The PATH represents the folders in which Windows may look for programs. So, each directory listed in the PATH is a place where you may find installed programs in the form of '.EXE' files. The problem here is that Windows itself is in the PATH. That means that you will find many.EXE files that are not installed programs at all; they're Windows itself.
The method used to find a MAC address depends on the type of network device involved. All popular network operating systems contain utility programs that allow you to find (and sometimes change) MAC address settings.
Raw file to jpeg for mac program. A MAC (media access control) address consists of six pairs of hexadecimals and identifies hardware on a network. Manufacturers embed this unique number at the time of manufacture or store it in the firmware. It's generally not meant to be changed.
Find a MAC Address in Windows
Use the ipconfig utility (with the /all option) to display the computer's MAC address in modern versions of Windows. Very old versions of Windows (Windows 95 and Windows 98) used the winipcfg utility instead.
Both winipcfg and ipconfig may display multiple MAC addresses for one computer. One MAC address exists for each installed network card. Additionally, Windows maintains one or more MAC addresses that are not associated with hardware cards.
For example, Windows dial-up networking uses virtual MAC addresses to manage the phone connection as if it were a network card. Some Windows VPN clients likewise have their own MAC addresses. The MAC addresses of these virtual network adapters are the same length and format as true hardware addresses.
Find a MAC Address in Unix or Linux
The specific command used in Unix to find a MAC address varies depending on the version of the operating system. In Linux and in some forms of Unix, the commandifconfig -a returns MAC addresses.
You also can find MAC addresses in Unix and Linux in the boot message sequence. These operating systems display the computer's MAC address onscreen as the system reboots. Additionally, boot-up messages are retained in a log file (usually var/log/messages or /var/adm/messages).
Find a MAC Address on a Mac
You can find MAC addresses on Apple Mac computers in System Preferences > Network > Advanced > Hardware.
If your system is running Open Transport, the MAC address appears under the Info or User Mode/Advanced screens. If the system is running MacTCP, the MAC address appears under the Ethernet icon.
Summary: How to Find a MAC Address
In summary, here's how to find a computer's MAC address:
- Windows: ipconfig/all, or winipcfg
- Linux and some Unix: ifconfig -a (note the first 'f' in ifconfig; this is easy to confuse with Windows' ipconfig)
- Macintosh: Settings > Network > Advanced > Hardware
MAC addresses were designed to be fixed numbers that cannot be changed; however, there are several valid reasons to change your MAC address.
Change a MAC Address to Work With Your ISP
Most internet subscriptions allow the customer only a single IP address. The Internet Service Provider (ISP) might assign one static (fixed) IP address to each customer. This approach, however, is an inefficient use of IP addresses, which are currently in short supply. The ISP more commonly issues each customer a dynamic IP address that changes each time the customer connects to the internet.

ISPs ensure each customer receives only one dynamic address using several methods. Dial-up and many DSL services typically require the customer to log in with a username and password. Cable modem services, on the other hand, do this by registering and tracking the MAC address of the device that connects to the ISP.
The device with MAC address that is monitored by an ISP can be the cable modem, a broadband router, or the PC that hosts the internet connection. The customer is free to build a network behind this equipment, but the ISP expects the MAC address to match the registered value at all times.
Whenever a customer replaces that device, however, or changes the network adapter inside it, the MAC address of this new equipment will no longer match the one registered at the ISP. In this case, the ISP typically disables the customer's internet connection for security (and billing) reasons.
Although MAC addresses do not reveal geographic location information as IP addresses do, changing MAC addresses can increase internet privacy in some situations.
Change a MAC Address Through Cloning
Some people contact their ISPs to request they update the MAC addresses associated with their subscriptions. This process works but takes time, and internet service will be unavailable until the provider takes action.
Checking account program for mac. A better way to quickly work around this problem is to change the MAC address on the new device so that it matches the address of the original device. Although you cannot change an actual physical MAC address in hardware, you can emulate it in software. This process is called cloning.
Many broadband routers support MAC address cloning as an advanced configuration option. The emulated MAC address appears to the service provider as identical to the original hardware address. The specific procedure of cloning varies depending on the type of router; consult your product documentation for details.
MAC Addresses and Cable Modems
In addition to MAC addresses tracked by ISPs, some broadband modems also track the MAC address of the host computer's network adapter within the home network. If you swap the computer connected to the broadband modem or change its network adapter, your internet connection might not function afterward.

In this case, MAC address cloning is not required. Resetting (including recycling power) on both the cable modem and the host computer will change the MAC address stored inside the modem automatically.
