Pengertian MAC Address (Media Access Control Address) adalah sebuah alamat jaringan yang diimplementasikan pada lapisan data-link dalam tujuh lapisan model OSI, yang merepresentasikan sebuah node tertentu dalam jaringan. Dalam sebuah jaringan berbasis Ethernet,
 MAC address merupakan alamat yang unik yang memiliki panjang 48-bit (6
byte) yang mengidentifikasikan sebuah komputer, interface dalam sebuah
router, atau node lainnya dalam jaringan. MAC Address juga sering
disebut sebagai Ethernet address, physical address, atau hardware address.






















MAC Address mengizinkan perangkat-perangkat dalam jaringan agar dapat
 berkomunikasi antara satu dengan yang lainnya. Sebagai contoh, dalam
sebuah jaringan berbasis teknologi Ethernet, setiap header dalam frame Ethernet mengandung informasi mengenai MAC address dari komputer sumber (source) dan MAC address dari komputer tujuan (destination). Beberapa perangkat, seperti halnya bridge dan switch Layer-2 akan melihat pada informasi MAC address dari komputer sumber dari setiap frame
 yang ia terima dan menggunakan informasi MAC address ini untuk membuat
"tabel routing" internal secara dinamis. Perangkat-perangkat tersebut
pun kemudian menggunakan tabel yang baru dibuat itu untuk meneruskan
frame yang ia terima ke sebuah port atau segmen jaringan tertentu di
mana komputer atau node yang memiliki MAC address tujuan berada.





Dalam sebuah komputer, MAC address ditetapkan ke sebuah kartu jaringan (network interface card/NIC)
 yang digunakan untuk menghubungkan komputer yang bersangkutan ke
jaringan. MAC Address umumnya tidak dapat diubah karena telah dimasukkan
 ke dalam ROM.
 Beberapa kartu jaringan menyediakan utilitas yang mengizinkan pengguna
untuk mengubah MAC address, meski hal ini kurang disarankan. Jika dalam
sebuah jaringan terdapat dua kartu jaringan yang memiliki MAC address
yang sama, maka akan terjadi konflik alamat dan komputer pun tidak dapat
 saling berkomunikasi antara satu dengan lainnya. Beberapa kartu
jaringan, seperti halnya kartu Token Ring mengharuskan pengguna untuk
mengatur MAC address (tidak dimasukkan ke dalam ROM), sebelum dapat
digunakan.










MAC address memang harus unik, dan untuk itulah, Institute of Electrical and Electronics Engineers (IEEE)
 mengalokasikan blok-blok dalam MAC address. 24 bit pertama dari MAC
address merepresentasikan siapa pembuat kartu tersebut, dan 24 bit
sisanya merepresentasikan nomor kartu tersebut. Setiap kelompok 24 bit
tersebut dapat direpresentasikan dengan menggunakan enam digit bilangan heksadesimal,
 sehingga menjadikan total 12 digit bilangan heksadesimal yang
merepresentasikan keseluruhan MAC address. Berikut merupakan tabel
beberapa pembuat kartu jaringan populer dan nomor identifikasi dalam MAC
 Address.





 
Berikut cara merubah MAC address di Windows XP, WIndows 7, Windows 8/8.1 & Windows 10





Sementara pakai bahasa inggris ulu ya biar pada pinter ^_^, 





nanti kalau ada waktu saya terjemahin + tambahin lagi trick nya..






Method One:





1. Access your network connection properties and select the configure option.







2. Select the Advanced Tab and then select Network Address. From here
you need change the Value to custom and enter your desired MAC Address.
Remember that this can only be twelve numbers in length.







3. Check to see if your MAC has changed using the “ipconfig /all”
command in Command Prompt. If your MAC Address is still the same as your
 original please move to the next method.









Method Two:








1. Open your terminals Registry Editor by typing “regedit” into your start menus search box and pressing enter.







2. Once Registry Editor has opened navigate through the following path:



CODE :







HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Class > {4D36E972-E325-11CE-BFC1-08002BE10318}






3. After you have navigated to this location you will need to create a
new entry in the folder so that you can store the information for the
new / fake MAC Address.  To do this right click anywhere in the
right-hand pane and select “New” > “String Value”







4. Rename this new entry to “NetworkAddress” and modify the details of
this entry to the desired result. To edit the details simply right click
 the entry and select “modify”. Remember to ensure that the value is
exactly 12 digits long, the length of a MAC Address.







5. Restart your network adapter and then view your MAC Address using an
ipconfig /all command in command prompt. If your MAC Address is still
the same as your original please move to the next method.









Method Three:







1. Step three is the last resort method but is also probably the
quickest. Simply download and install Technitium MAC Address Changer
from the below link:




CODE :








(Tunggu 5 detik, lalu klik tulisan "SKIP AD" di pojok kanan atas)
(wait 5 seconds, than click "SKIP AD")







-After Download.. Extract With WinRAR/WinZip



-INSTAL> RIGHT CLICK > RUN AS ADMINISTRATOR



2. After installation you need to run the application and edit in your
desired MAC Address in the “Change MAC Address” field and press the
“Change Now” button. You will see an example of this in the screenshot
below.










3. After you have done this a message box will appear informing you that
 your MAC Address has been successfully changed. To be sure of this
simply use the checks outlined in Method 1 point three.







notes:



This application is unable to change MAC address of many wireless network/WIFI adapters on
Windows Vista and above
. Its been observed, and I had quite a few email
feedback confirming that, on the same hardware with Windows XP
installed, everything seems to work fine!



I also had one email feedback saying that TMAC couldn't change MAC
address of Wifi on Windows XP machine after updating drivers. Reverting
back to old drivers again made things work.



This issue is observed only on wifi adapters, while you can change the
MAC address on Ethernet adapters without any fuss. This tells that the
network adapter drivers are actually preventing users from changing MAC
address.




A simple workaround would let you change MAC address on most wifi
adapters if you want to just make sure your original MAC address is not
exposed. You just have to set the first octet of MAC address to "02",
instead on what normally is "00".



If the MAC address didnt change, try to disable and re-enable the Wifi network adapter manually from Network and Sharing Center > Change adapter settings (or you can just enter Network Connections in Windows Explorer location bar).



While I am not very sure why it works with "02" I think it has to do with the MAC Address specification which uses first octet to set flags (see image below; courtesy Wikipedia.org)










Setting first octet "02" actually sets the b2 bit indicating that the
MAC address is locally administered. Looking at this MAC address thus
indicates that the MAC address is changed by local machine
administrator. But, its still good if you just want to hide your
original MAC address instead of spoofing someone's MAC address.



Another guess on why this works may be due to Windows Network Bridge feature. When you bridge 2 or more network adapters in Windows, the Network Bridge
 sets its MAC address to the first network adapter added to it with the
first octet set to "02". Thus, if the network adapter drivers didn't
allow the change, it would make the feature not work.


Linux



Modern Linux distributions like Ubuntu typically use Network Manager, which provides a graphical way to spoof a MAC address.

For example, on Ubuntu you’d click the network icon on the top panel,
 click Edit Connections, select the network connection you want to
modify, and click Edit. On the Ethernet tab, you’d enter a new MAC
address under “Cloned MAC address” and save your changes.

You can also do this the old-fashioned way. This involves taking the
network interface down, running a command to change its MAC address, and
 then bringing it back up. Be sure to replace “eth0″ with the name of
the network interface you want to modify and enter the MAC address of
your choice:



sudo ifconfig eth0 down

sudo ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx

sudo ifconfig eth0 up

You&#8217;ll have to modify the appropriate configuration file under
/etc/network/interfaces.d/ or the /etc/network/interfaces file itself if
 you want this change to always take effect at boot time. If you don&#8217;t,
your MAC address will be reset when you restart.<br />
<h3>
Mac OS X</h3>
Mac OS X&#8217;s System Preferences pane displays each network interface&#8217;s
MAC address, but doesn&#8217;t allow you to change it. You can do so with a
single command.<br />
Open a Terminal window (<a href="http://www.howtogeek.com/188530/a-windows-users-guide-to-mac-os-x-keyboard-shortcuts/">press Command + Space</a>,
 type Terminal, and press Enter.) Run the following command, replacing
en0 with the network interface&#8217;s name and filling in your own MAC
address:<br />
<blockquote>
sudo ifconfig en0 xx:xx:xx:xx:xx:xx</blockquote>
The network interface will generally be either en0 or en1, depending
on whether you want to configure a Mac&#8217;s Wi-Fi or Ethernet interface.
Run the <b>ifconfig</b> command to see a list of interfaces if you&#8217;re not sure of the appropriate network interface&#8217;s name.<br />

As on Linux, this change is temporary and will be reset when you next
 reboot. You&#8217;ll need to use a script that automatically runs this
command on boot if you&#8217;d like to permanently change your Mac address.<br />
