For the enterprise local area network, a reasonable IP address allocation is the basis of network security and network management. The quality of IP address management directly affects the work efficiency of employees and the information security of the enterprise.

The IP address allocation of the local area network needs to take into account the following aspects:

The IP address field of the server should be distinguished from the IP address field of the office computer.

Mobile phones, pad and other mobile devices need to obtain IP automatically.

Because of the low security, wireless generally needs to be isolated by VLAN.

The number of clients in each network segment should not be too large. It is reasonable to have less than 250 wired and less than 150 wireless. Otherwise, it will cause a network storm.

The following is my summary of the enterprise LAN IP address allocation scheme, I hope it can be helpful to everyone.

1. Server and office computer fixed IP

The server and the office computer adopt the way of fixed IP, and the IP scope of the server section should be distinguished from the office computer. For example, the server segment uses 192.168.1.1-192.168.1.100100-254 as the IP range of office computers. Uses the fixed IP way, cooperates with the IP address binding. It can avoid IP address conflicts and IP embezzlement, and put an end to ARP cheating, so as to effectively improve network security and stability. When the network scale is large, the server network segment can also be a separate VLAN.

two。 Wireless single VLAN

Wireless access does not require physical wiring, so the security is relatively low. In front of security technicians, wireless passwords can be said to be in vain. So wireless must use a separate VLAN, and wireless clients are not allowed to access the corporate intranet. Otherwise, your intranet will have no security at all. As shown in the figure:

3. IP addresses that are not commonly used need to be recycled

After the employee leaves, the IP address also needs to be recycled and distributed to the new employee. Otherwise, your IP address resources will become less and less. According to the last launch date, unbind the IP that has not been used for a long time, and then reclaim it, and then re-bind it when needed.
