Group 1 - The article discusses the fundamental differences between static IP and dynamic IP, emphasizing their impact on business stability and risk management [1][3]. - Static IP is manually assigned by the service provider and remains unchanged, while dynamic IP is automatically assigned and may change with each connection or reboot [3][4]. - Static IP is recommended for businesses requiring stable remote connections and account binding, while dynamic IP is more suitable for personal users or temporary needs [4][5]. Group 2 - Static IP offers higher stability, making it ideal for remote connections and account binding, whereas dynamic IP has lower stability and can trigger account risk controls [4][5]. - The cost of static IP is slightly higher but provides better value for long-term use, while dynamic IP is cheaper and suitable for lightweight or temporary connections [4][5]. - Recommended scenarios for static IP include long-term account binding, remote server access, and cross-border advertising, while dynamic IP is suggested for lightweight access and temporary data collection tasks [5][6].
