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

Question

How can i get ip address of system by sending mac ip address as input using vb.net coding?

Answer 1

Shows the Computer Name, Use a Button to call it

Dim strHostName As String

    strHostName = System.Net.Dns.GetHostName().

    MsgBox(strHostName)

Shows the User Name, Use a Button to call it

If TypeOf My.User.CurrentPrincipal Is Security.Principal.WindowsPrincipal Then

        Dim parts() As String = Split(My.User.Name, "\")

        Dim username As String = parts(1)

        MsgBox(username)

   End If

For IP Address its little complicated, But I try to explain as much as I can. First write the next code, before Form1_Load but after import section

Public Class Form1

Dim mem As String

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()

    mem = strIPAddress
    MessageBox.Show("IP Address: " & strIPAddress)

End Sub

Then in Form1_Load Section just call it

GetIPAddress()

Result: On form load it will show a msgbox along with the IP address, for put into Label1.text or some where else play with the code.
