我遇到了dhcpd的麻烦。
对于一个大的广域网，有很多255.255.255.252子网，我们使用DHCP将一个IP推送到所有这些站点。
每个子网的定义如下
subnet 10.91.17.0 netmask 255.255.255.252 { option routers 10.91.17.1; option subnet-mask 255.255.255.252; pool { allow members of "Devices"; range 10.91.17.2 10.91.17.2; } } 一切正常，但系统日志填充消息如下。 另请参阅tcpdump。
客户永远不会在网站上进行更改，因此每次请求时都应该获得相同的地址。
任何想法，为什么我不断收到的消息，请
谢谢
