The allocation pool spans beyond the subnet cidr

Noticed this "similar" question: https://ask.openstack.org/en/question/64079/failed-to-create-subnet-100100024-for-network-the-allocation-pool-ustart-u1001000-uend-u100100255-spans-beyond-the-subnet-cidr-100100024/

In that case they were outside the span. For me I'm trying to allocate only part of the subnet for dhcp's.

My Error: Resource CREATE failed: BadRequest: resources.subnet_resource: The allocation pool 10.1.0.100-10.1.0.150 spans beyond the subnet cidr 10.0.1.0/24.

No sure why, using a CIDR of 192.168.0.0/24 and 192.168.0.100-192.168.0.150 works ok. Not sure what is happening here.

The online subnet calc is on my side, address range for my CIDR is: 10.0.1.1 - 10.0.1.254 when it comes to usable addresses leaving net and broadcast out.

B.t.w I'm on Newton installed via packstack on a all-in-one-node setup.

Clues?
