Resolve a Hostname to an IP Address

Demonstrates Socket.DnsLookup, which resolves a hostname and returns one numeric IP address.

Background. A maxWaitMs of 0 waits indefinitely; a positive value bounds the wait. Resolved results may be served from Chilkat's process-wide DNS cache.

Dim socket As New Chilkat.Socket

'  Resolve a hostname to a numeric IP address, waiting up to 5 seconds.
Dim ipAddress As String = socket.DnsLookup("example.com",5000)
If (socket.LastMethodSuccess = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If

Debug.WriteLine("Resolved IP address: " & ipAddress)
