Re: Routing Policy and http://rs.arin.net/ip-allocation.html

  • From: Jared Mauch

	The owner of the block should be announcing the /16  It should not
be chopped up into a whole slew of /24's.  It's not sprints fault.  I would
contact iSTAR.  If their customers are multihomed out of that space,
and (ex:) came to us, we would accept and announce that space, but not
everyone would accept it (such as sprint, and others).

	If the person in that /24 is not connected to iSTAR, they should
have given the address space back already.

	More folks should probally be filtering this:
