PowerShell Command: New-NetIPAddress

Mastering Network Configuration with PowerShell: The New-NetIPAddress Command

When it comes to managing network configurations on Windows-based systems, PowerShell is an incredibly powerful tool. One of the essential cmdlets in the PowerShell networking toolkit is New-NetIPAddress. This command is used to configure IP addresses on a network interface, allowing for precise control over network settings. In this article, we will delve into the functionality of the New-NetIPAddress command, providing examples and code samples to illustrate its use.

Understanding the New-NetIPAddress Command

The New-NetIPAddress cmdlet is part of the NetTCPIP module in PowerShell, which provides a range of commands for network configuration. This particular cmdlet is used to create and configure an IP address. Before diving into examples, it's important to understand the parameters that can be used with New-NetIPAddress:

  • -InterfaceAlias: Specifies the alias of the network interface.
  • -IPAddress: Defines the IP address to be assigned to the interface.
  • -PrefixLength: Indicates the length of the subnet mask.
  • -DefaultGateway: Sets the default gateway for the interface.
  • -AddressFamily: Determines the IP address family (IPv4 or IPv6).

Examples of Using New-NetIPAddress

Let's look at some practical examples of how New-NetIPAddress can be used to manage network settings.

Assigning a Static IP Address

# Assign a static IP address to the interface with the alias 'Ethernet'
New-NetIPAddress -InterfaceAlias 'Ethernet' -IPAddress '192.168.1.10' -PrefixLength 24 -DefaultGateway '192.168.1.1'

In this example, we are assigning the static IP address 192.168.1.10 with a subnet mask of 255.255.255.0 (indicated by the prefix length of 24) to the network interface named 'Ethernet'. We are also setting the default gateway to 192.168.1.1.

Configuring an IPv6 Address

# Configure an IPv6 address on the 'Ethernet' interface
New-NetIPAddress -InterfaceAlias 'Ethernet' -IPAddress '2001:0db8:85a3::8a2e:0370:7334' -PrefixLength 64 -AddressFamily IPv6

This command configures an IPv6 address on the 'Ethernet' interface. The -AddressFamily parameter is set to IPv6 to specify the type of IP address being assigned.

Advanced Usage of New-NetIPAddress

For more advanced network configurations, New-NetIPAddress can be combined with other cmdlets to create scripts that automate complex tasks.

Setting Multiple IP Addresses on a Single Interface

# Add multiple IP addresses to the 'Ethernet' interface
$ipAddresses = '192.168.1.11', '192.168.1.12'
foreach ($ip in $ipAddresses) {
    New-NetIPAddress -InterfaceAlias 'Ethernet' -IPAddress $ip -PrefixLength 24
}

This script loops through a list of IP addresses and assigns each one to the 'Ethernet' interface. This is useful for configuring multiple IPs on a single network card.

Why Use PowerShell for Network Configuration?

Using PowerShell for network configuration offers several advantages:

  • Automation: PowerShell scripts can automate repetitive tasks, saving time and reducing the potential for human error.
  • Consistency: Scripts ensure that configurations are applied consistently across multiple systems.
  • Integration: PowerShell can be integrated with other tools and systems for more complex workflows.
