Static IP Configuration (netplan)

MediumNetworking15-25 min

The brief

This server currently gets its address from DHCP, but it needs a fixed IP for reliable service discovery. It uses netplan (/etc/netplan/01-netcfg.yaml). Read /root/case/assignment.env for the interface (IFACE), the static address in CIDR form (ADDR_CIDR), and the default gateway (GATEWAY). Convert the interface from DHCP to a static configuration: turn DHCP off and set the address (plus the default route via the gateway). Grading reads the netplan YAML.

What you'll do

Turn off DHCP on the interface
Assign the static address (CIDR)
Set the default gateway
