I am trying to check availability of an IoTHub using Ping,

public async Task<bool> CheckAvailabilityAsync(string url)
{
    if (string.IsNullOrEmpty(url)) return false;
    Ping ping = new Ping();
    try
    {
        var result = await ping.SendPingAsync(url);
        return result.Status == IPStatus.Success;
    }
    catch (Exception ex)
    {
        return false;
    }
}

here url is “notavilableiothubName.azure-devices.net”.
look like ICMP is not supported for outbound ! What is the best way to achieve this ! Is there a native availability check for iothubs?
