The DHCP server also supports pre-assigning IP addresses to be allocated only to specific MAC addresses and reserving
IP addresses to be used by connected hosts with fixed IP addresses. To reserve an IP addresses for a particular host:

Click Add in the Reserved Addresses field

Enter the Hostname, the Hardware Address (MAC) and the Statically Reserved IP address for the DHCP client
and click Apply
When DHCP has initially allocated hosts addresses it is recommended to copy these into the pre-assigned list so the
same IP address will be reallocated in the event of a reboot.
