What is a MAC Address and how to change a MAC Address

When you connect to internet and IP is assigned to your computer by your ISP.
At the ISP's end your ip is logged for records and MAC address is stored for security reason.

MAC is short for Media Access Control. The MAC address is the hardware address that uniquely identifies each network device on the Caltech network. The MAC address is also sometimes called the ethernet address.

How to check your IP Address assigned by ISP

When we connect to the internet, via internet service provider (ISP) or any kind of LAN connection, you are assigned an IP address. This address identifies your computer from the other computers on the internet. Your IP address can be either static, meaning it never changes, or dynamic, meaning each time you dial-in or login you are assigned a new address for that session. Check with your internet service provider or network administrator to find out if your computer uses static or dynamic IP addressing.

The commands below will show you the IP address of your computer. If you use a home router to connect to the Internet, the IP shown from these commands will not be your public IP address (it will be your internal IP address). Internal IP address start with a 10.10 or 192.168.

If you want to see your settings, in Windows 95/98 try the following:
Go to Start/Run and do the command winipcfg
That will bring up a network screen with your values.

Windows 2000, XP, Vista you can go to a command prompt and do:
ipconfig

On the Macintosh to get your IP address try the following:
Apple Menu --> Control Panels --> TCP/IP Control Panel

On Mac OS X:
1. Open system preferences
2. Under internet and network, click 'network'
It will show you your IP address..

If you receive a dynamic IP address from your internet provider, it will likely be different on your next session. So if you need your IP address for later use, please check when you log on for that session.
