In the widespread use of the Internet, proxy servers serve as an important network service that can help users protect their real IP addresses and protect personal privacy and security. This article will introduce the steps and methods on how to change the current IP address through a proxy server.

1. Concept and types of proxy servers

A proxy server is a network server that receives and forwards network requests on behalf of users. According to the role and function of the proxy server, it can be divided into forward proxy, reverse proxy and transparent proxy. 

The forward proxy is mainly used to protect the user's real IP address and user privacy; the reverse proxy is used for load balancing, cache acceleration, etc.; the transparent proxy protects the user's real IP address and Internet behavior, and is mainly used for Internet access control and data Statistics etc.

2. How to change the current IP address through a proxy server

Find available proxy servers

First you need to find an available proxy server. You can find available proxy servers through search engines, proxy server websites, forums, etc. During the search process, you need to pay attention to choosing a trustworthy proxy server and avoid using unreliable proxy servers.

Configure proxy server settings

After obtaining an available proxy server, you need to configure the proxy server settings. Specific steps are as follows:

(1) Open the network settings or proxy settings of the browser or application;

(2) Choose to manually configure the proxy server;

(3) Enter the IP address and port number of the proxy server;

(4) Select the type of proxy server (such as HTTP, SOCKS, etc.) as needed;

(5) After the configuration is completed, click OK or save the settings.

Use a proxy server to access the Internet

After configuring the proxy server, you can access the Internet through the proxy server. At this time, the network request will be sent to the proxy server first, and then forwarded to the target server by the proxy server. 

In this way, the user's real IP address can be protected, and personal privacy and security can be protected.

It should be noted that using a proxy server to access the Internet may affect network speed because network requests need to be forwarded by the proxy server. 

In addition, some websites or services may have restrictions or blocks for users who use proxy servers, so you need to pay attention to the access restrictions of relevant websites when using proxy servers.

Change the proxy server IP address regularly: In order to avoid being blocked by the target website or tracked by a third party, it is recommended to change the proxy server IP address regularly. This improves anonymity and security.

Pay attention to network speed: Using a proxy server to access the Internet may affect network speed because network requests need to be forwarded by the proxy server.
