Host specific configuration

There maybe a need to set static IP address to a particular host on the network such as printer, web server and etc. In this case it is posible to amend DHCP server configuration to lease a choosen IP address to a specific host defined by its MAC address.

default-lease-time 600;
max-lease-time 7200;

subnet 10.1.1.0 netmask 255.255.255.0 {
  range 10.1.1.3 10.1.1.254;
  option domain-name-servers 10.1.1.1, 8.8.8.8;
  option routers 10.1.1.1;
}

subnet 192.168.0.0 netmask 255.255.0.0 {
}

host printer {
  hardware ethernet 00:16:d3:b7:8f:86;
  fixed-address 10.1.1.100;
}

host web-server {
  hardware ethernet 00:17:a4:c2:44:22;
  fixed-address 10.1.1.200;
}

The above DHCP configuration file will permanently assign the IP address 10.1.1.100 to a host "printer" with a MAC address 00:16:d3:b7:8f:86 and IP address 10.1.1.200 to host "web-server" with MAC address 00:17:a4:c2:44:22.
