For example, TCP/IP packet sniffer should be able to see the
Packet source: A's IP+port
Packet destination: B's IP+port
protocol: ICMP: echo request
Sequence:
Ack
And vice versa.
Hope this is helpful | h**********c

who has the given ip, for example
This is the scenairo of ping ip addr.
If name resolution dns is outside the lan, there will be broadcast for who
is the gateway.
This question is not well formed. But think it is a 'make sense' question.
May be a trick for 'switch', switch only tappable for broadcast.
More tricky, tapping switch. Tricky more, VLAN blah blah.
