How do you choose the fastest server from a DNS?

Public Class SocketMaster
 
    Public Event OnConnect()
    Public Event OnDisconnect()
    Public Event OnError(ByVal Err As SocketException)
 
    Private Socket As Socket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
 
    Public Sub Connect(ByVal server As String, ByVal port As Integer)
        Dim hostEntry As IPHostEntry = Nothing
        Dim address As IPAddress
        Try
            hostEntry = Dns.Resolve(server)
            For Each address In hostEntry.AddressList
                Dim endPoint As New IPEndPoint(address, port)
                Socket = New Socket(endPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp)
                Try
                    Socket.Connect(endPoint)
                    If Socket.Connected = True Then
                        RaiseEvent OnConnect()
                        Exit For
                    End If
                Catch Err As SocketException
                    RaiseEvent OnError(Err)
                End Try
            Next address
        Catch Err As SocketException
            RaiseEvent OnError(Err)
        End Try
    End Sub
 
    Public Sub Disconnect()
        Try
            Socket.Close()
            RaiseEvent OnDisconnect()
        Catch Err As SocketException
            RaiseEvent OnError(Err)
        End Try
    End Sub
 
End Class

This is my socket class

When you DNS like www.google.com and it gives you a list of address's, i want to ping each one to find the fastest, however i am unsure of how to do this.
