Almost two weeks ago, I set A and NS records on Cloudflare.

 A record: "tns" as the name and "IPV4 "as the content of the server.
 NS record: "t" as name and for content "tns.qawqa.link"

I set these records in this way to perform dnstt-deploy. However, it seems that the DNS has not been set yet. When I check it on https://dnschecker.org/#A/t.qawqa.link, only one country shows a green check, and when I use the nslookup command, this is the result:

nslookup t.qawqa.link
Server:  UnKnown
Address:  10.18.115.50

*** UnKnown can't find t.example.com: Non-existent domain

What should I do to set DNS?

    You're unlikely to get any useful answers from this. Your real domain isn't shown so pretty much all that can be suggested is, "ask Cloudflare" Commented Sep 19 at 15:53

    What A and NS records did you set? The best thing would still to be that you ask Cloudflare Commented Sep 20 at 9:41

    Is the server that you listed in the NS record actually a DNS server? Or only a web server? Commented Sep 20 at 11:23

The reason is that tns.qawqa.link is not a DNS server or does not know about t.qawqa.link, as shown below. Please note that I have used the server tns.qawqa.link specifically to give out the IP of t.qawqa.link.

$ nslookup t.qawqa.link tns.qawqa.link
Server:         tns.qawqa.link
Address:        20.150.193.11#53

** server can't find t.qawqa.link: NXDOMAIN

When you set an NS record, you are setting an authoritative DNS resolver for your domain. For example, here you have set tns.qawqa.link as the DNS resolver for t.qawqa.link. Therefore, when any device queries for the IP of t.qawqa.link, this question will be asked from tns.qawqa.link.

  1. Please make sure to correct your question here by adding the information of tns.qawqa.link to it, rather than responding to it in the comments.
  2. Are you sure you want to define an authoritative name server for t.qawqa.link? If not, then what is this name server record supposed to do?
  3. checkdns.org is non-existent. Did you mean dnschecker.org? You could have put the whole link https://dnschecker.org/#A/t.qawqa.link to make it easier for the readers.
