If so, it's > always nicer to reuse existing data :-) The idea here is - I have a host in a "home network" that has 2 ISPs, with a global IPv6 address from each of them - one of the ISPs fails, but the host does not know, and keeps using the "broken" IPv6 source address - by cyclic measurements, Brian's tool will see "nah, that address stopped working" and will de-preference it on the host -> host starts using the other IPv6 source address -> connectivity restored (over the other ISP) and the test envisioned would be "ping something willing to be pinged" :-) Gert Doering -- NetMaster -- have you enabled IPv6 on something today...?
