It is not aways possible to extend a subnet due holes in your address space. Better way is to add another subnet to the network. Underlying plugin should be able handle this properly. Some WiFI vendors call it VLAN pooling. Or some call it multi netting.

We also did allocation pool shrinking but always make sure there is no IP associated (or even assigned to a project) from out of the new range. Check the neutron MySQL table: ipallocationpools.

Hi Sam, Unfortunately we do not support updating the allocation-pools on subnets at this time. This is something that we should definitely fix though in neutron.
