Hi, i used to get external ip address from "http://automation.whatismyip.com/n09230945.asp"

but it's no longer "free", so, anyway to get external ip address on string?
Thanks.

Well, there are a few sites that will give you your IP address, one is here.

Or, you could play around with this code.

    Private Sub GetIPAddr()
        Dim hostName As String
        Dim ipAddr() As IPAddress

        hostName = System.Net.Dns.GetHostName()
        ipAddr = Dns.GetHostAddresses(hostName)

        For i = 0 To ipAddr.Count - 1
            Debug.Print(CStr(i) & " " & ipAddr(i).ToString)
        Next
    End Sub

This gives a number of IP addresses. In my case entry 2 is my external IP address (in Hexadecimal), and entries 3 and 4 are internal (LAN) addresses (in Decimal).

Thanks, it works with that site.

Appreciated.

This gives you one address - you just have to carve it out of the string given.

Using wb As New WebClient
      Dim s As String = wb.DownloadString("http://www.whatsmyip.us/showipsimple.php")
      MessageBox.Show(s)
End Using

Result = document.write("33.223.445.23")

Full script here.

i believe lar3ry's code will only return the local ip. You're most likely looking for the external/public ip. I highly recommend you just hook it up to your own php script and get the ip with that.

<?php
$ipaddress = $_SERVER["REMOTE_ADDR"];
echo $ipaddress
?>

will get and return the ip address as a string. Or, if you're getting the ip address for security, make a php script for logging in and then just simply have it also record the ip address of the person logging in and their username.

But, if you're using it for something else that doesn't require it to be recorded on the server, then simply use that code with your own php file and use regex to extract it.

Actually, it returns all the IP addresses associated with the hostname supplied as a string. As I mentioned, the local (LAN) IP and the external (WAN) IP are both returned.

I am interested in your script, though. I am not at all familiar with PHP, and my first question would be to ask how one invokes a PHP script, with or without VB.Net.

I wasn't familiar with it either until about a week ago xD anyways, what i'd do is write:

Imports System.Net
Imports System.IO
Imports System.Text.RegularExpressions

Dim req As httpwebrequest = httpwebrequest.create("MyDomain.com/checkIp.php")
req.Method = "GET"

Dim response At Httpwebresponse = DirectCast(req.GetResponse(), Httpwebresponse)
Dim readBackData As String = New StreamReader(response.GetResponseStream()).ReadToEnd

Then carve it out in some regex.

And what's that have to do with the php function above post? Is that how it's used?

The php above is the code you'd store at: "MyDomain.com/checkIp.php". Then you carve out the echo'd response using regex.

If you have a website, create a php file with just this in it:

<?php echo  $_SERVER["REMOTE_ADDR"]; ?>

Sample on my site: http://www.gunnerinc.com/2.php (this won't be left there long, don't want my server to get hammered) just request that file with HTTP/sockets code and you will get your external IP returned.

congrats on replying with exactly what i said.

Hmm, i might try that, when u said "more security" it made me think, how can i do the same for sending mails from that application? Like store my username and password there?

Could i get an example please?
Thank you.

[LilGhost]

i do NOT recommend storing your own email credentials even in an obfuscated program.

I'd much rather see you just appending text to a file on your server.

On your server's php logging file you'd write:

$ipaddress = $_SERVER["REMOTE_ADDR"];
$logfile= 'accessed.txt';
$msg = $ipaddress . "\n";
$fp = fopen($logfile, 'a');
fwrite($fp, $msg);
fclose($fp);

[HeBTeMy]

I'm sorry, i don't understand really nothing of php, could you explain that code?
Where would my credentials be stored? In that .txt file?
I know that is not safe to store in an application, to easy to decompile, that's why i ask.

If there isn't much troble for you to explain me i would appreciate it.
Thanks.
