You can use PING to find the MAC of the computers in the same workgroup with you,am i right?

several computers share one public address(one router) and each one has

an unique private ip address, the MAC address of others can't be

obtaned by using ARP command, but that which is in the same workgroup

with you can be obtained by using arp -a after it is pinged. am i right? give me some comments!

The Ping command just tells you whether a certain IP address is responding or not. It will not retrieve the MAC for you. Arp can be used to retrive MACs for you. But only of the current "workgroup". MAC addresses are irrelevant after the first hop. Thereafter only IP addresses are relevant. Hence, you can never retrieve MAC addresses of any nodes beyond the first hop. For this reason, MAC addresses arent even transmitted beyond the first hop.
