If the network adapter has a configured VLAN number, you can view it:

Get-NetAdapter | ft Name, Status, Linkspeed, VlanID

Here is how you can find out the information about the network adapter driver that you are using:

Get-NetAdapter | ft Name, DriverName, DriverVersion, DriverInformation, DriverFileName

List the information about physical network adapters (PCI slot, bus, etc.):

Get-NetAdapterHardwareInfo

Disable the IPv6 protocol for the network interface:

Get-NetAdapterBinding -InterfaceAlias Ethernet0 | Set-NetAdapterBinding -Enabled:$false -ComponentID ms_tcpip6

Disable the NetBIOS protocol for a network interface:

Set-NetAdapterBinding -Name Ethernet0 -ComponentID ms_netbios -AllBindings -Enabled $True

How to Get an IP Address Settings with PowerShell?

To get current network adapter settings in Windows (IP address, DNS, default gateway):

Get-NetIPConfiguration -InterfaceAlias Ethernet0

To display more detailed information about the network interface TCP/IP configuration, use the command

Get-NetIPConfiguration -InterfaceAlias Ethernet0 -Detailed

In this case, the assigned network location (profile) (NetProfile.NetworkCategory) of the interface, MTU settings (NetIPv4Interface.NlMTU), whether obtaining an IP address from DHCP is enabled?(NetIPv4Interface.DHCP), and a number of other useful information are displayed.

To get the IPv4 interface address only:

(Get-NetAdapter -Name ethernet0 | Get-NetIPAddress).IPv4Address

Return the value of the interface’s IP address only:

(Get-NetAdapter -Name ethernet0 | Get-NetIPAddress).IPv4Address

Display a list of the network protocols that can be enabled or disabled for a network adapter:

Set Static IP Address on Windows Using PowerShell

Let’s try to set a static IP address for the NIC. To change an IP address, network mask, and default gateway for an Ethernet0 network interface, use the command:

Get-NetAdapter -Name Ethernet0| New-NetIPAddress –IPAddress 192.168.2.50 -DefaultGateway 192.168.2.1 -PrefixLength 24

You can set an IP address using an array structure (more visually):

$ipParams = @{
InterfaceIndex = 8
IPAddress = "192.168.2.50"
PrefixLength = 24
AddressFamily = "IPv4"
}
New-NetIPAddress @ipParams

If a static IP address is already configured and needs to be changed, use the Set-NetIPAddress cmdlet:

Set-NetIPAddress -InterfaceAlias Ethernet0 -IPAddress 192.168.2.90

To disable obtaining an IP address from DHCP for your adapter, run the command:

Set-NetIPInterface -InterfaceAlias?Ethernet0?-Dhcp Disabled

Remove static IP address:

Remove-NetIPAddress -IPAddress "xxx.xxx.xxx.xxx"

Set DNS Server IP Addresses in Windows with PowerShell

To set the preferred and alternate DNS server IP addresses in Windows, use the Set-DNSClientServerAddress cmdlet. For example:

Set-DNSClientServerAddress –InterfaceIndex 8 –ServerAddresses 192.168.2.11,10.1.2.11

You can also specify DNS nameserver IPs using an array:

$dnsParams = @{
InterfaceIndex = 8
ServerAddresses = ("8.8.8.8","8.8.4.4")
}
Set-DnsClientServerAddress @dnsParams

After changing the DNS settings, you can flush the DNS resolver cache (equivalent to ipconfig /flushdns ):

Clear-DnsClientCache

Managing Routing Tables with PowerShell

The Get-NetRoute cmdlet is used to display the routing table.

Get the default gateway route for a physical network interface in Windows:

Get-NetAdapter -Physical | ? {$_.Status -eq "Up"}| Get-netroute| where DestinationPrefix -eq "0.0.0.0/0"

To add a new route, use the New-NetRoute cmdlet:

New-NetRoute -DestinationPrefix "0.0.0.0/0" -NextHop "192.168.2.2" -InterfaceIndex 8

This command adds a permanent route to the routing table (similar to route -p add). If you want to add a temporary route, add the -PolicyStore "ActiveStore" option. This route will be deleted after restarting Windows.

Remove a route from the routing table:

Remove-NetRoute -NextHop 192.168.0.1 -Confirm:$False

PowerShell: Change Adapter from Static IP Address to DHCP

To configure your computer to obtain a dynamic IP address for the network adapter from the DHCP server, run this command:

Set-NetIPInterface -InterfaceAlias Ethernet0 -Dhcp Enabled

Clear the DNS server settings:

Set-DnsClientServerAddress –InterfaceAlias Ethernet0 -ResetServerAddresses

And restart your network adapter in order to automatically obtain an IP address from the DHCP server:

Restart-NetAdapter -InterfaceAlias Ethernet0

If you previously had a default gateway configured, remove it:

Set-NetIPInterface -InterfaceAlias Ethernet0| Remove-NetRoute -Confirm:$false

If you need to reset all the IPv4 settings for the computer’s network interfaces and switch them to obtain a dynamic IP address from DHCP, use the following script:

$IPType = "IPv4"
$adapter = Get-NetAdapter | ? {$_.Status -eq "up"}
$interface = $adapter | Get-NetIPInterface -AddressFamily $IPType
If ($interface.Dhcp -eq "Disabled") {
If (($interface | Get-NetIPConfiguration).Ipv4DefaultGateway) {
$interface | Remove-NetRoute -Confirm:$false
}
$interface | Set-NetIPInterface -DHCP Enabled
$interface | Set-DnsClientServerAddress -ResetServerAddresses
}

Change DNS and IP Addresses Remotely on Multiple Computers with PowerShell

You can use PowerShell to remotely change the IP address or DNS server settings on multiple remote computers.

Suppose, your task is to change the DNS settings on all Windows Server hosts in the specific AD Organizational Unit (OU). The following script uses the Get-ADComputer cmdlet to get the list of computers from Active Directory and then connects to the remote computers through ?WinRM (the Invoke-Command cmdlet is used):

$Servers = Get-ADComputer -SearchBase ‘OU=Servers,OU=Berlin,OU=DE,DC=woshub,DC=cpm’ -Filter '(OperatingSystem -like "Windows Server*")' | Sort-Object Name
ForEach ($Server in $Servers) {
Write-Host "Server $($Server.Name)"
Invoke-Command -ComputerName $Server.Name -ScriptBlock {
$NewDnsServerSearchOrder = "192.168.2.11","8.8.8.8"
$Adapters = Get-WmiObject Win32_NetworkAdapterConfiguration | Where-Object {$_.DHCPEnabled -ne 'True' -and $_.DNSServerSearchOrder -ne $null}
Write-Host "Old DNS settings: "
$Adapters | ForEach-Object {$_.DNSServerSearchOrder}
$Adapters | ForEach-Object {$_.SetDNSServerSearchOrder($NewDnsServerSearchOrder)} | Out-Null
$Adapters = Get-WmiObject Win32_NetworkAdapterConfiguration | Where-Object {$_.DHCPEnabled -ne 'True' -and $_.DNSServerSearchOrder -ne $null}
Write-Host "New DNS settings: "
$Adapters | ForEach-Object {$_.DNSServerSearchOrder}
}
}
