How to determine your computer's MAC address

How to determine your computer's MAC address

Applies to Windows XP, Windows Vista and Windows 7

1. Click Start - Run

2. Next enter "CMD" and click OK


3. Next at the command prompt type "ipconfig /all" and press enter

At this point all your active connections will list on the screen. Note you may need to scroll back up the window to get to the MAC address info you need. Also keep in mine if you are connected to your wired or wireless connection because both will have a MAC address assigned to them and they will be different.

4. Look under the Local Area Connection if connected to your network via a wired connection or Wireless Network Connection if connecting via a wreless connection.

Once under the right connection you will want to look for the line that shows "Physical Address" this will have what the network cards MAC Address listed.

Note if you have Windows Vista or Windows 7 and you access a lot of different networks then you may have a lot of Tunnel Adapters list that causes overflow in the CMD buffer. If this happens the top part of the "ipconfig /all" report will get cut off. To fix this all you need to is turn off IPV6 in your network properties and reboot your computer. This will remove the ones that are tied to IPV6. After you reboot you should be able to see MAC address for your netork devices. After you get the MAC address it is recommended that you turn IPV6 back on because there is some programs that have been writen for IPV6 for when it becomes a standard.

Here is an example of what "ipconfig /all" looks like on a computer running Windows 7

how do i find information about my address and port?


im guessing here you mean your ip addess and open ports on your computer right ??

ok firstly your computer uses 3 ip address
  1. loop back ,, 127.0.0.1 (slandered) for all computers , this is used for internal progressing and phrasing.
  2. a local ip address ,,This ip vaires what it is basically is the ip address given to your computer by your router ,, its the address that the router recgonises as your computer , so different computers connected to the same router have differect local address.. it usually starts with 192.168.XXX.XXX or 10.0.X.X
  3. Foreign / Internet Ip address, no matter what type of router this address varies for each router!!!!!. lets say you have 7 computer on the same router , each will have the same foreign address but different local address's.
PORTS !!!
will ports are used for different things for example web surfing is port 80, ftp is 21, different software uses cretin ports to allow computers to different machines over the internet or other network to interface with them directly..

Hope i explained all that simply,, well here is how you get the info u need..in all Operating systems the process is a bit different here i will outline 2 ways each,, for XP and for win vista / win 7.. ok lets get started..

XP..

to determine local ip address,,
  • click start , control panel
  • network / internet connections / network connections
  • double click on local area connection or what ever name u see..
  • click support,, there you go see your ip.. click details for more info
alternate method
  • double click on the network connection icon to the buttom right of your screen.. follow last step above

  • click start then run
  • type cmd and hit enter
  • type ipconfig /all and hit enter
that will list all the info about your connection for you..

ok ports in win XP

click start then run,, type cmd and hit enter
type netstat - n

that will list all ports / ip address that they are connection too..
the ports that you see are the open ports.. there is an alternat method to see it in the windows firewall setting but i did not list it since its most incomplete,, background processes dont show up there ,, like a virus..

skip to foreign address !!! BELOW

ok vista...or windows 7

start control panel
network
manage network connection / view or edit network connections
double click on local area network click support if necessary ,, you will see your ip address there (LOCAL)

  • OR ,, click start, in the run box type cmd and hit enter
  • type ipconfig /all hit enter
  • that will list your local address among other things..
PORTS ,, VISTA / WIN 7
click start
in the run box type cmd and hit enter
type netstat -n and hit enter,,
this will list all open ports and the ip address that they are connected to..


FOREIGN ADDRESS
this is easy.. go to http://www.whatismyip.com the address that shows up is your foreign address..

well I hope thats a Fixya, or at least a very helpful after all that typing it would be sad if i didnt answer your question or was wrong abou what you wanted to know.. good luck and let me know if you need any more help..
