Easy Question:
If a router allow directed broadcast and then I ping the broadcast address
of the subnet, all the computers in the subnet should reply me?
Many Thanks in advance
Regards.
Yes... The router would broadcast the ping request sent to the broadcast
address, then all the computers in the subnet should reply, as long as
computer isn't configured to not reply to ping requests.
Now with that said, Ping client software will (usually) only show the first
computer that replied on screen, and drop the rest.
Here are some ping results using ethernet sniffing software:
No. Time Source Destination
