Capture multiline, multi-group to Powershell variables

Question

Ideally, I would like to create an object from ipconfig that allows us to drilldown to each adapter\'s attributes like this: $ip.$lan.$mac for the lan adapter\'s mac address

Answer 1

I know this doesn't directly answer your question. But rather than parsing the output of ipconfig with Regex. You could instead use Get-NetIPConfiguration to get a powershell object that is easier to deal with.

PS> $ip = Get-NetIPConfiguration
PS> $ip

InterfaceAlias       : Ethernet
InterfaceIndex       : 12
InterfaceDescription : Intel(R) Ethernet Connection I217-LM
NetProfile.Name      : xyz.com
IPv4Address          : 10.20.102.162
IPv6DefaultGateway   :
IPv4DefaultGateway   : 10.20.102.1
DNSServer            : 10.20.100.9
                       10.20.100.11
                       10.20.100.13

PS> $ip.IPv4Address

IPAddress         : 10.20.102.162
InterfaceIndex    : 12
InterfaceAlias    : Ethernet
AddressFamily     : IPv4
Type              : Unicast
PrefixLength      : 23
PrefixOrigin      : Dhcp
SuffixOrigin      : Dhcp
AddressState      : Preferred
ValidLifetime     : 05:16:53
PreferredLifetime : 05:16:53
SkipAsSource      : False
PolicyStore       : ActiveStore
PSComputerName    :

Thus you can do the following to get the values you are looking to acquire.

$ip.InterfaceAlias
$ip.InterfaceDescription
$ip.IPv4Address.IPAddress

To get the MAC the address you can use the Get-NetAdapter cmdlet.

$adapter = Get-NetAdapter
$adapter.MacAddress

You can correlate the two pieces of information using the InterfaceIndex. Then return a hashtable that makes each accessible. The following creates an array of these combined objects.

$combined = Get-NetIPConfiguration | ForEach-Object {
    $adapter = Get-NetAdapter -InterfaceIndex $_.InterfaceIndex
    @{ IP = $_; Adapter = $adapter }
}
