2.19.3.2. tracert/traceroute

Asterisks instead of values next to intermediate nodes do not always mean that those nodes are unreachable or faulty. Usually, it is simply a configuration on the node that prevents it from sending ICMP response messages. If the request has reached the endpoint safely in a reasonable amount of time, there is nothing to worry about.

tracert/traceroute is a standard utility that can be used to check the status of intermediate nodes on the network route to a site and to determine the network section that is malfunctioning if the site is unavailable. Depending on the operating system used, it uses ICMP or UDP protocol.
