Ping Broadcast ip address of your computer

Ping Broadcast ip address of your computer

I would like to know when you ping IP address of the broadcast on your computer, then run arp -a command, what you would get as information.
for instance, my ip adddress is 10.10.10.10, if I ping 10.10.10.255, then run arp-a, I will get a list of IP addresses with Mac addresses.
I would like to know what the information (list of IP addresses with Mac addresses) represents.

Thanks

Pinging the subnet broadcast address, if allowed will ping all devices on the network.
arp -a lists all the IP addresses on the subnet with their MAC Address.

It's not related.

ARP -A returns addresses with thair MAC address, IF your computer made a contact with that IP address during its uptime.

Shimshey is correct. You get a reply by all devices on the network (if they do not discard the ICMP Echo Request), and that causes the IP and MAC addresses to be stored in the ARP table (in Windows Vista and above: for 15 - 45 seconds random, to comply with RFC4861).

so ping 10.10.10.255 , then arp -a should retrieve every device that is in the subnet 10.10.10.0  ??

Only if 10.10.10.0/24 is the subnet (versus 10.0.0.0/8 or something else), and if the device will answer an IP broadcast (which they should do by default).
