 #Here is a quick way to get all IP addresses assigned to your #computer:
#requires -Version
$ipaddress = [System.Net.DNS]::GetHostByName($null)
Foreach ($ip in $ipaddress.AddressList)
If you replace $null with a hostname (like "server123"), you can retrieve the IP address(es) assigned to that computer instead, too.
#And if you are just interested in IPv4 addresses, try this:
#requires -Version
$ipaddress = [System.Net.DNS]::GetHostByName($null)
foreach($ip in $ipaddress.AddressList)
if ($ip.AddressFamily -eq 'InterNetwork')
