How to set up one NS records for multiple domains?

Question

Domain Name System

Hello.
Can't set up the same NS records for multiple domains?
There is an example.com domain, NS records have been created for it

• ns1.example.com
  
• ns2.example.com
  

and A-records for the domain example.com and *.example.com, with the value of the IP of the server (this domain works without problems).
There are a few more domains for which I would like to have A-records from example.com.
If these domains, ns1.example.com and ns2.example.com, are specified in the NS records, they will not resolve to this ip.

;; connection timed out; no servers could be reached

As a result, you need NS records from one domain with the specified A records so that they work on other domains.
Thank you.

Answer 1

It's not clear what you want to do? And the record indicates the IP hosting on which your site is marked up. If you want your site to be opened by several domain names, then for each domain, write A records to the same IP.

Answer 2

You don't seem to understand how DNS works. You can read here and here
NS record for a domain indicates on which dns server information about this particular zone is stored.
In your case, obviously on the dns server where ns1.example.com points there is no information about the example2.com domain.
If you manage the ns1.example.com DNS server yourself, create an example2.com zone there.

It seems to me that you have a mess in your head ... Let's
say NS is the repository in which CN A MX records are stored, etc.
Here you have several domains purchased from, say, godaddy.com (as in my case)
For each of the domains that I bought, I use Godaddy's NS server and already in the Godaddy settings I create the records I need.
