HAve youtried doing a BGP lookup for the MX's IP, rather than the whole /16? That will return the smallest aggregate that includes the target IP(s). It's entirely possible that the block is not in the table as a /16, but as a set of sub-aggregates. -Chris On Thu, Jun 14, 2001 at 11:28:36AM -0400, Erik Antelman wrote:

RADB has nothing on this, a New York QWEST looking glass says: Query: bgp IP address: 170.36.73.11 Location: New York Timeout: 20 seconds
% Network not in table
What's up?
