Comment 9 for bug 1644433

I disagree that this is a bug. This is working as expected. You set a default_prefixlen of 16, and only supplied a /24 to the subnet pool. Under no circumstance would I expect this to work. The prefixlen parameters are independent of what prefixes are available in the subnet pool. I would suggest that the workflow here is simply incorrect. The ability to set the default prefix length and to request a subnet of specific size exist precisely to deal with these scenarios.

I would think about this differently. In this case, I only have a /24 available. It makes no sense to set my default to /16, or even /24 for that matter. The error message is also quite clear in my opinion. I don't see a bug here.
