20.04, netplan: no reverse lookups with traceroute

cn flag

I'm running an Ubuntu 20.04 server and if I do a traceroute to a server in my DMZ or the internet, I only see IPs.
But if I do an nslookup for those IPs I get hostnames, but it says that Authoritative answers can be found from: and then nothing. Even though /etc/netplan/00-installer-config.yaml points to the proper, authoritative, servers.

What am I doing wrong here?

Edit: I just noticed that traceroute6 displays proper hostnames while nslookup bevaves the same for IPv6.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
