Where can I get NS for my own DNS server?

Question

css

Hello!
I want to register a domain for example.com .
For a successful configuration, the DNS registrar asks to register NS records for delegation.
I want to make ns1.example.com for NS1, ns2.example.com for NS2.
But here comes the problem. If I write ns1.example.com then the address will not be resolved.
How to tell the registrar which IP is for ns1.example.com and ns2.example.com ?
Only domains can be entered in the NS registration field.
ps If the DNS provider on the site does not provide for the possibility of A records for NS1\NS2, then you need to write to the support service?

Answer 1

Why not use tables? colspan for td lets you concatenate cells, while rowspan lets you concatenate rows. those. instead of two columns, to display one large (two columns), write
<td colspan="2">Я широкая колонка!</td>

Answer 2

Why don't you like your registrar's NS?
They will probably have higher reliability than your own.
Again, you can place Secondary at the registrar, and put Master at your place and not register it in NS.

Answer 3

You can simply enter an IP address or an address like blablabla.no-ip.org of your dns server (if you have it dynamic).

Answer 4

For full DNS work, you need a minimum of IP addresses (better and servers) in different subnets
, you can use the same server, but you won’t get away from 2 different IPs
