          1. use a NAD with ipam: dhcp.
    2. delete the dhcp deamon pod on the smae node as your workload.
    3. observe the lease expire on dhcp server / get reissued to a different pod causing network outage from duplicate addresses.

      dhcp-daemon pod does not get evicted before workloads. because of system-node-critical
