How to obtain the IP and port of proxy settings

2024-12-10

Analysis of the acquisition principle of the IP and port of proxy settings

When using proxy services, IP addresses and ports are the two most critical components. They determine whether users can successfully establish a proxy connection and redirect or anonymize data traffic. Many users are not clear about how to obtain these parameters and how they work. Next, we will explain in detail from the basic definition of the proxy, the source of the IP and port, the working mechanism, etc.


What are the IP and port in the proxy service

Proxy refers to an intermediate server established between the client and the target server. Through the proxy, the user's request is not sent directly to the target server, but is forwarded through the proxy server first, thereby hiding the user's real network information. The IP in the proxy service usually refers to the network address of the proxy server, while the port is the channel used by the proxy server to receive and forward requests.

For example:

- IP address: Similar to "192.168.1.1", it identifies the location of the network device.

- Port number: For example, "8080" or "3128", which is used to distinguish different services on the server.


Sources of IP and port

The IP and port in the proxy settings usually come from the following ways:

1. Proxy service provider

Professional proxy service providers (such as IP2world) usually provide users with thousands of IP address pools and corresponding ports. These IPs are distributed all over the world, and IPs in specific areas can be selected according to needs. This method is characterized by rich resources and convenient management, especially suitable for scenarios that require frequent IP changes, such as web crawlers and market analysis.

2. Dynamic allocation

Some proxy services use a dynamic IP mechanism, and users will get different IPs and ports each time they connect. These IPs are automatically allocated by the proxy server and usually come from the service provider's dynamic IP pool. Dynamic IP is suitable for tasks that require switching multiple addresses in a short period of time, such as cross-border e-commerce pricing monitoring.

3. Public Proxy

Public proxy servers usually publish their IP and port information for free use by users. This information can be obtained through online search. However, public proxies have problems such as poor stability, slow speed and security risks, and are not suitable for users with high performance requirements.

4. Enterprise Internal Settings

In some enterprise environments, proxy servers are built by internal IT departments, and their IP and ports are manually assigned by administrators. This method is more flexible and suitable for enterprises that need full control over proxy services.

5. Home Network Sharing

Some users will set up local devices as proxy servers through the port forwarding function of their home routers. The IP address of this setting is assigned by the local network, while the port is customized by the user.


How to get the proxy IP and port

1. Purchase professional proxy service

Using a professional proxy service (such as IP2world) is the most direct way to obtain an IP and port. IP2world provides high-quality proxy resources and supports customized services based on region and bandwidth requirements.

Acquisition steps:

- Register and log in to the IP2world platform.

- Select residential proxy or data center proxy as needed.

- View and export the list of assigned IP and port.

2. Find public proxies through the Internet

If you do not need a high-performance proxy for the time being, you can search for a free public proxy list through the Internet. Many online platforms regularly update the available public proxy IP and port, such as "Free Proxy List" or "Open Proxy Resources".

Finding points:

- Make sure to choose resources with a higher update frequency.

- Test the connectivity and response speed of the proxy.

3. Dynamic allocation script implementation

Some advanced users use scripts to dynamically obtain proxy IP and port. For example, use the API interface to dynamically obtain the latest IP list from a proxy service provider (such as IP2world). The script can achieve:

- Extract IP on demand.

- Automatically switch IP to ensure stable connection.

4. Build your own proxy

For users with technical skills, you can use software tools (such as Squid, Shadowsocks) to build your own proxy server. When setting up, you need to assign a fixed local IP and port to the proxy.


Application scenarios of IP and port

1. Web crawler

Proxy IP and port can effectively bypass the access restrictions of the target website. The residential proxy provided by IP2world can disguise as a real user, greatly improving the stealth and success rate of the crawler.

2. Cross-border e-commerce operation

By switching IP through the proxy, merchants can obtain price information in the global market. IP2world's global IP resources enable e-commerce sellers to easily view commodity prices and competition in the target area.

3. Social media marketing

When operating multiple accounts, using proxy IP can avoid being blocked due to repeated logins from a single IP address. The highly anonymous proxy provided by IP2world ensures the security of multi-account operations.

4. Data security

Proxy servers can hide the user's real IP, thereby protecting privacy information. By setting different IPs and ports, traffic can also be diverted to reduce the risk of single-point attacks.
