We can find mac address (physical address) of a computer using the command ‘getmac‘. This can be used to get mac address for remote computers also. Below are few examples on how to use this command. It works on XP, Vista, Windows 7, Server 2003 and Server 2008 operating systems.
Get mac addresses from CMD
Find your computer's name and network address on Mac. If other people want to locate your Mac on the network, they need to know your computer's name or network address. Your Mac has several identifiers that people may look for on the network: computer name, local hostname (or local network name), and network address. CC Get MAC Address is a handy tool for finding MAC address and computer name from IP address. You can use it to find MAC address, computer name and IP address of a computer on LAN even out of your LAN range. Network administrator can use this handy tool to lookup mac address of each computer on the LAN. Can find out who change his IP or mac. After taking down the mac address from the local switch using show mac-address-table command, log on to nearby router or L3 switch and issue the show arp to get the IP address. I hope you must be able to find the IP address from the router as the device connected to F0/7 of switch has to comminicate over the router at some point of time. Use this method to obtain the MAC Address of your local computer as well as query remotely by computer name or IP Address. Hold down the 'Windows Key' and press 'R'. Type 'CMD', then press 'Enter'. You can use one of the following commands: GETMAC /s computername – Get MAC Address remotely by Computer Name.
Just run the command getmac to get the mac addresses. Find an example below.
This command does not show mac addresses for the network connections which are disabled. You can run ncpa.cpl and check which NICs are disabled. Further, I have received comments that this command does not help identify the mac address for a specific device. For example, if I need to get the mac address for my WiFi card, output of getmac command is not helpful. We can use ipconfig command to deal with this.
Get mac address of a remote computer
We can retrieve the mac addressses for a remote computer using nbtstat command.
Example:
Alternatively, We can run the below command to retrieve the mac addresses of a remote computer.
remote_computer : Full name of the remote computer or IP address
username and password are of the account on the remote computer.
Example:
If you do not want to specify the password, you can skip /p parameter. You will be prompted to enter the password and the command execution will take place after that.
Errors:
Using getmac command we can retrieve the mac addresses of the machines running windows OS only. If you try this for a Linux machine you would get the error 'The RPC server is unavailable.'
If you provide incorrect password, the command would fail with the error message 'Logon failure: unknown user name or bad password.'

This post explains getting MAC address and IP address of devices connected to ESP8266. Typically, the MAC address is only visible on each end of a 'hop' in a packet so if you are going from some device via WiFi through the router to some other device, the MAC address you would see would be from your device and the router. The router will typically have a table of IP addresses and associated MAC addresses for those devices that it has handed out an IP address to via DHCP.
A media access control address (MAC address) of a device is a unique identifier assigned to network interfaces for communications. In this Example we will get MAC address of all connected devices to the ESP8266. ESP8266 acts as WiFi access point.
