为 my.network 中所有连接的计算机获取 IP、MAC 和主机名

Question

I remember doing it a few months ago, but I just forgot the command I used. It was a one liner that produced a table output will all computers in the list: IP MAC HOST For example:

xx.xx.46.118 ab:cd:12:34:aa:aa Intel Corporate (DUP: 2)

In most sites I found arp -a but this output is much more limited (no hostname and it does not contain all addresses).

Can someone point me in the right direction?

Answer 1

sudo arp-scan -l in my Ubuntu machine did the job.
