I disagree with one thing: "The reason is that the use of link-local addresses for DNS resolvers is quite rare" I have seen a lot of such setups. (some LTE-Routers, fritzboxes without Unique Local Unicast and speedports) "For anchors and software probes, the measurement code will use whatever it finds in /etc/resolv.conf. So far, none of those contained link-local addresses." That will be changed tonight :-) Regards, Thomas -- There?s no place like ::1 Thomas Sch?fer (Systemverwaltung) Ludwig-Maximilians-Universit?t Centrum f?r Informations- und Sprachverarbeitung Oettingenstra?e 67 Raum C109 80538 M?nchen ? +49/89/2180-9706 ? +49/89/2180-9701
