Check Mac Address For Ip

Posted on  by 

  1. Ip addr show eth0 Finding the MAC Address of the Linux System. MAC address is another critical parameter of a network device, including your PC’s hardware or a server. Every PC’s network device should have a unique MAC address. Launch Terminal and enter the ip link command: ip link show.
  2. A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on a computer network. MAC addresses are globally assigned to organisations by the Institute of Electrical and Electronics Engineers (IEEE).

IP-based Geolocation is mapping of an IP address or MAC address to the real-world geographic location of an Internet-connected computing or a mobile device. Geolocation involves in mapping IP address to the country, region (city), latitude/longitude, ISP and domain name among other useful things.

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

Check Mac Address For Ip

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.

For

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.

Windows Check Mac Address For Ip

remote_computer : Full name of the remote computer or IP address
username and password are of the account on the remote computer.

Example:

Check Ip Address Mac Terminal

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.

In the VMWare vSphere Client interface you can search virtual machines by their names only. But in some cases it is necessary to find the specific VMWare virtual machine by its IP or MAC (NIC hardware) address.

It is easier to do it using the VMWare PowerCLI that allows youy to search by different virtual machine parameters.

Run the PowerCLI console and connect to your vCenter server or ESXi host using the following command:

Connect-VIServer vcenter-hq.woshub.com -User administrator

To find a virtual machine by its MAC address, use these commands:

$vmMAC='00:52:32:DD:12:91”
Get-VM | Get-NetworkAdapter | Where-Object {$_.MacAddress –eq $vmMAC } | Select-Object Parent,Name,MacAddress

As you can see, the command has returned the name of the virtual machine with its MAC address.

You can also search for a specific MAC address directly in the virtual machine configuration files (VMX) on the VMFS datastore. Connect to your ESXi host via SSH and run the command:

find /vmfs/volumes | grep .vmx$ | while read i; do grep -i '00:52:32:DD:12:91' '$i' && echo '$i'; done

If you have VMware Tools installed on your virtual machines, you can search by the IP address of the guest operating system. For example, you have to find a VM with the specific IP address. Use the following commands:

Check Mac Address For Ip Address

$vmIP='192.168.1.102”
Get-VM * |where-object{$_.Guest.IPAddress -eq $vmIP}|select Name, VMHost, PowerState,GuestId,@{N='IP Address';E={@($_.guest.IPAddress[0])}}|ft

If you know only a part of the IP address, use the following command:

Check Mac Address For Ipod

$vmIP='192.168.”
Get-VM * |where-object{$_.Guest.IPAddress -match $vmIP}|select Name, VMHost, PowerState,@{N='IP Address';E={@($_.guest.IPAddress[0])}} ,@{N='OS';E={$_.Guest.OSFullName}},@{N='Hostname';E={$_.Guest.HostName}}|ft

The command will list the names and types of installed OSs of all virtual machines which IP addresses match this pattern.
