Hi, We run 6to4 and Teredo relay routers and in order to monitor the service our network monitoring system has been pinging a handful of 6to4 and Teredo addresses elsewhere. If more than one of those addresses fail to answer pings, an alarm is raised. Now I'm looking for a few more addresses I could ping, so I could raise the alert threshold a bit. Any volunteers? And in case anyone else wants to ping some of our hosts, here's a couple of candidates: (sorry, no Teredo hosts) ns.trex.fi. IN AAAA 2002:c38c:c38c:15::35 mail.trex.fi. IN AAAA 2002:c38c:c38c:14:203:baff:fe0f:d68b Yours sincerely, -- Aleksi Suhonen / TREX
