<br />the number of routers between the source and destination device<br />
<br />the IP address of the router nearest the destination device<br />
<br />***the average time it takes a packet to reach the destination and for the response to return to the source<br />
<br />***whether or not the destination device is reachable through the network<br />
<br />the average time it takes each router in the path between source and destination to respond<br />
