OMG ChatGTP is amazing.  Through some research, I found the following   (I needed to include /32 to specify it is just a single address):

How to Specify a Single IP Address in a Subnet

1. IP Address: The specific IP address you want to designate (e.g., 192.168.0.150).
2. Subnet Mask: The subnet mask in CIDR notation (e.g., /24).

When combined, 192.168.0.150/24 specifies the IP address 192.168.0.150 within the /24 subnet, which covers the range 192.168.0.0 to 192.168.0.255.

Example

To designate just one IP address in a subnet:

• Use 192.168.0.150/32.

The /32 subnet mask means that all 32 bits of the address are fixed, identifying a single specific host (in this case, 192.168.0.150) with no additional addresses in the range.

Summary

• 192.168.0.150/32 specifies the single IP address 192.168.0.150 without including any other addresses. The /32 is the way to indicate an exact IP address with no room for any additional hosts.

if you use a controller, you can add up to 5 IP networks.
