Nameserver Setup For Subdomain

I have a domain, flossnet.co.za which is pointing to a VPS at Contabo with nameservers ns1.flossnet.co.za and ns2.flossnet.co.za

I have created a subdomain, courses.flossnet.co.za which points to a VPS at A2 Hosting.

I have added in the web hosting control panel for courses.flossnet.co.za, the nameservers ns1.flossnet.co.za and ns2.flossnet.co.za

However, when checking the nameservers for courses.flossnet.co.za with whatsmydns, it does not show any nameserver.

Any idea how one fixes it?

Tell us the real names so we can check. Don't hide DNS names when you ask about DNS.

+100 to @vidarlo comment and also just ask your "provider A" and "provider B" for help if you can't set up things correctly. The best online troubleshooting tool to use if you want to do it yourself (which you have to until you disclose real names involved) is DNSViz. Fix any errors it reports.

@vidarlo, I have rephrased the question.

Your server doesn't return any NS records. Show your zone file.

I have created a subdomain, courses.flossnet.co.za which points to a VPS at A2 Hosting.

Yes, you have created a A record that points to 190.92.190.225. That doesn't do anything but create an A-record.

If you want to hand control of courses.flossnet.co.za to another nameserver, you have to create a NS record to provide a delegation:

courses IN NS ns1.courses; Delegation record
ns1.courses IN A 190.92.190.225; Glue record

This way you delegate control of courses.flozznet.co.za to ns1.courses.flozznet.co.za and provide an IP for this.

These records has to be created in the flozznet.co.za zone.

You would then of course have to configure the namserver running on you VPS accordingly.

Note that delegation is only required if you want ns1 in this example to be able to add names on its own.

@vidario, I have added the zone file for courses.flossnet.co.za.db above.

Those two records should go into the `flossnet.co.za` zone.

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.
