Windows XP: Dynamic (DHCP) and static IP address with one network card

There is a method of assigning a number of  static IP addresses to your network card along with the dynamically  assigned one (via DHCP)

1. Configure your network card to automatically get IP address and DNS servers via DHCP.
2. Identify your NIC (network interface card)  GUID (globally unique identifier) by checking the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards\……….\ServiceName registry value, referred to as {NIC-GUID}
3. Modify the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{NIC-GUID}\ SubnetMask and IPAddress values, adding appropriate values in new lines each.
4. Restart (disable and enable) the network card.
5. Check ip addresses with the ipconfig utility. DHCP-assigned and static IP addresses should be listed.
