Como obter o IP, mascara da sub-rede, gateway e servidor de dns ?
(No vb 2008 e ou 2010)


O IP já consegui, agora falta o resto
Imports System
Imports System.Net
Imports System.Net.Dns

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim sas As String = Dns.GetHostName()
       
   
        DoGetHostAddresses(sas)

    End Sub
    Public Sub DoGetHostAddresses(ByVal hostName As [String])

        Dim ips As IPAddress()

        Dim ns
        ips = Dns.GetHostAddresses(hostName)

               TextBox1.Text = ips(ips.Length - 1).ToString


    End Sub
End Class
