With DHCP client alternate configuration, administrators can easily move a computer among two or more networks, one configured with static IP addresses and one or more configured with DHCP. Alternate configuration provides simplified computer migration (for example, a laptop) among networks without requiring reconfiguration of network adapter parameters, such as IP address, subnet mask, default gateway, preferred and alternate DNS servers, and WINS servers.
Configuration Options
Table 2 shows options that are available for configuring TCP/IP properties for a local area network (LAN) connection.

Description
|
Static IP address configuration
|
When you click Use the following IP address, you can provide values for static IP address settings, such as IP address, subnet mask, default gateway, preferred and alternate DNS servers, and WINS servers. However, if you click Obtain an IP address automatically to change the configuration of your network adapter to a DHCP client configuration, all static IP address settings are lost. Additionally, if you move the computer and configure it for another network, when you return to the original network you must reconfigure the computer with the original static IP address settings.
|
Dynamic IP address configuration without alternate configuration
|
When you click Obtain an IP address automatically, your computer acts as a DHCP client and obtains IP address, subnet mask, and other configuration parameters from your network DHCP server. If the DHCP server is unavailable, the network adapter is configured using IP autoconfiguration.
|
Dynamic IP address configuration with alternate configuration
|
When you click Obtain an IP address automatically, click the Alternate Configuration tab, and type an alternate configuration, you can move your computer from one statically configured network (such as a home network) to one or more dynamically configured networks (such as a corporate network) without changing any settings. If a DHCP server is unavailable (for example, when your computer is connected to your home network), the network adapter is automatically configured with your alternate configuration, and the computer functions correctly on the network. When you move the computer back to the dynamically configured network and the DHCP server is available, the network adapter is automatically configured with the dynamic configuration assigned by the DHCP server. The alternate configuration is used only when the DHCP client cannot locate a DHCP server.
