I found a way to get the ipv4 address when there is only 1 adapter enabled. 

<pre><code class="code-1 nolinks" id="code-123205"> Try
 If My.Computer.Info.OSFullName.Contains(&quot;XP&quot;) Then
 strIPAddress = System.Net.Dns.GetHostAddresses(My.Computer.Name)(0).ToString
 Else
 strIPAddress = System.Net.Dns.GetHostAddresses(My.Computer.Name)(1).ToString
 End If
 Catch
 MsgBox(&quot;Unable to Return your IP Address&quot;, MsgBoxStyle.Critical)
 End Try
</code></pre>
</div>

I need to be able to show the local computers ipv4 Ip address on xp and vista. At the moment i am using : 
 
strIPAddress = System.Net.Dns.GetHostEntry(strHostName).AddressList(0).ToString() 
 
but this returns the ipv6 address in vista... any ideas? I was thinking of doing something like: 
 
if xp then 
&nbsp; &nbsp; strIPAddress = System.Net.Dns.GetHostEntry(strHostName).AddressList(0).ToString() 
else if vista 
&nbsp; &nbsp;whatever i need to do to get the vista address 
else 
&nbsp; &nbsp;strIPAddress = &quot;Unknown Operating system&quot; 
end if 
 
(very simplified version of course)

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.

Windows Vista is an operating system created by Microsoft as the successor to Windows XP. It was intended for PCs, workstations and laptops, and shares the same code base as its successor, Windows 7. New features included an updated graphical user interface (GUI) and visual style dubbed Aero, a new search component called Windows Search, redesigned networking, audio, print and display subsystems, and new multimedia tools. Vista aimed to increase the level of communication between machines on a home network, using peer-to-peer technology to simplify sharing files and media between computers and devices. Windows Vista included version 3.0 of the .NET Framework, allowing software developers to write applications without traditional Windows APIs.
