Windows

  • If you're running a Windows machine, bring up a command line prompt. (Start, Run, type "cmd" or "command"). At the command line, type "ipconfig /all". Listed will be your network adapters, with the "Physical Address" being the one your looking for.
  • MAC and IP addresses in Windows NT, 2000 and XP

From the Start button menu, select Run In the dialogue box, type: cmd and press the Enter key At the prompt, type: ipconfig /all The MAC address will be referred to as the Physical Address and is made up of 12 characters e.g. 00-D1-AB-F2-G3-89 Your MAC address is unique to your PC, and Information Services needs it to register your machine on the campus network. The IP address will also be listed on previously networked PCs. Your computer's name will be the Host Name

  • MAC and IP addresses in Windows NT, 2000 and X:

    Select My Network Places on Desktop>Right Click>Properties>Double Click Lan>Support Tab>Details Button

    Here u will find Mac or Physical Address

  • MAC and IP addresses in Windows NT, 2000 and XP

From the Start button menu, select Run In the dialogue box, type: cmd and press the Enter key At the prompt, type: Getmac The MAC address will be referred to as the Physical Address and is made up of 12 characters e.g. 00-D1-AB-F2-G3-89. NOTE: I don't believe the getmac command is a native command to NT/2000/XP, I believe it comes with the applicable resource kit but can be downloaded from Microsoft.

Here's a dirty trick if you can't get to a cmd window. (Some computers are so configured, presumably so you can't hurt yourself.) Open notepad, enter the following line

ipconfig/all > ipout.txt

Then save it to your desktop as ipfind.cmd. Go to your desktop, double click the icon labeled ipfind.cmd. A new icon called ipout will be created. Look in there for the physical address as described above.

Mac OS

  • Mac OS 9: Apple Menu > Apple System Profile > Network > Ethernet Address (or MAC address) Mac OS X: Apple Menu > About This (Computer or Mac) > More Info > Network > Ethernet Address
  • However, under Apple Menu > Apple System Profile > Network Overview>Open transport

    I opened up the AppleTalk Triangle, and found the Physical Address there. This is OS 9.2.2 on a ibook.

Linux

For Linux the command would be ifconfig -a to obtain the MAC address.

1. Click the Start menu button on the Windows taskbar. 2. Click 'Run...' on this menu. 3. Type 'cmd' in the text box that appears. A command prompt window launches on the desktop. 4. In this command window, type 'ipconfig /all'. Details are shown for each of the computer's network adapters. Computers installed with VPN software or emulation software will possess one or more virtual adapters. 5. The 'IP Address' field states the current IP address for that network adapter. 6. The 'Physical Address' field states the MAC address for that adapter.

  1. Open a command window - go to Start > Run and type "command" into the field then click "OK".
  2. Type getmac.
  3. The MAC address will be noted on the column on the left under "Physical Address"

Example C:\>getmac Physical Address Transport Name ============================================= 00-D0-B7-B1-A7-14 \Device\Tcpip_{474E507B-4FCD-428C-A553-304B997C4D96}
Your MAC address is hardcoded to the networking devices, Ethernet, WiFi card, Bluetooth card, etc, and gives it a unique number, no two are the same.

Probably the easiest way to find it would be to go to System Preferances/ Network/ select Advanced/ then upper menu Hardware.

You need to select the Location on the left first to find which one you want, the ethernet, WiFi, etc.

Mac address is the physical address. Mac address is one as a system can have only one NIC card. To know mac address "ipconfig" command can be used in command prompt.
