How do I get a computer's name and IP address using VB.NET?

Use the My Class :)

My.Computer.Name

as for the IP address quick google search

Private Sub GetIPAddress()

Dim strHostName As String

Dim strIPAddress As String



strHostName = System.Net.Dns.GetHostName()

strIPAddress = System.Net.Dns.GetHostByName(strHostName).AddressList(0).ToString()


MessageBox.Show("Host Name: " & strHostName & "; IP Address: " & strIPAddress)

End Sub

Private Function GetIPv4Address() As String
    GetIPv4Address = String.Empty
    Dim strHostName As String = System.Net.Dns.GetHostName()
    Dim iphe As System.Net.IPHostEntry = System.Net.Dns.GetHostEntry(strHostName)

    For Each ipheal As System.Net.IPAddress In iphe.AddressList
        If ipheal.AddressFamily = System.Net.Sockets.AddressFamily.InterNetwork Then
            GetIPv4Address = ipheal.ToString()
        End If
    Next

End Function

Here is Example for this. In this example we can get IP address of our given host name.

   Dim strHostName As String = "jayeshsorathia.blogspot.com"
    'string strHostName = "www.microsoft.com";
    ' Get DNS entry of specified host name
    Dim addresses As IPAddress() = Dns.GetHostEntry(strHostName).AddressList

    ' The DNS entry may contains more than one IP addresses.
    ' Iterate them and display each along with the type of address (AddressFamily).
    For Each address As IPAddress In addresses
        Response.Write(String.Format("{0} = {1} ({2})", strHostName, address, address.AddressFamily))
        Response.Write("<br/><br/>")
    Next
