	Hi,

	In many places yet we're discussing prefix aggregation for at least
	193/8, 194/8 and 195/8 IP blocks.

	I was told since a while that some US carriers -such as SprintLink- 
	have decided to filter (id. no more route) prefixes longer than /19.

	My questions is :

	  - is this impleted yet ?
	  - if yes, who does it, for which class(es) of prefixes of which length ?
	  - if no, when do you intend to have this filtering operational ?

	As I'm acting as a "consultant" for the french academic network (Renater)
	I'm interesting in knowing what policy every ISP -specially in the US 
	of A- intend to implement in the near future. 

  Thanks for your help and time,

  Regards,

  +Bernard Tuy.
