[keeping the wide variety of potential IPv6 node behavior in mind] that said I concur with the approach laid out in an earlier mail by Philip: "RIPE Atlas acts as a connectivity observatory. A ULA is the equivalent of an unconnected node. It is not broken; it is, by design, limited to local connectivity, and should always be that way. If a device has no global IPv6 address, it should be regarded as IPv6 incapable, not IPv6 broken." best Enno -- Enno Rey ERNW GmbH - Carl-Bosch-Str. 4 - 69115 Heidelberg - www.ernw.de Tel. +49 6221 480390 - Fax 6221 419008 - Cell +49 173 6745902 Handelsregister Mannheim: HRB 337135 Geschaeftsfuehrer: Enno Rey ======================================================= Blog: www.insinuator.net || Conference: www.troopers.de Twitter: @Enno_Insinuator =======================================================
