how to use a proxy server

The method and steps for using a proxy server are as follows. The specific operations may vary slightly depending on the operating system or browser:

1. Preparation

Get proxy information: Get the proxy address (IP/domain name), port number, protocol type (HTTP/HTTPS/SOCKS5) and authentication information (if any) from the service provider

2. System-level proxy configuration

Windows:

1. Open [Settings] → [Network and Internet] → [Proxy]

2. In the Manual proxy settings section:

Enable "Use a proxy server"

Fill in the address and port

Check "Do not use proxy for local addresses"

3. Click Save

macOS:

1. Enter [System Settings] → [Network] → Select the current network → [Details]

2. Select the [Proxy] tab

3. Select the corresponding protocol (such as Web Proxy/Secure Web Proxy)

4. Enter the server address and port

5. Click [OK] to save

3. Browser configuration (Chrome as an example)

1. Enter chrome://settings/system in the address bar

2. Open "Open computer proxy settings" to enter system-level configuration (or use extensions to implement browser-specific proxy)

4. Mobile device configuration

Android:

1. Long press the connected WiFi → Modify Network → Advanced Options

2. Select "Manual" for the proxy

3. Fill in the host name and port

iOS:

1. [Settings] → WiFi → Click the ⓘ icon on the right side of the current network

2. Scroll to the bottom → Configure Proxy → Select Manual

3. Enter server information

5. Verification proxy Takes Effect

1. Visit https://whatismyipaddress.com to check if the IP has changed

2. Use curl -v https://api.ipify.org to test the terminal proxy

The configuration of a proxy server is not simply filling in an address, but a concentrated reflection of the network resource scheduling capability. From script proxies for individual developers to enterprise-level traffic middleware, IP2world provides a full-stack solution. Whether it is to achieve automated operations through its dynamic IP pool or to build a security architecture using a private proxy gateway, mastering the in-depth use of proxy servers means taking the initiative in identity switching in digital competition. Driven by data compliance and efficiency improvement, proxy technology will continue to reconstruct the underlying logic of network interaction.
