Config NIC with static IP

$IP = "172.29.106.41"
$MaskBits = 27 # 24 = 255.255.255.0 | 27 = 255.255.255.224 $Gateway = "172.29.106.62" $Dns = "172.29.10.69" $IPType = "IPv4"

Retrieve the network adapter that you want to configure

$adapter = Get-NetAdapter | ? {$_.Status -eq "up"}

Remove any existing IP, gateway from our ipv4 adapter

If (($adapter | Get-NetIPConfiguration).IPv4Address.IPAddress) { $adapter | Remove-NetIPAddress -AddressFamily $IPType -Confirm:$false }
If (($adapter | Get-NetIPConfiguration).Ipv4DefaultGateway) { $adapter | Remove-NetRoute -AddressFamily $IPType -Confirm:$false }

Configure the IP address and default gateway

$adapter | New-NetIPAddress ` -AddressFamily $IPType ` -IPAddress $IP ` -PrefixLength $MaskBits ` -DefaultGateway $Gateway

Configure the DNS client server IP addresses

$adapter | Set-DnsClientServerAddress -ServerAddresses $DNS
