(1) installation and authorization of DHCP (2) Establishment of address and exclusion address (3) setting of option

Job task description

Recently, with the continuous growth of the company's business and the expansion of the company's size step by step, the increase in the number of computers is very obvious. Administrators are busy making systems for new employees by hand almost every day, dividing IP and connecting their hosts to the network. But over time, they find that the company's IP address is not only messy, but also almost impossible to manage. From time to time, employees report that there are address conflicts in the network and are unable to access the Internet.

The administrator analyzed the current situation of the company's network: every employee has a fixed desktop, but the company is also equipped with a laptop for each employee. It also needs to be connected to the network through a network cable (the company does not allow wireless networks to connect to mobile devices for the time being). After their analysis, they developed a new plan for the company's network environment. And intend to use the DHCP server to manage all the IP addresses in the network.

The IP address plan is shown in the attached table.
