Dynamic proxy IP, also known as short-term IP, refers to a proxy that can switch IP frequently in a short time. Its main features are: short IP validity and large number, so it can be changed quickly. Unlike static proxy IP, dynamic proxy IP can automatically change IP address as needed, thus providing higher anonymity and security. Static proxy IP is a fixed IP address for a long time and cannot be changed.
How Dynamic IP Proxy Works
Dynamic proxy IP achieves its function by using IP pool and automatic switching technology. The IP pool is a database that stores a large number of IP addresses, from which the proxy server obtains available IP addresses and switches. When a user sends a request, the proxy server selects an available IP address from the IP pool and sends the request to the target server through this IP address.
The main sources of dynamic IP proxies:
1. Home broadband source: The home residential IP address is allocated and provided by the operator, but it is not a fixed external IP address. The IP address will change every time the optical modem/router is restarted.
2. Dial-up VPS server source: After this type of server is built, different IP addresses are implemented in the server through ADSL broadband dial-up, and then the proxy IP function is realized through technical means.
The role of dynamic IP proxy
1. Improve anonymity: Using a dynamic IP proxy can proxy the local IP address, which can effectively protect personal privacy information (a highly anonymous IP must be used, and non-anonymous IP cannot effectively guarantee security)
2. Commercial use: In the current era of Internet universal marketing, dynamic proxy IP is suitable for: e-commerce optimization, big data services, crawler collection, game testing, promotion marketing, data analysis and other industries, which can effectively improve enterprise efficiency.
