Traceroute Disclaimer
Traceroute is a tool which is useful for determining the route taken by packets across an IPv6 or IPv4 network. But traceroute is not a tool that should be used to test network performance. There are a number of other tools better suited to evaluate network performance. One tool that NTT Communications recommends for this purpose is iperf.
Also note that some instances of executing traceroute can take minutes to complete. This is especially true if there is a firewall, ACL, or some other mechanism blocking traceroute packets to/from the destination you are trying to test. Traceroute packets that do not return within the timeout period, usually because they are being blocked as noted above, will show up in the final results as an asterisk (*). Note, this is not a deficiency of our tool or network, it is caused by circumstances beyond NTT Communications' control.
