I'm attempting to figure out how/why my reverse DNS delegation is broken. I've already deleted systemd-resolved's temporary resolv.conf and added in an immutable single line nameserver 1.1.1.1 resolv.conf.
I can dig +trace forward hostnames fine. I cannot dig -x an ip +trace. All I get is the root-servers instead of any sort of reverse looking up happening at all. What am I doing wrong? Thanks, Mike $ dig -x 208.x.x.x +trace ; <<>> DiG 9.18.1-1ubuntu1.1-Ubuntu <<>> -x 208.x.x.x +trace ;; global options: +cmd . 509855 IN NS a.root-servers.net. . 509855 IN NS b.root-servers.net. . 509855 IN NS c.root-servers.net. . 509855 IN NS d.root-servers.net. . 509855 IN NS e.root-servers.net. . 509855 IN NS f.root-servers.net. . 509855 IN NS g.root-servers.net. . 509855 IN NS h.root-servers.net. . 509855 IN NS i.root-servers.net. . 509855 IN NS j.root-servers.net. . 509855 IN NS k.root-servers.net. . 509855 IN NS l.root-servers.net. . 509855 IN NS m.root-servers.net. . 509855 IN RRSIG NS 8 0 518400 20221012170000 20220929160000 20826 .
