In this section, we are going to configure both a private and a public IP address. When we created the VNet, a private IP address was created for us automatically by Azure. However, we are going to create another in this demonstration and associate it, along with the public IP address, to a network interface card (NIC). To configure a private and public IP address from PowerShell, you have to perform the following steps:

1. In the same PowerShell window, add the following code to retrieve the VNet and subnet configuration:

$vnet = Get-AzVirtualNetwork -Name PacktVirtualNetwork -ResourceGroupName PacktVNetResourceGroup
$subnet = Get-AzVirtualNetworkSubnetConfig -Name default -VirtualNetwork $vnet

2. Next, create a private and a public IP address and assign them to the configuration, as follows:

$publicIP = New-AzPublicIpAddress `
    -Name PacktPublicIP `
    -ResourceGroupName PacktVNetResourceGroup `
    -AllocationMethod Dynamic `
    -Location EastUS

$IpConfig = New-AzNetworkInterfaceIpConfig `
  -Name PacktPrivateIP `
  -Subnet $subnet `
  -PrivateIpAddress 10.0.0.4 `
  -PublicIPAddress $publicIP `
  -Primary

3. Then, create a network interface and assign the configuration to it, as follows:

$NIC = New-AzNetworkInterface `
 -Name PacktNIC `
 -ResourceGroupName PacktVNetResourceGroup `
 -Location EastUS `
 -IpConfiguration $IpConfig

Now, we have configured an NIC, a public and a private IP address, and associated them with the VNet that we created in the previous section.
