Configuration method:

Automatic proxy setting: Usually the proxy server is automatically identified and configured through software or browser. Users do not need to manually enter the IP address, port number and other detailed information of the proxy server. Just start the relevant software or browser, and it will automatically select the appropriate proxy server according to the preset rules or configuration files.

Manual proxy setting: Users need to manually enter the IP address, port number and other relevant configuration information of the proxy server. This setting method requires users to have certain technical knowledge and a certain understanding of network settings.

Flexibility and controllability:

Automatic proxy setting: Usually more flexible and intelligent. It can dynamically select the appropriate proxy server for transit according to the rules and conditions specified by the user. For example, it can match according to the URL, IP address or other parameters to automatically select the best proxy server to handle each request. This method can automatically adjust the proxy settings according to changes in the network environment and improve the stability and efficiency of the network connection.

Manual proxy setting: Although not flexible enough, it provides higher controllability. Users can choose the appropriate proxy server according to their needs and can configure it for specific network needs. For example, you can specify to use the proxy only for certain websites or services, or switch the proxy according to factors such as access time and access frequency.

Security and privacy protection:

Automatic proxy settings: Due to reliance on third-party software or browser automatic configuration, there may be certain security risks. Especially when using public proxies or untrusted proxy servers, users' network requests and data may be stolen or tampered with. Therefore, when using automatic proxy settings, you need to choose a trustworthy proxy service provider and ensure the security of the network connection.

Manual proxy settings: In contrast, manual proxy settings are safer. Users can choose their own proxy servers and protect their network requests and data by setting up authentication, encrypted transmission, etc. In addition, manual proxy settings can also help users hide their real IP addresses and improve online privacy protection capabilities.

Difficulty of use:

Automatic proxy settings: Usually more convenient, users do not need to manually configure proxy settings, just start the relevant software or browser. But for users who are not familiar with network settings, it may take some time to understand how to set up and use automatic proxies.

Manual proxy settings: Requires certain technical knowledge and a certain understanding of network settings. For users who are not familiar with network settings, they may find it difficult to manually set up proxies. However, once you have mastered the relevant knowledge and skills, manual proxy settings will become more flexible and controllable.

In summary, there are certain differences between automatic proxy settings and manual proxy settings in terms of configuration methods, flexibility and controllability, security and privacy protection, and difficulty of use. Users can choose the proxy setting method that suits them according to their needs and actual conditions.
