Hi,
The provisioning network needs to be isolated, typically by using VLANs on the switch:

In general, you can only have one DHCP server on an L2 network (ignoring high-availability DHCP setups).
Thanks, Ollie
I fully agree with Ollie here, you should have the provisioning leg of the undercloud on a isolated VLAN.
However, if you cant get an isolated network segment, and are on Victoria release ironic inspector has a new option that can be used to make the inspector DHCP server only answer requests from known MAC addresses, see: https://review.opendev.org/c/openstack/ironic-inspector/+/753435

Hi all,
I have a situation, when in my network, I have loads of equipment, which I do not control. and Inspection range gets occupied quite
fast.
and in TCP dump I get such messages: DHCP-Message Option 53, length 1: NACK Server-ID Option 54, length 4: DHCPD-IP MSG Option 56, length 21: "address not available"
I have disabled: enabled_node_discovery = false
Anything else?
maybe additional environment options for undercloud I could provide?
