How can I create a datatable from a website?

Shared Async Function LoadMap() As Task(Of DataTable)
    Const url As String = "https://gitlab.com/wireshark/wireshark/raw/master/manuf"
    
    Dim result As New DataTable()
    result.Columns.Add("MacAddress", GetType(String))
    result.Columns.Add("Manufacturer", GetType(String))
    
    Dim http As New HttpClient()
    Using response As HttpResponseMessage = Await http.GetAsync(url)
        response.EnsureSuccessStatusCode()
        
        Using stream As Stream = Await response.Content.ReadAsStreamAsync()
            Using reader As New StreamReader(stream)
                Dim line As String = reader.ReadLine()
                While line IsNot Nothing
                    If line.Length <> 0 AndAlso line(0) <> "#"c Then
                        Dim parts As String() = line.Split(Microsoft.VisualBasic.Constants.vbTab)
                        result.Rows.Add(parts(0), parts(1))
                    End If
                    
                    line = reader.ReadLine()
                End While
            End Using
        End Using
    End Using
    
    Return result
End Function
