Mac address. How to learn and change?

Users of computers more often than others are forced to monitor changes in technical progress. All kinds of additions, updates and programs are created and perfected almost constantly. To keep abreast of this news means ensuring the operation of your computer at the highest level and getting new opportunities to perform certain tasks. That is why it is increasingly possible to meet discussions on the network concerning specific programs, settings and changing the parameters of the computer.

Each network card is endowed with a unique physical address, which is given to it in the manufacturing process. Often providers provide access to the Internet to this address, which virtually eliminates the possibility of connecting to the network of another computer. And this means that buying a new computer and connecting it to the World Wide Web will be problematic. You need to contact the Internet provider, explain the reason for changing the settings, define a new mac address and other trivia that take free time. Simplify this process by simply changing mac addresses. Replacing this data will allow you to use the services of a "strict" provider without hindrance.

How to carry out this manipulation, not everyone knows. This is due to the fact that users rarely face this issue, and some people even hear about this kind of addresses. The Internet describes a lot of ways to change the "poppy", in this article we will present the simplest and most effective methods. If you decide to change the mac address, how do you find out this combination of numbers? Owners of laptops were lucky. You can determine the mac address of these devices by sticker on the bottom of the computer. Similarly, data is shown on access points, modems and routers. Also these data can be indicated on the packaging of the network device or computer.

If there are no stickers or packages, but you need a mac address, how do you know it in this case? Option one. We need to select "Start" - "Run" and enter in the cmd field. The console window opens, and enter the ipconfig / all command (after the first word, you need a space). Determine the mac address is possible by the phrase "LAN connection - Ethernet adapter: Physical address: 00-0C-F1-AE-B1-34. The last combination, consisting of alternating letters and numbers, and there is a mac address. How to recognize it, it is now clear, but the change of mac addresses is not possible here. Option two (Win 7). Click "Start", then "Control Panel", then "Network and Internet" and then "Network Management Center ..." and select "Adapter parameter changes".

In the window that opens, you should select "Local Area Connection", where in the section with properties you find an inscription corresponding to the name of the desired network card. We move the cursor, and the pop-up window shows the data of the physical address, or you can click on the button "Configure", "Additional" in the same window. In the list that appears, select "Network address" and you will see 12 characters, this is your mac address. How to find out, it's now clear, but in the same window it can be replaced. If you just need to define the mac address, then in the operating systems Windows (2003, XP, Vista, 2008) there is a built-in program (utility) Getmac.exe. The utility works on RPC.

You can start it like this: Start, Run, and type cmd. We write the command getmac / s localhost and get the full list of "mac". You can also learn the mac address if you enter the command nbtstat [-a IP address]. In other OS mac address can be learned as follows:

• Linux - ifconfig -a | Grep HWaddr

• FreeBSD - ifconfig | grep ether

• HP-UX - / usr / sbin / lanscan

• Mac OS X - ifconfig, or in System Settings> Network> find connection> Advanced> Ethernet> Ethernet ID

• QNX4 - netinfo -l

• QNX6 - ifconfig or nicinfo

• Solaris ifconfig -a

When changing mac addresses, do not forget that this data should be unique. The network should not have the same values, not counting the options for substitution. In the case of address spoofing, two computers with the same macs will not be able to connect to each other. If that suits you, then act.
