An LIR will not get PA addresses smaller than a /32 from RIPE NCC, that is true. /32 is the minimum allocation size for IPv6 PA. An LIR might however get a sub-allocation from a different LIR. There is no minimum sub-allocation size, so it might be a /48. In most cases it wouldn't be wise to sub-allocate such a small block, but it is allowed. I could imagine something like that if for example a non-LIR was running a small hosting business where they want to assign a /56 to each customer. They could get a /48 sub-allocation from an LIR, from which they could make the /56 assignments to their customers. I still would recommend sub-allocating and assigning larger prefixes, but this is just an example. :) Cheers! Sander
