A MAC Address or Media Access Control Address is a unique identifier assigned to every Network Interface Card. In this post, nosotros volition encounter what is MAC Address too how practise you lot modify a MAC Address inwards Windows 10/8. We volition also touching on upon MAC Address filtering, lookup and spoofing.
What is MAC Address
Whether you lot are using a wired network or a wireless one, you lot ask a network carte du jour to connect to other computers too to allow other computers to your computer. While near of us believe that it is the IP address that is pregnant inwards contacting about other calculator on the network, it is non the entirely factor. More of import than IP (Internet Protocol) address is the MAC (Media Access Control) address – an address assigned to the network interface card, thence that it is identified on the network.
A Network carte du jour is a term used inwards curt for a Network interface card. We telephone phone it NIC for short. Every NIC has a MAC address – just similar a postal address thence that the information packets travelling on your network tin ship away accomplish the right NIC too from there, your computer. While the IP address is the software usage of the Network Interface carte du jour (Network carte du jour or NIC), the MAC address is hardware address, without which information packets volition just dice along on roaming on the network, every bit they practise non convey whatever address where to deliver the data. Each information parcel on the network has a header containing MAC address of the calculator you lot wishing to connect to too thence the data. The terminal usage of the information parcel volition incorporate a flake to ascertain if the information flake was correctly delivered or was it corrupted or changed during the transmission.
MAC addresses practise non appear when you lot click on Open Network Adaptors inwards the Windows System Tray. Unlike IP addresses, that are provided past times your Internet access provider or network admins, too may hold out static or dynamic. MAC addresses are assigned past times the manufacturers of network interface cards (NIC). These MAC addresses are built into the cards too are resolved using a method called Address Resolution Protocol. This Address Resolution Protocol start obtains the IP address of the calculator to hold out contacted too thence resolves it into the MAC address earlier embedding it into header of the information packets thence that they are delivered precisely to the calculator intended too non to whatever other calculator inwards the network.
Structure of MAC Address
A MAC address is separated past times total colons, every bit is the IP address (IPv4 addresses). But different entirely iv numeric characters separated past times total colons to larn far expect similar a iv digit sets x 4 parts, the MAC address is a combination of alpha-numeric characters. It is a gear upwards of 6 characters separated past times 6 total colons. Also, different the iv characters used inwards IP address per set, the MAC address employs entirely 2 characters per set. Here is an illustration of a MAC address for your understanding:
00:9a:8b:87:81:80
You tin ship away encounter that it is 6 sets (parts) divided past times total colons too tin ship away incorporate both alphabets too characters. The start 2 or iii sets betoken the code of manufacturers of the network interface carte du jour just similar the start 2 sets of IP address tells you lot where you lot are located.

How To Locate MAC Address of NIC (Network Interface Cards)
To locate the MAC address of your network adaptors, you lot convey to larn to the ascendence line. Press WinKey+R, type cmd inwards the Run dialog box that appears too press Enter key.
Type getmac /v /fo list too press Enter key. The output for each of your NIC adaptor (network adaptors – wired too wireless) volition hold out displayed.
Change MAC Address inwards Windows
It is non advised to modify the MAC address on networks every bit it may practise conflicts too sometimes, may neglect to appear on the network. But if you lot desire to modify the MAC address for about reason, it is an slow process.
1. Press Windows Key + Break or Pause fundamental to opened upwards System Properties window. If the Pause fundamental is combined amongst the Shift key, you lot may ask to press Win+Fn+Pause key.
2. Click on Device Manager to the left side of the System window
3. Once the Device Manager dialog appears, expect for the category named Network Adaptors
4. Click on the summation sign preceding Network Adaptors to encounter all the Network cards attached to your computer;
5. Select the network adaptor whose MAC address you lot wishing to change
6. Right click on the network adaptor too pick out Properties
7. Click on the Advanced tab.
8. In the listing of available options, pick out Locally Administered MAC Address or Network Address; banking corporation complaint that entirely 1 of the 2 options volition appear based on the type of your network adaptor
9. When you lot pick out 1 of the inwards a higher house options, you lot volition larn a text box maxim Value.
10. Type a 6 digit alphanumeric code inwards the Value land afterward selecting the radio button; banking corporation complaint that you lot practise non convey to type the dashes or total colon; if you lot wishing to type 00:4f:gH:HH:88:80, you lot only type 004fgHHH8880 without whatever dashes or total colons; adding dashes may number inwards error
11. Click OK to unopen the dialog box
12. Close other opened upwards dialog boxes (if any) too unopen the Device Manager
That is the simplest method to modify the MAC (Media Access Control) ID of the network adaptor.

MAC Address Spoofing too Filtering
Spoofing is a method past times which you lot modify your MAC address to individual else’s MAC address. That is the mutual notion inwards the globe of Internet. Spoofing is useful when your network won’t permit you lot inwards due to MAC filter restrictions. Hackers also indulge inwards MAC address spoofing.
When you lot modify the MAC address using the inwards a higher house method, you lot are genuinely spoofing the MAC address. The hardware MAC address remains the same, but is given preference entirely when in that place is no other address. If you lot desire to revert to the master MAC address, just follow the inwards a higher house steps too instead of inputting a value, pick out the radio push that says “Not Present” or “No Value“. That volition larn you lot dorsum your master MAC address.
MAC addresses are peculiarly useful when it comes to protecting your network from unwanted connections. All you lot convey to practise is to authorise entirely the MAC addresses that you lot wishing to connect to the Internet or the network. This you lot tin ship away practise it easily using 3rd political party programs. You tin ship away also filter MAC addresses manually past times going to your router page too entering the MAC addresses that are allowed to interact amongst the router.
