Thank you in advance for any and all comments and help.

I have an application that an Administrator might use. I'm trying to figure
out how to programatically get the local Machine LAN IP addres. Using VB.NET
2005.

Net.Dns.GetHostByName(Net.Dns.GetHostName).AddressList.GetValue(0)

that will return an IPAddress object of the local computer in terms of the
LAN IPAdress of the computer

Thank you for a quick reply, but when I attempt to use the code you supplied
I get all kinds of errors saying sytax is obsolete and use xxxxx etc

Use GetHostEntry:

Net.Dns.GetHostEntry(Net.Dns.GetHostName).AddressList.GetValue(0).ToString

for VB 2005 its

Net.DNS.GetHostEntry(Net.Dns.GetHostName()).AddressList.GetValue(0)

that should work

iwdu15,

I was able to find a post by your and get the code. in .NET 2005, some API's
have changed and the code you gave me did not work, but I did get if figured
out. Thank you for the heads up. Now I'm trying to find a way to get the
router IP address programatically. :)

        Dim HostIP As IPAddress
        HostIP = Dns.GetHostEntry(Dns.GetHostName).AddressList.GetValue(0)
        Label1.Text = HostIP.ToString

the change was subtle but notice the GetHostEntry!

hello Michael,

Are you using VB 2005 when testing the code? Also, what's the detailed
syntax error and which method is the compiler recommending you to use?

Here are the two code fragment that works correct in my VB 2005 console
application:

===============
For Each ip As System.Net.IPAddress In
System.Net.Dns.GetHostAddresses(System.Net.Dns.GetHostName())

            Console.WriteLine( ip.ToString())
        Next

        For Each ip As System.Net.IPAddress In
System.Net.Dns.GetHostEntry(Net.Dns.GetHostName()).AddressList
            Console.WriteLine(ip.ToString())
        Next
=======================

Hope this helps.

Sincerely,

Steven Cheng

Steven,

Thank you for your reply. I was able to find the answer in a previous post
to correct the API change in .NET 2.0.
