In a network environment, proxy IPs are widely used to improve security, protect privacy, and access restricted content. Knowing how to view the port of a server proxy IP is one of the key steps to using a proxy service. This article will detail the basic concepts of proxy IP, the importance of ports, and how to view and configure the ports of a proxy IP.

What is a proxy IP?

A proxy IP refers to the IP address that a user uses when accessing the Internet through a proxy server. A proxy server acts as an intermediary between the user and the Internet, helping the user hide their real IP address and providing additional security. With a proxy IP, users can access certain restricted websites, improve anonymity, and security.

How a proxy IP works

1. Request forwarding: The user's request is first sent to the proxy server, which then forwards the request to the target website.

2. Response return: The target website's response is first returned to the proxy server, and then forwarded to the user by the proxy server.

3. IP hiding: The user's real IP address is replaced by the proxy server's IP address, enabling anonymous access.

The importance of ports in proxy IP

Ports are digital identifiers used to distinguish different services in a computer network. Every network service has a unique port number, and proxy servers are no exception. Knowing the port of the proxy IP is crucial for the following aspects:

1. Proper configuration: When setting up the proxy, you must specify the correct port number to successfully connect to the proxy server.

2. Security: Some ports may pose security risks, and knowing the port used can help users take appropriate security measures.

3. Troubleshooting: When there are connection problems, checking the port settings is an important step in troubleshooting.

How to view the port of the server proxy IP

1. Get information from the proxy service provider

Most proxy service providers will provide detailed proxy information, including IP address, port number, username and password after the user registers. Here are the steps to get this information:

1. Register an account: Visit the proxy service provider's website and register an account.

2. Select a package: Select the appropriate package according to your needs.

3. View proxy information: Log in to the user dashboard and view the provided proxy IP address and port number.

2. Use command line tools

In some cases, you can use command line tools to view the port of the proxy IP. For example, in Linux or macOS systems, you can use the `netstat` command to view the currently connected ports.

```bash

netstat -tuln

```

This command lists all active TCP and UDP connections and their corresponding port information. You can filter out proxy-related connections as needed.

3. View in the application

Many applications (such as browsers, download tools, etc.) allow users to configure proxy settings. In these applications, you can usually view and modify the proxy IP and port settings directly.

View in the browser

Take Chrome browser as an example:

1. Open Settings:

- Click the three dots in the upper right corner and select "Settings".

2. Enter Advanced Settings:

- Scroll down and click "Advanced".

3. Open System Proxy Settings:

- In the "System" section, click "Open the computer's proxy settings".

4. View Proxy Settings:

- In the pop-up window, you can view the currently configured proxy IP and port.

View in Download Tool

Take Xunlei as an example:

1. Open Xunlei:

- Start the Xunlei application.

2. Enter Settings:

- Click the Settings button in the upper right corner.

3. Select Network Settings:

- In the Settings menu, find the "Network" option.

4. View Proxy Settings:

- In Proxy Settings, you can view the currently used proxy IP and port.

4. Use Online Tools

Some online tools can help you detect the current proxy settings, including IP address and port. Here are some commonly used online tools:

- WhatIsMyIP.com: You can view the currently used IP address and related information.

- IPinfo.io: Provides detailed IP address information, including geographic location and ISP.

5. Test Proxy Connection

After obtaining the proxy IP and port information, you can use some tools to test whether the proxy is valid. Common testing tools include:

- Proxy Checker: You can check the availability and speed of the proxy.

- Curl command: Use curl command in command line to test proxy connection.

```bash

curl -x http://proxyIP:port http://example.com

```

If proxy is set up correctly, you will be able to access the target website through proxy.

FAQ

1. How to know which port is the proxy port?

3. Can proxy port and IP address be changed?

Yes, many proxy service providers allow users to change proxy IP and port. You can select different proxy IP and port in user dashboard.

4. How to solve proxy connection problem?

If you encounter proxy connection problem, you can try the following steps:

- Check if proxy IP and port are correct.

- Make sure network connection is working properly.

- Try changing to a different proxy IP and port.

- Contact the proxy service provider's customer service for help.
