nslookup not retrieving authoritative answer

in flag

I'm trying to get an authoritative answer using nslookup but it's not working

$nslookup animeflv.net matt.ns.cloudflare.com

Server:  matt.ns.cloudflare.com
Address:  108.162.193.131#53

Non-authoritative answer:
Name:    animeflv.net
Address:  172.67.70.233
Name:    animeflv.net
Address:  104.26.0.100
Name:    animeflv.net
Address:  104.26.1.100

Why? Is it cache, the router? How can I query matt.ns.cloudflare.com?

I get an authoritative answer running the same query from my machine. Do you have anything that might be intercepting external DNS queries?

Do you get same behavior if you query `2606:4700:58::adf5:3b83#53` (which is `matt.ns.cloudflare.com` IPv6 address)? The answer is correct, but something may alter the DNS packets. `dig @matt.ns.cloudflare.com animeflv.net | grep flags` shows `;; flags: qr aa rd; QUERY: 1, ANSWER: 3, AUTHORITY: 0, ADDITIONAL: 1`

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer.

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.
