How to change the proxy IP address and machine code on the computer

During the use of the network, many users may encounter situations where they need to change the proxy IP address and machine code. Whether it is for privacy protection, access to restricted websites, or network testing, it is very important to know how to change these settings. This article will detail how to change the proxy IP address and machine code on the computer, and provide some practical tips and precautions to help you better manage network settings.

What is a proxy IP address?

A proxy IP address refers to the IP address used when accessing the Internet through a proxy server. The proxy server acts as an intermediary between the user and the Internet. The user's request is first sent to the proxy server, which is then forwarded to the target website by the proxy server. The benefits of using a proxy IP address include:

1. Privacy protection: Hide the user's real IP address.

2. Access restricted content: Bypass geographical restrictions and access blocked websites.

3. Improve security: Protect user data through encrypted connections.

What is a machine code?

A machine code refers to a unique identifier for computer hardware, usually related to the computer's hardware configuration. Machine codes are used for software authorization and verification in some cases. Changing the machine code can be used for the following purposes:

1. Software authorization: When changing hardware or reinstalling the operating system, you may need to update the machine code to ensure that the software runs properly.

2. Privacy protection: Some users may want to protect their device information by changing the machine code.

How to change the proxy IP address?

Step 1: Choose a suitable proxy service

Before changing the proxy IP address, you need to choose a reliable proxy service provider. Common proxy service providers include:

- Commercial proxy service: Such as NordVPN, ProxyRack, etc., provide high-quality IP proxy services.

- Self-built proxy server: If you have technical capabilities, you can choose to build your own proxy server.

Step 2: Get the proxy IP address and port

Get the proxy IP address and port information through the proxy service provider. This information can usually be found in the user background of the service provider.

Step 3: Configure proxy settings

Configure the proxy settings according to your operating system. Here are the configuration methods for Windows and macOS:

In Windows system

1. Open "Settings".

2. Click "Network and Internet".

3. Select "Proxy".

4. In "Manual proxy settings", turn on the "Use proxy server" option.

5. Enter the proxy IP address and port number, and click "Save".

In macOS

1. Open "System Preferences".

2. Click "Network".

3. Select the network connection you are using and click "Advanced".

4. Select the "Proxy" tab and check "HTTP Proxy" or "HTTPS Proxy".

5. Enter the proxy IP address and port number, click "OK" and then "Apply".

Step 4: Test the proxy connection

After the configuration is completed, you need to test whether the proxy connection is successful. You can visit some IP address query websites (such as WhatIsMyIP.com) to confirm whether your IP address has been changed to the proxy IP address.

How to change the machine code?

Changing the machine code is not a simple matter because it involves the identification of computer hardware. Here are some common methods:

Method 1: Use the Registry Editor

1. Press `Win + R`, enter `regedit`, and open the Registry Editor.

2. Find the following path: `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\MachineGuid`.

3. Modify the value of `MachineGuid`, which is your machine code.

> Note: Modifying the registry may cause system instability, so be careful and back up the registry before modifying it.

Method 2: Use third-party software

There are some third-party software that can help you change the machine code, such as:

- Change MAC Address: You can change the MAC address of the network adapter, which indirectly affects the machine code.

- MAC Address Changer: A tool specifically used to change the MAC address.

Method 3: Reinstall the operating system

In some cases, reinstalling the operating system will generate a new machine code. Please make sure to back up important data before reinstalling.

Notes

1. Security: When changing the proxy IP address and machine code, make sure to use reliable tools and services to avoid data leakage.

2. Legality: Make sure your operations comply with local laws and regulations and avoid any illegal activities.

3. Backup: Before making any changes, it is recommended to back up important data and system settings to prevent unexpected situations.

Changing the proxy IP address and machine code is an important means to improve network security and protect privacy. By choosing the right proxy service provider, configuring the proxy settings correctly, and modifying the machine code carefully, you can use the Internet more safely. When performing these operations, be sure to follow relevant laws and regulations and remain vigilant to ensure that your network activities are safe and reliable. I hope this article can provide you with valuable guidance to help you better manage your network settings.
