@dogo ok, i recommend to lookup ipv4 & ipv6 dns servers as a temporary solution... and then calling the isp (today if possible) or tomorrow and asking them wtf is going on... oh and yes, if you wana avoid an awkward situation you might wana lookup for a random webpage which have ipv6 which is not in your cache... i always use local news papers or public media which i usually not read for such things
