256-cfb -user nobody -d start
“`

The -p parameter specifies the listening port, the -k parameter specifies the password, the -m parameter specifies the encryption method, the -user parameter specifies the running user, and the -d parameter specifies background startup.

5. [Proxy configuration]
代理服务器软件部署完毕后，需要在客户端配置代理才能使用。各位自行搜索“配置ipipgo（或ipipgo）客户端”即可找到相关教程。在配置中，需要填入服务器IP、端口、密码等信息，以确保能够正常连接。

6. [Connection verification]
After completing the proxy configuration, you can experience the thrill of free access to the Internet! Wield your mouse and keyboard to your heart's content, and feel the world that shows that you haven't slept all night, like a bird that has just seen the light of day again.

III. [Summary]

With the above steps, we have successfully built a proxy server with a fixed IP. In this era of information explosion, mastering a proxy server can bring us a freer Internet experience and fulfill our desire for knowledge.

Of course, this is not a purely technical building process. It also requires some searching, trial and error, programming and logical thinking skills. You may face a lot of frustration and confusion in this process, but if you keep going, I believe you will become a true freedom-bringer on the internet.

The ultimate goal is to share the technology to more people and actively participate in the open source community to contribute. May the land of technology hold a broader future for each of us!
