Exclude IPs from the DHCP scope

When creating a DHCP scope I recommend excluding a small range for static IP assignments. Yes, I know in the previous tip I said don’t use static assignments but you will need it for infrastructure equipment.

Your networks will have a default route that will be a router so you definitely want that excluded from the DHCP pool. You may also run into other equipment that requires a static IP so it’s good to have a small range of IPs excluded from the DHCP pool for these devices. For example, I’ve seen various alarms and security devices that need a static IP so I just provide an IP from the exclusion range.

Here is a screenshot of a data VLAN used for workstations and laptops with the exclusion of 10.2.10.1 to 10.2.10.10.
