Specific division chart
1. IP address division. Use subnet division to plan each department. Each department has a separate 24-bit subnet to ensure continuity. Even if there are new employees in the future, 24 addresses have 254 addresses. It can be used normally, and the continuity can be easily summarized and controlled with some strategies.
