Problems with DNS resolution

i have a problem with DNS resolution. The routing seems to work, because I can ping other servers and traceroute also works. But using dig, i get the a address for 'a.root-servers.net not found error. I'm on opensuse leap 15.4. dig +trace google.de @1.1.1.1 ; > DiG 9.16.20 > +trace google.de @1.1.1.1 ;; global options: +cmd . 515724 IN NS a.root-servers.net. . 515724 IN NS b.root-servers.net. . 515724 IN NS c.root-servers.net. . 515724 IN NS d.root-servers.net. . 515724 IN NS e.root-servers.net. . 515724 IN NS f.root-servers.net. . 515724 IN NS g.root-servers.net. . 515724 IN NS h.root-servers.net. . 515724 IN NS i.root-servers.net. . 515724 IN NS j.root-servers.net. . 515724 IN NS k.root-servers.net. . 515724 IN NS l.root-servers.net. . 515724 IN NS m.root-servers.net. . 515724 IN RRSIG NS 8 0 518400 20230209050000 20230127040000 951 .
