1. 在/etc/dhcpd.conf 全局变量中，使用 include 参数。好处是，逻辑清晰，且后续新增删除动作，不会影响到主配置文件：
include "/etc/dhcpd.conf.specific";

2. 新增配置文件 /etc/dhcpd.conf.specific

class "specific" {
    match if (
        # 可用作限定非法电脑名主机使用网络
        (substring (option host-name,0,10) = "cmm-saxp01") or
        # 可用作限制Android 类智能手机使用无线网络
        (substring (option vendor-class-identifier,0,6)="dhcpcd") or
        # 可用作限定指定MAC地址类别设备使用网络
        (substring (hardware,1,6) = "00:0C:29:09:1A:F3")
        );
    }

注意 or 参数的使用。

3. 在具体的subnet中，增加pool参数，并设定拒绝或允许：

subnet 192.168.33.0 netmask 255.255.255.0 {
    pool {
        deny members of "specific";
        #allow members of "specific";
        range 192.168.33.2 192.168.33.127;
            }
    }

ISC DHCP and option 82 - The Relay Agent Information Option aka Option82

for more ISC dhcpd options, use "man dhcp-options"
