...and when you are trying to debug AS112 stuff you normally also want to try to run this: --snip # dig +short txt hostname.as112.arpa "Unique IP: 22.214.171.124 / 2001:7f8:24::fa" "See http://as112.net/ for more information." "AS112 at SwissIX, http://www.swissix.ch, Zurich, Switzerland" --snap This will surface the name of the node you are ending up with. Running a traceroute will probably not help so much because, as you already correctly stated, this is an anycasted ip-address. It may point you into the right direction, but it might as well misguide you. -- s w i s s i x - Swiss Internet Exchange Roman Hochuli Board Member _______________________________________________ swinog mailing list email@example.com http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
