dhcp服务器静态分配ip地址，被其他电脑分配到的问题

我的dhcp服务器配置如下：dhcpd.conf文件内容
[root@CrcszProxy root]# more /etc/dhcpd.conf

分配的地址池是192.168.0.50 192.168.0.200，其中有些电脑我希望每次分配的ip地址相同，故我通过host命令进行设置，如上所述。对ip和mac在dhcp配置文件中进行了绑定。运行正常，近日发现在上面某些固定ip地址电脑（如hufuliang）没有开机的情况下，原本固定分配给他的192.168.0.88地址，被局域网中其他动态获取地址的电脑获得，这种情况正常吗，按照我的理解如果在dhcp的配置文件中通过host对ip和mac进行了设置的话，应该是不管该机器是否在使用这个ip地址，都不应该分配给其他的动态获取地址的客户端呀？
请大家帮我看一下，如果我要实现绑定了就不会分配给其他的电脑，该怎么样修改我的配置文件？
谢谢

动态分配的地址池，要和静态绑定的IP段不能重合。否则就会出现你说的现象。

谢谢您的回复，我回去改改配置
