When an IPv6 boundary is setup, what does it default to "subnet" wise?

Example:

ADSS/Network setup with 2002:cc4b:7d8a:ff00:: /59

SCCM IPv6 Boundary setup with 2002:cc4b:7d8a:ff00

Will this boundary only encompass addresses in the 2002:cc4b:7d8a:ff00 space? Or will it encompass 2002:cc4b:7d8a:ff01:: /59?

I'm assuming since there is no way to specify /59 on the boundary that it will default to /64 and only contain addresses within 2002:cc4b:7d8a:ff00:: /64

Hello,

That could be a long list to add. To simplify the process with New-CMBoundary
