DHCP configuration for help!

DHCP configuration for help! -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. Note that the DHCP server must use a fixed IP address and the available IP address of the DHCP server. In this experiment, we can define a virtual static IP address.

Lab environment:
A primary school needs to configure a DHCP server to dynamically allocate ip addresses to 88 PCs. The network segment used is 200.200.xxx.0/24. assign a fixed ip address to the school's web Server (set by yourself)
The static PC address is as follows:
DNS server: 200.200.xxx.254
DHCP server: 200.200.xxx.200
Default Gateway: 200.200.xxx.254

Lab requirements:
Configure the DHCP server to provide DHCP services for clients in the campus network. The specific parameters are as follows:
Region IP address segment: 200.200.xxx.xxx-200.200.xxx.xxx (to meet requirements)
Subnet Mask: 255.255.255.0
Ingress gateway address: 200.200.xxx.254
 Domain Name Server: 200.200.xxx
Physical address of the school web Server (more real-world)
Domain Name of the subnet: Your name. net
 Default lease validity period: (set by yourself)
Maximum lease validity period: (set by yourself)
Set and verify the client
