Yes it's called overlapping IPs.

You can turn this off if you would like.

neutron.conf:# Enable or disable overlapping IPs for subnets

Hopefully this help.

I have a question about network configuration.  When I list networks on the openstack controller,

Every subnet has a different tenant ID.
Is this the default behaviour in Openstack?  I.e. the name will be 'net1' and the subnet created will be "" ?
If I source as admin, the list is like this:
