mtr ? - http://www.bitwizard.nl/mtr/
FWIW, Mtr measures latency/delay and loss based on ICMP messages heard
back from the routers on path. As a result, in almost all cases, the
real hop-by-hop latency of actual end-to-end data packets is better
than it can report.

For example, Netscreens cannot presently filter IPv6 in transparent

roadmap but over a year away.
