I have a Tumbleweed box utilizing NetworkManager and the default installation does not list*any* DNS servers, and correctly connects utilizing ipv6. you do not want to utilize the "default" setting but specify your own. why do you think that NetworkManager should know this w/o you specifically setting those desired sites?
Resolv.conf lists the DNS server(s) available. On my desktop computer, that info is from a static configuration in Yast. However, when network manager is used, those servers are supposed to be added automatically, through DHCP, DHCPv6 or RDNSS. On every other device I use, an IPv6 address for the DNS server is used, except for my notebook computer, when running Leap 15.4. That same computer uses the IPv6 address when running Windows. So, clearly the issue is with the network manager on Leap 15.4 and earlier versions. I have verified this by doing packet captures on my pfSense firewall/router. BTW, I was first aware of this issue 12 years ago, with RDNSS and as of yesterday with DHCPv6. Also, a Windows 10 VM running on this computer uses IPv6, while Leap uses IPv4.
