Hi All,

More whining and bitching from me ... sorry...

So who thinks allowing anyone to route to or from IANA Reserved blocks 
(Bogons) is acceptable?

A few captured packets....

Is there any need to route bogons?  Is there any reason why it cannot be 
filtered (I appreciate 224-239 is a different story)....?

These packets were all originated on the other side of the Pacific to
