In the DOS prompt, the command:

• ipconfig /all
  is used for displaying your computer IP information.  You use this often to check you have network connectivity. 

From the results:

The MAC address or unique address that the computer Network Interface Card (NIC) has is shown as the 'Physcial Address: 00-C0-4F-92-92-0B'.

The 'IP Address' is the unique address on the internet assigned to your computer.  If this does not appear, then you do not have network connectivity.

• ipconfig /renew
  is used for renewing the IP address that the computer obtains from DHCP.  You need to do this when you move your laptop from one subnet to another.
• ipconfig /release
  is used for releasing the IP address that the computer has obtained from DHCP

/? Display this help message.
/all Display full configuration information.
/release Release the IP address for the specified adapter.
/renew Renew the IP address for the specified adapter.

The default is to display only the IP address, subnet mask and default gateway
for each adapter bound to TCP/IP.

For Release and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or renewed.
