The following are additional DHCP inheritance criteria:

- <span style="color: #000000">**Range Creation**</span><span style="color: #000000">: </span>The range should automatically inherit its value from the parent subnet when the parent subnet is assigned to a NIOS-X Server.
- <span style="color: #000000">**Preview inheritance**</span><span style="color: #000000">: </span>Previewing inheritance applies only to a range assigned to a NIOS-X Server or an HA Group.
- <span style="color: #000000">**Fixed Address**</span><span style="color: #000000">: </span>Display NIOS-X server(s) from the parent container (Subnet or Range). The fixed address follows the same inheritance model as above. If a single NIOS-X server is assigned, the system displays only that server and hide the preview inheritance. If an HA Group is assigned or if the count exceeds one, the system displays the preview inheritance with a drop-down selector.
