Hi,

This says that although there are 170k prefixes on the Internet, there are

one explanation for such a large difference (8.5x) between these two

blocks in order to accomodate their needs.
This is an interesting assertion. I thought the majority of announced prefixes was due to folks punching holes in their registry allocated blocks in order to do traffic engineering of one form of another (multi-homing being a form of traffic engineering).

Can you point at the data which backs up your assertion (I'm not disputing it, just a curious)?

Thanks,
