I think the answer to the question is C. But that range does not look right. for m in {1..254..1};do ping -c 1 192.168.101.$m; done I think it should be for m in {1..254};do ping -c 1 192.168.101.$m; done But it seems to work either way.

Agree with you. https://smallbusiness.chron.com/ping-ip-addresses-lan-68381.html ping - c -->You can set the number of times ping is run. By default, it runs until stopped (Linux)
