<p>This Looking Glass provides you with information relative to backbone routing and network efficiency, providing you with the same transparency that customers on our network receive directly.</p>
<p>Traceroute allows a user to follow a packet through the network to a specific destination. It shows the domain, IP address and the roundtrip packet times as it traces the route to the destination.</p>
<p>Ping can be used to show whether or not a device with a valid Internet address or domain name can return packets sent to it by a specified server.</p>
