[Devstack] What is the meaning of FIXED_RANGE in local.conf?

I didn't understand the effects of FIXED_RANGE parameter in the local.conf file. I've read some answers about it but it is still unclear why I can set any subnet when I create a new private network from the GUI.

See stackrc:

# Set fixed and floating range here so we can make sure not to use addresses
# from either range when attempting to guess the IP to use for the host.

By defining FIXED_RANGE, you ensure that the DevStack scripts know that these addresses are off limits. I think that FIXED_RANGE is also used for the private network in the demo project.

I tried to use that subnet for a private network and worked fine. And the private network of the demo project has different addresses
