Hi can some one help me with saving my WAN IP to a text file.
I am using a router so not even sure how VB is going to obtain the WAN IP.

Or even if your aware of the source code for this or some thing similar I would appreciate any help.

Connect to some www address that returns to you your IP address in HTML format.
Possible address is http://checkip.dyndns.org/index.html

Private Sub Form_Load()
    Dim IE, RET, POS1, POS2
    Set IE = CreateObject("internetexplorer.application")
        IE.navigate "http://www.whatismyip.com"
        While IE.busy: DoEvents: Wend
        RET = IE.document.Title
        IE.Quit
    Set IE = Nothing
    POS1 = InStr(1, RET, "is", vbTextCompare) + 3
    POS2 = InStr(1, RET, "what", vbTextCompare)
    Open "c:\wanip.txt" For Output As #1
        Print #1, Mid(RET, POS1, POS2 - (POS1 + 1))
