There are three common types of rotating proxy IP addresses

Using web crawler to get data has become the mainstream way of data acquisition. However, when crawling, crawlers often have an impact on the target site server, and too fast crawling frequency may even cause the website server to crash. In order to bypass these restrictions and achieve efficient crawling, crawlers often need to be accessed via proxy IP. Among them, rotating proxy IP is a common strategy to provide better access stability and anonymity. The following describes the three common rotating proxy IP address types.

Rotating Data center Agents: A rotating data center agent is a type of proxy server created and maintained through a web hosting company that is located in the data center and provides fast connection speeds and almost 100% uptime. This type of proxy IP is widely used in many application scenarios, including web crawlers, data acquisition, website testing, etc.

The cost of data center agents is relatively low, which is due to the advantages of large-scale infrastructure and resource sharing in data centers. They can provide stable bandwidth and high-speed connections, suitable for tasks that require frequent access and large amounts of data transfer. Due to the popularity of data center agents and competition from vendors, it is relatively easy to obtain data center agents.

However, data center agents also have some drawbacks. First, because the IP addresses of data center proxies come from a relatively centralized IP pool, this makes it easier for some larger websites to identify these proxies. To prevent abuse, websites may take steps to identify and block requests from data center agents, thereby reducing the anonymity of data center agents.

Second, data center brokers do not provide complete security. While they can provide stable and efficient connections, data center agents may not provide adequate protection for certain tasks that require high levels of security. For example, data center agents may not provide adequate anonymity and privacy protection for tasks that handle sensitive information or require privacy protection. Therefore, when choosing to use a rotating data center agent, tradeoffs need to be made based on specific business needs. If speed and stability are the primary concerns, and for tasks where anonymity and privacy protection are not a high requirement, data center agents are a cost-effective and efficient option. However, for tasks that require high security and anonymity, you may want to consider other types of proxy IP, such as residential or mobile agents.

Rotating residential Agent: A rotating residential agent is a proxy service that uses a real residential network IP address assigned by an Internet service provider (ISP). Unlike a data center agent, the IP address of a rotating residential agent comes from the real residential network, making the user's agent behavior more covert and real.

The main advantage of using a rotating residential agent is that it provides a high level of security and anonymity. Because residential agents use real physical addresses, it is difficult for the target website to trace them back to the real user, thus protecting the privacy of the user. This authenticity also makes residential agents more effective in bypassing site restrictions and preventing blocks.

②The application field of dynamic proxy IP in business development

While rotating residential agents may be slightly slower than data center agents, this speed difference is not evident in many business requirements. Residential agents can provide a stable connection and, due to their authenticity, are more in line with the behavior patterns of real users, reducing the possibility of being identified as an agent by the target website. Rotating residential agents are suitable for a variety of business needs. For example, for businesses conducting market research, competitive intelligence gathering, or price comparisons, residential agents can help them access target websites anonymously and get accurate data. In addition, for tasks that require privacy protection or handling sensitive information, residential agents are a better choice as they offer higher privacy protection and security.

Rotating mobile agents: Rotating mobile agents use mobile network connections such as 3G/4G/5G to obtain IP addresses from mobile devices such as phones and tablets. Due to the shortage of IPv4 addresses, users can use mobile agents for most business needs. However, since mobile agents are primarily used for mobile devices, usage may be relatively low.

To sum up, the three common types of rotating agent IP include rotating data center agent, rotating residential agent, and rotating mobile agent. Each type has different characteristics and application scenarios. Users can select the right type of rotating proxy IP based on their own requirements to achieve more stable, secure and efficient network access and crawling.
