I have a class B net, chopped up into variously sized subnets. Can the

Has anyone experenced weird amplification levels? i.e I was pinging/mapping
broadcast adressses, and I'm seeing amplification levels of of up to 319
for /27's. When I snoop around further i see that the net is sually
connected to a switch w/ ip, hub w/ ip or terminal server(cisco 5200). But
one machine replys 319 times for the broadcast addr. 


 I spent the last two weekends auditing code... the IRS Tax Code :(.
