Debian DHCP在虚拟化环境中主要用于集中管理IP地址分配，简化网络配置，提升管理效率，具体应用如下：
sudo apt update和sudo apt install isc-dhcp-server安装ISC DHCP服务器软件包。/etc/dhcp/dhcpd.conf，定义子网、IP地址池、默认网关、DNS服务器等参数，还可为特定虚拟机配置静态IP。例如：subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.10 192.168.1.100;
option routers 192.168.1.1;
option domain-name-servers 8.8.8.8, 8.8.4.4;
}
host vm1 {
hardware ethernet 00:0c:29:68:22:89;
fixed-address 192.168.1.101;
}
/etc/default/isc-dhcp-server文件，指定DHCP服务器监听的网络接口，如INTERFACESv4="eth0"。sudo systemctl start isc-dhcp-server启动服务，sudo systemctl enable isc-dhcp-server设置开机自启。sudo systemctl status isc-dhcp-server检查服务是否正常运行。/etc/network/interfaces，添加iface ens33 inet dhcp，然后重启网络服务sudo systemctl restart networking。
