So I created a default fabric for PXE to use within a region on 10.0.192.0/22.
I reserved 10.0.192.1 -> 10.0.199.254 for static IP Usage and then I reserved a dynamic range from 10.0.200.1 -> 10.0.250.254 for the DHCP server to hand out IPs.
The utilization reads 1279 of 16382 IPs Available. Though I’ve only assigned 3 addresses (1 static 10.0.192.2 and 2 dynamic 10.0.199.255 & 10.0.200.0
