root@test:/usr/ports/net/isc-dhcp42-server # vi /usr/local/etc/dhcpd.conf
option domain-name "test.com";
option domain-name-servers test.test.com;

# --- Additional Setting --- #

# This is a very basic subnet declaration.

subnet 192.168.0.0 netmask 255.255.255.0 {
  range 192.168.0.190 192.168.0.195;          //dhcp要給的ip範圍。

查看用戶租用狀況：

# less /var/db/dhcpd/dhcpd.leases

空著的時候：
# The format of this file is documented in the dhcpd.leases(5) manual page.
# This lease file was written by isc-dhcp-4.2.5-P1

server-duid "\000\001\000\001\031@B\012\000\033!\200\206/";

/var/db/dhcpd/dhcpd.leases (END)

如果有租IP的時候：可以從下面的資料看到哪一個號碼是誰在用從幾點到幾點，還可以看到mac和hostname。

# The format of this file is documented in the dhcpd.leases(5) manual page.
# This lease file was written by isc-dhcp-4.2.5-P1

server-duid "\000\001\000\001\031@B\012\000\033!\200\206/";
