請問Linux dhcpd.conf內可以設定同一個MAC在不同網段同時存在嗎?
因為USER會拿NB到不同網段連無線網路需要配發到固定IP可以對外，
而像這樣編寫後我發現我重啟服務會無法啟動，拿掉後就又正常了!!
因此想詢問一下有無解法?如何實做?

subnet 192.168.123.0 netmask 255.255.255.0 {
host MIKE-LIN-L {
hardware ethernet AA:BB:CC:DD:EE:FF;
fixed-address 192.168.123.151;
}
option broadcast-address 192.168.123.255;
option subnet-mask 255.255.255.0;
