Manage IP addresses in PowerShell
PowerShell includes the NETTCPIP module, which consists of TCP/IP-specific cmdlets used to manage network settings for Windows servers and devices. You can use the NETTCPIP cmdlets to add, remove, change, and validate IP address settings.
IP address management cmdlets use the noun "NetIPAddress" in their names. You can also find them by using the Get-Command command with the -Module NetTCPIP parameter.
The following table lists common cmdlets for managing IP address settings.
Table 1: Cmdlets for managing IP address settings
| Cmdlet | Description |
|---|---|
| New-NetIPAddress | Creates a new IP address |
| Get-NetIPAddress | Displays properties of an IP address |
| Set-NetIPAddress | Modifies properties of an IP address |
| Remove-NetIPAddress | Deletes an IP address |
Creating new IP address settings
The New-NetIPAddress cmdlet requires an IPv4 or IPv6 address and either the alias or index of a network interface. As a best practice, you should also set the default gateway and subnet mask at the same time.
The following table lists common parameters for the New-NetIPAddress cmdlet.
Table 2: Parameters for New-NetIPAddress
| Parameter | Description |
|---|---|
| -IPAddress | Defines the IPv4 or IPv6 address to create |
| -InterfaceIndex | Defines the network interface, by index, for the IP address |
| -InterfaceAlias | Defines the network interface, by name, for the IP address |
| -DefaultGateway | Defines the IPv4 or IPv6 address of the default gateway host |
| -PrefixLength | Defines the subnet mask for the IP address |
The following command creates a new IP address on the Ethernet interface:
New-NetIPAddress -IPAddress 192.168.1.10 -InterfaceAlias "Ethernet" -PrefixLength 24 -DefaultGateway 192.168.1.1
The New-NetIPAddress cmdlet also accepts the –AddressFamily parameter, which defines either the IPv4 or IPv6 IP address family. If you don't use this parameter, the address family property is detected automatically.
