我想分裂isc dhcp子网，所以在一部分（0..128）我只有保留的IP，而在另一部分（128..255） – dynamic范围。 我试过这种configuration（波纹pipe），但我总是从第2部分得到一个dynamic范围..即使我启动“节点1”，它应该通过其MAC获得静态IP。
subnet 1.2.3.0 netmask 255.255.255.128 { next-server 1.2.3.199; filename "pxelinux.0"; option routers 1.2.3.1; option subnet-mask 255.255.255.0; option domain-name "host.edu"; option domain-name-servers 1.2.8.; option broadcast-address 1.2.3.255; default-lease-time -1; max-lease-time -1; host node-1 { hardware ethernet 00:00:00:01:01:5d; fixed-address 1.2.3.12; option host-name "node-1"; } } subnet 1.2.3.128 netmask 255.255.255.128 { range dynamic-bootp 1.2.3.130 1.2.3.190; next-server 1.2.3.199; filename "pxelinux.0"; option routers 1.2.3.1; option subnet-mask 255.255.255.0; option domain-name "host.edu"; option domain-name-servers 1.2.8.23; option broadcast-address 1.2.3.255; default-lease-time -1; max-lease-time -1; } 所以有可能做我的任务？ 我需要将networking分开，因为dhcp背后的pipe理软件。否则我不会这样做。
你的configuration应该看起来更像这样：
subnet 1.2.3.0 netmask 255.255.255.0 { range 1.2.3.128 1.2.3.254 next-server 1.2.3.199; filename "pxelinux.0"; option routers 1.2.3.1; option subnet-mask 255.255.255.0; option domain-name "host.edu"; option domain-name-servers 1.2.8.; option broadcast-address 1.2.3.255; default-lease-time -1; max-lease-time -1; host node-1 { hardware ethernet 00:00:00:01:01:5d; fixed-address 1.2.3.12; option host-name "node-1"; } }
