In Linux, how can I see all MAC addresses present in a broadcast domain, and how can I configure a broadcast domain?
You can see all MAC addresses present in a broadcast domain by executing the following command :-
nmap -sP 172.18.72.0/24
for more help run
A broadcast domain is a logical division of a computer network, in which all nodes can reach each other by broadcast at the data link layer. A broadcast domain can be within the same LAN segment or it can be bridged to other LAN segments.
In terms of current popular technologies: Any computer connected to the same Ethernet repeater or switch is a member of the same broadcast domain. Further, any computer connected to the same set of inter-connected switches/repeaters is a member of the same broadcast domain. Routers and other higher-layer devices form boundaries between broadcast domains.
So you couldn't configure broadcast domain on your Machine, but you can found all machines using
nmap as mentioned in previous answer.
