Subnetting legacy Class B networks

  I think we should try keeping separate things separate.
  From my point of view, the information about the allocation boundaries
  as provided by the registries is one thing.
  
  Users (ISP customers), announcing subsets of address-space they got
  assigned somehow, maybe from a legacy class B block, is another thing. 

  If they do so without checking the constraints of the routing system, 
  on the technical side, or the contracts with their ISP(s), on the
  administrative side, then this is outside the responsibility of any
  IP-allocation- or Routing-Registry, I think.
  
  But I'm sure *you* are perfectly aware of that :-)
  Cheers,
  Wilfried.
