Netsh commands for Interface IP

  • Article

You can use commands in the Netsh Interface IP context to configure the TCP/IP protocol (including addresses, default gateways, DNS servers, and WINS servers) and to display configuration and statistical information.

You can run these commands from the Windows XP command prompt or from the command prompt for the Netsh Interface IP context. For these commands to work at the Windows XP command prompt, you must type netsh interface ip before typing commands and parameters as they appear in the syntax below. To run these Netsh commands on a remote Windows 2000 Server, you must first use Remote Desktop Connection to connect to a Windows 2000 Server that is running Terminal Server. There might be functional differences between Netsh context commands on Windows 2000 and Windows XP.

set address

Configures an IP address and a default gateway on a specified interface.

Syntax

set address [name=]InterfaceName [source=]{dhcp | static [addr=]IPAddress [mask=]SubnetMask [gateway=]{none | DefaultGateway [[gwmetric=]GatewayMetric]}}

Parameters

[ name = ] InterfaceName   : Required. Specifies the name of the interface for which you want to configure address and gateway information. The InterfaceName parameter must match the name of the interface as specified in Network Connections. If InterfaceName contains spaces, use quotation marks around the text (for example, "Interface Name").

[ source= ]{ dhcp | static [ addr= ] IPAddress [ mask= ] SubnetMask [ gateway= ]{ none | DefaultGateway [[ gwmetric= ] GatewayMetric ]}} : Required. Specifies whether the IP address to configure originates from a Dynamic Host Configuration Protocol (DHCP) server or is static. If the address is static, IPAddress specifies the address to configure, and SubnetMask specifies the subnet mask for the IP address being configured. If the address is static, you must also specify whether you want to leave the current default gateway (if any) in place or configure one for the address. If you configure a default gateway, DefaultGateway specifies the IP address of the default gateway to be configured, and GatewayMetric specifies the metric for the default gateway to be configured.

/? : Displays help at the command prompt.

Remarks

  • You can use this command to switch an interface between DHCP configuration and static configuration. If the interface is configured statically, the DNS and WINS server addresses for this interface must also be statically configured.

  • Omitting the DefaultGateway parameter does not clear gateway configuration but preserves whatever was previously configured.

add address

Adds an IP address and a default gateway on a specified interface configured with a static IP address.

Syntax

add address [name=]InterfaceName [addr=]IPAddress [mask=]SubnetMask [[gateway=] DefaultGateway [gwmetric=]GatewayMetric]

Parameters

[ name= ] InterfaceName   : Required. Specifies the name of the interface for which you want to add address and gateway information. The InterfaceName parameter must match the name of the interface as specified in Network Connections. If InterfaceName contains spaces, use quotation marks around the text (for example, "Interface Name").

[ addr= ] IPAddress [ mask= ] SubnetMask   : Required. Specifies the IP address to add and the subnet mask for that IP address.

[ gateway= ] DefaultGateway [ gwmetric= ] GatewayMetric   : Specifies the IP address of the default gateway to add and the metric for that default gateway.

/? : Displays help at the command prompt.

delete address

Deletes an IP address or a default gateway on a statically configured interface.

Syntax

delete address [name=]InterfaceName [addr=] IPAddress [[gateway=]{DefaultGateway | all}]

Parameters

[ name= ] InterfaceName   : Required. Specifies the name of the interface for which you want to delete address and gateway information. The InterfaceName parameter must match the name of the interface as specified in Network Connections. If InterfaceName contains spaces, use quotation marks around the text (for example, "Interface Name").

[ addr= ] IPAddress   : Required. Specifies the IP address to delete.

[ gateway= ]{ DefaultGateway | all } : Specifies whether to delete one default gateway or all default gateways. If only one default gateway should be deleted, DefaultGateway specifies the IP address of the default gateway to be deleted.

/? : Displays help at the command prompt.

Remarks

  • This command will not delete the last IP address on the interface.

show address

Displays information about static IP addresses and default gateways on a specified interface. Used without parameters, show address displays address information for all interfaces.

Syntax

show address [[name=]InterfaceName]

Parameters

[ name= ] InterfaceName   : Specifies the name of the interface for which you want to display address information. The InterfaceName must match the name of the interface as specified in Network Connections. If InterfaceName contains spaces, use quotation marks around the text (for example, "Interface Name").

/? : Displays help at the command prompt.

Remarks

  • For interfaces configured using DHCP, use the ipconfig command to display the assigned IP addresses, lease parameters, and other DHCP information.

set dns

Configures a DNS server address for a specified interface.

Syntax

set dns [name=]InterfaceName [source=]{dhcp | static [addr=]{DNSAddress | none}} [[ddns=]{disabled | enabled}] [[suffix=]{interface | primary}]

Parameters

[ name= ] InterfaceName   : Required. Specifies the name of the interface for which you want to set DNS information. The InterfaceName parameter must match the name of the interface as specified in Network Connections. If InterfaceName contains spaces, use quotation marks around the text (for example, "Interface Name").

[ source= ]{ dhcp | static [ addr = ]{ DNSAddress | none }} : Required. Specifies whether the IP address of the DNS server is configured by DHCP or is static. If the IP address is static, DNSAddress specifies the IP address of the DNS server to configure, and none specifies that the DNS configuration should be removed.

[ ddns= ]{ disabled | enabled } : Specifies whether the computer should attempt DNS dynamic update registration of the IP addresses of this connection and the full computer name. The full computer name is specified in the Control Panel item System on the Computer Name tab. The enabled parameter specifies that the attempt should occur. The disabled parameter specifies that the attempt should not occur.

[ suffix= ]{ interface | primary } : Specifies whether the computer should attempt DNS dynamic update to register the IP addresses and the connection-specific domain name of the specified connection in addition to the full computer name. The connection-specific DNS name of this connection is the concatenation of the computer name (which is the first label of the full computer name) and the DNS suffix of this connection. The interface parameter specifies that both the full computer name and connection-specific name should be registered. The primary parameter specifies that only the full computer name should be registered.

/? : Displays help at the command prompt.

Remarks

  • If the interface is already statically configured, the static parameter replaces the existing list of DNS server addresses with the one specified in the command.

  • The default setting for ddns= is enabled.
