I don't know either, but have disabled ipv6 in "yast network" which says a reboot is required.
Odd that the connection worked with ipv6 enabled since late april when I changed provider until ~16 July and then just stopped. Anyway, disabling ipv6 will prove itself right or wrong. Will advise.
Not that odd, it is surely related. Maybe with the old provider you did not get the IPv6 address in the result list, or it was in a different order, so it was not tried, and you didn't see the problem...
Disabling IPv6 is a hack, not the real solution. It is bad. But it is the only thing we can do, because there is no global setting to disable DNS from getting IPv6 responses on Internet, when the provider doesn't give us an IPv6 connection.
/etc/gai.conf may be used to change precedence of IPv4 vs. IPv6; default it to favor IPv6. I run with IPv6 disabled since years (my provider does not offer IPv6 anyway) so I cannot test. I also am not sure whether this affects all glibc name resolution behavior or only specifically getaddrifo.
It also disables IPv6 in your entire machine. It can be used on local connections.
