Getting a Users External IP Address

It was a pain in the butt to get the users external IP alone and return it to the user, so I made this:

Code:

---

Imports System.Net
Imports System.Text.RegularExpressions

Public Class Form1

    Dim ip As String = ""

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim web As New WebClient
        Dim fullstringip As String = web.DownloadString("http://whatismyipaddress.com/")
        Dim ipRegex As New System.Text.RegularExpressions.Regex("<a href=""//whatismyipaddress.com/ip/.*"" style=""")
        Dim matches As MatchCollection = ipRegex.Matches(fullstringip)
        For Each matchfound In matches
            Dim dirtyip As String = matchfound.ToString.Replace("<a href=""//whatismyipaddress.com/ip/", "")
            ip = dirtyip.Replace(""" style=""", "")
        Next
        MsgBox(ip) '<This is the final code with a messagebox to show the users IP.
    End Sub
End Class

It's easy and it works.
Enjoy!

Thats not a very element piece of code. Have you got permission from the site?
