HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ interface-name

Data type


Default value


IPAddress[ IPAddress...] (A-space delimited list of dotted decimal IP addresses.)

(There is no default value for this entry. DHCP configures the value.)


Specifies an ordered list of gateways that can be used as the default gateway for this system. The Dynamic Host Configuration Protocol (DHCP) configures the list. Packets are sent to the default gateway when they are destined for a subnet to which this computer is not connected, or for which there is no specific destination.

At any time, only one gateway is the default gateway. The other gateways are used, in the order specified, when the system detects that the current default gateway is not operating (See the EnableDeadGWDetect and TcpMaxDataRetransmissions entries.)

If the DefaultGateway entry contains a valid, non-blank value, it takes precedence over this entry. The DefaultGateway entry is configured by the user, not by DHCP.
