Whatismyip.org shows you your external IP address. Unless your computer is connected directly to the internet (i.e. no router), any code you run that only looks at the local machine can only give your your internal address.

If you want to be sure to always get the external IP, you will have to use an external service like whatismyip.

As for changing that IP address, that is very dependent on the internet connection that is being used and how the IP address is obtained.

ooooooo...I seee!! oo... thx!! I been woundering That for The longest...But Would You No How To Use System.Net.Sockets To Find My external Ip
?

You can look your IP up this way;

Code:

---

    Public Function GetExternalIP() As String
        Dim IP_URL As String = "http://checkip.dyndns.org"
        Dim strHTML, strIP As String
        Try
            Dim objWebReq As System.Net.WebRequest = System.Net.WebRequest.Create(IP_URL)
            Dim objWebResp As System.Net.WebResponse = objWebReq.GetResponse()
            Dim strmResp As System.IO.Stream = objWebResp.GetResponseStream()
            Dim srResp As System.IO.StreamReader = New System.IO.StreamReader(strmResp, System.Text.Encoding.UTF8)
            strHTML = srResp.ReadToEnd()
            Dim regexIP As System.Text.RegularExpressions.Regex
            regexIP = New System.Text.RegularExpressions.Regex("\b\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}\b")
            strIP = regexIP.Match(strHTML).Value
            Return strIP
        Catch ex As Exception
            MessageBox.Show("Can't retrieve external IP: " & ex.Message)
            Return Nothing
        End Try
    End Function

Technically, you could use the webclient.DownloadString() on whatismyip.org to get the IP address. If you were looking to do this very frequently or for a lot of users, you should probably contact the web site to make sure they are OK with you doing that.

Code:

---

        Dim wc As New System.Net.WebClient()
        MessageBox.Show(wc.DownloadString("http://whatismyip.org"))

oo ok ...Ok So like Im Gonna Have a Textbox And a Button ANd Once I click The Button I want it To Like Show The Ip SO instead of "Messagebox.show"
Can I Put textbox1?...And Is there A Winsock Method
Because I Have winsock For Visual basic 2008 :)

I think what they are saying is that there may not be a Winsock method that will do this, but it depends on how you connect to the internet. If you are connecting over a LAN, or through a router (I make that distinction for a reason, but I won't go into it), then Winsock will give you the wrong IP address.

So before you go further, how are you connecting to the internet?

ooo By LAN...But Like I Im trying To Make A Ip program for Both..I just need sumone to like push me in the right direction on how to make it and stuff

Get you local IP using;

Code:

---


        'Using Imports System.Net.dns at the top of your file

        Dim IpAddr() As Net.IPAddress = GetHostEntry(GetHostName()).AddressList
        For i As Integer = 0 To IpAddr.Length - 1
            MessageBox.Show(IpAddr(i).ToString)
        Next

and your external IP in the way I showed in post #4.

thank you for the help i need help on the same thing
