Configuring IP addressing

By default, Windows uses DHCP to configure any NICs that are found during the installation process. Once you complete the installation of Windows, you can use the settings application netsh.exe, or, of course, PowerShell to set IP configuration manually.

Getting ready

This recipe runs on SRV2.Reskit.Org. This host is a domain-joined system with an NIC that is initially set up to be configured from DHCP.

How to do it...

1. Get existing IP address information for SRV2:

   $IPType = 'IPv4'
   $Adapter = Get-NetAdapter |
     Where-Object Status -eq 'Up'    
   $Interface = $Adapter |
     Get-NetIPInterface -AddressFamily $IPType
   $IfIndex = $Interface.ifIndex
   $IfAlias = $Interface.Interfacealias
   Get-NetIPAddress -InterfaceIndex $Ifindex -AddressFamily $IPType

2. Set the IP address for SRV2:

   $IPHT = @{
     InterfaceAlias = $IfAlias
     PrefixLength   = 24
     IPAddress      = '10.10.10.51'
     DefaultGateway = '10.10.10.254'
     AddressFamily  = $IPType
   }
