In DHCP, a reservation assigns a specific IP address to a specific media access control (MAC) address.
In other words, a DHCP reservation enables you to assign a specific IP address to a specific computer without any special configuration on the client. You must only create the reservation in DHCP and then configure the client to use DHCP.
To determine the MAC address of a target computer running Windows 2000, open a command console on the computer, and type IPCONFIG /ALL. The results list network configuration data for each interface, including the MAC address.
This command also works on Windows XP systems. For Windows 9x and Me systems, use the WINIPCFG utility on the client to determine MAC address.
Once you know the MAC address, follow these steps to create the reservation:
After creating the reservation, either reboot the client computer, or simply refresh its DHCP lease. For Windows 2000 and XP computers, enter IPCONFIG /RENEW at the command line. For Windows 9x and Me computers, use the WINIPCFG utility to renew the DHCP lease.
