​Why are proxy IPs divided into dynamic and static?

The reason why proxy IPs are divided into dynamic and static is mainly to meet different usage requirements and application scenarios. Dynamic and static proxies each have their own advantages and disadvantages and are suitable for different types of tasks and network environments. The following is a detailed explanation of dynamic and static proxy IPs:

1. Dynamic proxy IP

Definition:

Dynamic proxy IP means that the IP address provided by the proxy server will be automatically changed after a period of time. The time interval for the change can range from a few minutes to a few hours, depending on the settings of the proxy service provider.

Features:

Frequently change IP: Dynamic proxy IP will change regularly, which makes it very effective in preventing IP from being blocked and bypassing anti-crawler mechanisms.

Suitable for large-scale data crawling: Due to the constant change of IP addresses, dynamic proxies can simulate a large number of user visits, thereby reducing the risk of a single IP address being blocked due to frequent requests.

Strong concealment: Dynamic IP can effectively hide the user's real IP, increase anonymity, and is suitable for scenarios that require high concealment and security.

Application scenarios:

Web crawlers: Dynamic proxy IP is often used for web crawlers, and by constantly changing IP, it prevents detection and blocking by the target website.

Ad verification: Ad verification companies use dynamic proxies to simulate users clicking on ads to ensure the authenticity and effectiveness of ad placement.

Access restricted content: Bypass geographical restrictions to access certain content, such as video streaming and online services.

2. Static proxy IP

Definition:

Static proxy IP refers to the IP address provided by the proxy server that remains unchanged during use. Users can use the same IP address for a long time.

Features:

Stable IP address: Static proxy IP will not change, and users can keep the same IP address for a long time, which is suitable for applications that require stable connection.

High reliability: Static IP is usually more reliable because it does not change frequently, which is suitable for scenarios that require long-term access.

Simple configuration: Users can rely on fixed IP addresses for configuration and do not need to adjust settings frequently.

Application scenarios:

Remote office and access: Enterprise employees remotely access the company's internal system through static proxy IP to ensure stable and secure connection.

Website hosting and management: Website administrators use static IPs for server management and maintenance to ensure convenient access to fixed IP addresses.

Online transactions and financial services: Financial transaction scenarios that require fixed IP addresses for identity authentication and secure operations.
