Beginning with Windows 8 and Server 2012, operating systems ship with extensive PowerShell modules to manage server and client. They provide cmdlets like Get-NetIPAddress.
If you’d like to get a list of all IP addresses originating from DHCP, you could try this:
#requires -Version 3.0 -Modules NetTCPIP Get-NetIPAddress | Where-Object PrefixOrigin -eq dhcp | Select-Object -ExpandProperty IPAddress
