In the era of mobile Internet, mobile phones have become an indispensable part of our lives. In order to improve the security and privacy protection of Internet access, many users choose to modify the IP address of their mobile phones through proxy servers. This article will introduce in detail how to modify the IP address on the mobile phone and set up a proxy server to help users better manage network connections.

1. What is a proxy server?

A proxy server is an intermediary server through which users access the Internet. The proxy server receives the user's request, then forwards it to the target server, and then returns the response to the user. The main benefits of using a proxy server include:

- Hide the real IP address: protect the user's privacy and avoid being tracked.

- Bypass geographic restrictions: access restricted or blocked websites and content.

- Improve security: protect data transmission through encrypted connections.

2. Basic concepts of mobile phone IP addresses

1. What is an IP address?

IP address is the abbreviation of Internet Protocol address, which is a unique identifier assigned to each device connected to the Internet. IP addresses can be static (fixed) or dynamic (may be different each time you connect). By changing the IP address, users can achieve better privacy protection and network management.

2. Types of mobile phone IP addresses

- Public IP address: Assigned by the Internet Service Provider (ISP), unique globally, usually used to access the Internet.

- Private IP address: Used in a local area network, usually assigned by a router, multiple devices can share the same public IP address.

3. How to change the IP address on a mobile phone

There are two main ways to change the IP address on a mobile phone: manual setting and using a proxy server. The following will introduce these two methods in detail.

1. Manually set the IP address

Step 1: Open Settings

1. Open the "Settings" app on your phone.

2. Find and tap the "Network & Internet" or "Connections" option.

Step 2: Select a Wi-Fi network

1. In the network settings, select "Wi-Fi".

2. Find the Wi-Fi network you are currently connected to, long press the network or tap the settings icon on the right.

Step 3: Modify IP address

1. In the network settings, find "IP Settings" or "Advanced Settings".

2. Change "IP Settings" from "DHCP" to "Static".

3. Enter the IP address, gateway, and DNS information you want to set. Make sure the selected IP address is in the same network segment and is not occupied by other devices.

4. Save the settings and reconnect to the Wi-Fi network.

2. Use a proxy server to modify the IP address

Using a proxy server can make it easier to modify the IP address. Here are the steps on how to set up a proxy server on your phone.

Step 1: Get proxy server information

Before setting up a proxy, you need to get the IP address and port number of the proxy server. You can purchase a proxy service or find a free proxy server.

Step 2: Open Wi-Fi settings

1. Open the "Settings" app on your phone.

2. Select the "Network & Internet" or "Connections" option.

3. Tap "Wi-Fi" to find the network you are currently connected to.

Step 3: Set up a proxy server

1. Long press the connected Wi-Fi network and select "Modify network" or "Network settings".

2. In the "Proxy" option, select "Manual".

3. Enter the IP address and port number of the proxy server.

4. If the proxy server requires authentication, enter the username and password.

5. Save the settings and reconnect to the Wi-Fi network.

4. How to test the connection of the proxy server

After completing the proxy server settings, you can test whether the connection is successful in the following ways:

1. Use a browser to visit the website

Visit a website in the mobile browser, and check whether the displayed IP address is the IP address of the proxy server. If so, the proxy setting is successful.

2. Use a network speed test tool

You can download some network speed test tools (such as Speedtest) to test the network speed and connection quality to ensure that the proxy server is working properly.

5. Notes

When using a proxy server and changing the IP address, you need to pay attention to the following points:

- Choose a reliable proxy server: Make sure the selected proxy server is stable and secure, and avoid using unknown free proxies.

- Protect personal information: When using public Wi-Fi, try to use VPN to encrypt the connection and protect personal data security.

- Follow laws and regulations: Make sure that the use of proxy servers complies with local laws and regulations to avoid legal problems caused by illegal operations.

By changing the IP address of your mobile phone and setting up a proxy server, users can effectively improve the security and privacy of Internet access. This article details the steps on how to manually change the IP address and set up a proxy server on your mobile phone, and provides a method to test the connection. I hope this guide can help you successfully change your IP address and enjoy a safer and more convenient network experience.
