    <p>Given that I had to write a TraceRoute class today I figured I might as well share the source code.</p> <pre><code>using System.Collections.Generic; using System.Net.NetworkInformation; using System.Text; using System.Net; namespace Answer { public class TraceRoute { private const string Data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"; public static IEnumerable&lt;IPAddress&gt; GetTraceRoute(string hostNameOrAddress) { return GetTraceRoute(hostNameOrAddress, 1); } private static IEnumerable&lt;IPAddress&gt; GetTraceRoute(string hostNameOrAddress, int ttl) { Ping pinger = new Ping(); PingOptions pingerOptions = new PingOptions(ttl, true); int timeout = 10000; byte[] buffer = Encoding.ASCII.GetBytes(Data); PingReply reply = default(PingReply); reply = pinger.Send(hostNameOrAddress, timeout, buffer, pingerOptions); List&lt;IPAddress&gt; result = new List&lt;IPAddress&gt;(); if (reply.Status == IPStatus.Success) { result.Add(reply.Address); } else if (reply.Status == IPStatus.TtlExpired || reply.Status == IPStatus.TimedOut) { //add the currently returned address if an address was found with this TTL if (reply.Status == IPStatus.TtlExpired) result.Add(reply.Address); //recurse to get the next address... IEnumerable&lt;IPAddress&gt; tempResult = default(IEnumerable&lt;IPAddress&gt;); tempResult = GetTraceRoute(hostNameOrAddress, ttl + 1); result.AddRange(tempResult); } else { //failure } return result; } } } </code></pre> <p>And a VB version for anyone that wants/needs it</p> <pre><code>Public Class TraceRoute Private Const Data As String = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" Public Shared Function GetTraceRoute(ByVal hostNameOrAddress As String) As IEnumerable(Of IPAddress) Return GetTraceRoute(hostNameOrAddress, 1) End Function Private Shared Function GetTraceRoute(ByVal hostNameOrAddress As String, ByVal ttl As Integer) As IEnumerable(Of IPAddress) Dim pinger As Ping = New Ping Dim pingerOptions As PingOptions = New PingOptions(ttl, True) Dim timeout As Integer = 10000 Dim buffer() As Byte = Encoding.ASCII.GetBytes(Data) Dim reply As PingReply reply = pinger.Send(hostNameOrAddress, timeout, buffer, pingerOptions) Dim result As List(Of IPAddress) = New List(Of IPAddress) If reply.Status = IPStatus.Success Then result.Add(reply.Address) ElseIf reply.Status = IPStatus.TtlExpired Then 'add the currently returned address result.Add(reply.Address) 'recurse to get the next address...

    1. COCool solution. Minor point but since you used an IEnumerable<> return, you might consider doing yield return instead of populating the list.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
