List all IP addresses

I am trying to get all IP addresses on a vm and the associated portgroup.

$vm.Guest.IPAddress

I have the Vlan

$vmvlan = Get-VirtualPortgroup -VM $_.Name | %{$_.VlanId}

Now if there are more than 1 Vlan I can get it like this

$vmvlan[0]

$vmvlan[1]

Does anyone know how can I do the same for the IP addresses?
