  in socket programming one might need to get ones own IP address.
  for that use Sockets namespace .
  The function : GetHostEntry will help u out.

  if i am not mistaken then sanket u want to know how to send files across network.
  
  for that sanket you need 2 main things
  
  1) an instance of a file stream to send files across
  
  2) an array of bytes because u need to store all the data u want to sed in the form of bytes.

  Check this code for getting IP address
  
  Imports System.Net
  Public Class CGetLocalIPAddress
  Dim sIpAddr As String
  'Dim myLocalIP As New CGetLocalIPAddress
  Public Sub New()
  GetLocalIPAddress()
  End Sub
  Private Sub GetLocalIPAddress()
  Dim ipEntry As IPHostEntry = Dns.GetHostByName(Environment.MachineName)
  Dim mIpAddr As IPAddress() = ipEntry.AddressList
  Dim i As Integer
  sIpAddr = mIpAddr(1).ToString()
  End Sub
  Public Property LocalIPAddress() As String
  Get
  Return sIpAddr
  End Get
  Set(ByVal Value As String)
  sIpAddr = Value
  End Set
  End Property
  End Class
