Hello,

Welcome to Webune Suppport Forums.

Today's questions is regarding networking. the question is:

"is it possible to ping a device using only the mac address of the machine? or what tools i can use to check if a device is connected to the network"

ANSWER: the answer is no. IP Address is layer 3 of the OSI Model, and the MAC Address belongs to Layer 2

however, there is a way for example, if i have a network printer connected to my LAN but i can't ping it. the printer may be in your network and you probably are just pinging the wrong ip address for that printer. so how do you find the correct ip address? this is what i would do

go to the printer, usually devices will have the MAC ADDRESS printed on the back, so for example, lets say my printer has this MAC ADDRESS:

01-00-5e-7f-ff-fa

so what i can do is run the arp command. to run the arp utility, open your command terminal. i am using windows 7 for this tutorial, so i will use windows DOS terminal.

ARP COMMAND:
arp -a


it will give you a list of all the devices recorded in your computer:

this is the output on my computer:
C:\Users\MYPC>arp -a

  Internet Address      Physical Address      Type
  192.168.56.255        01-00-5e-7f-ff-fa     static
  224.0.0.22            01-00-5e-00-00-16     static
  224.0.0.252           01-00-5e-00-00-fc     static
  239.255.255.250       ff-ff-ff-ff-ff-ff     static


as you can see from the list, the device with 01-00-5e-7f-ff-fa is IP ADDRESS 192.168.56.1 so i can ping that device now.
