We recently had to determine is a particular computer was up on the network. Using the command “arp -a” gaves us all the IPs being used on the network. Next was to ping the ip to resolve the name. We used the following command which didn’t work.
“ping 192.168.0.122 -a”
This pinged the machine and told us it was up; however, we needed the machine name. The next command gave us the computer name.
“ping -a 192.168.0.122”
Let us know if this helped you…
