ISC DHCP: Pin a Device with a Static Reservation

MediumNetworking15-25 min

The brief

A device must always get the same IP. The DHCP server already serves the LAN; add a static host reservation. Your assignment is in /root/case/assignment.env (HOSTNAME, MAC, FIXED_IP).

Add a host block to /etc/dhcp/dhcpd.conf:

host HOSTNAME {

hardware ethernet MAC;

fixed-address FIXED_IP;

}

Match the device by its MAC and pin it to FIXED_IP (keep it out of the dynamic pool). Grading reads dhcpd.conf (dhcpd need not be running). See /root/case/brief.txt.

What you'll do

Add a named host reservation block
Match the device by its hardware (MAC) address
Assign it a stable fixed-address
Understand static reservations vs the dynamic pool
