Hello,

I have a questions regarding ICMP packets traversing through Hubs and Switches. If connected on a Hub I ping the broadcast address (192.168.0.255) from a host machine ( 192.168.0.100) I get a response from the address 192.168.0.1 with destination address as 192.168.0.100. How is this possible? I do not have machine with the broadcast IP address.

On the other hand, when connected through a switch I do not get any replies and only see request packets on Ethereal.

Can anyone explain this?

Thanks in advance!
