Creating a DNS server with a default response?

Question

linux

Hello, there are 50 domains and their number becomes larger and larger each time, and it is necessary to change the A-record on each of them in case of registering a new domain and direct it to a specific IP.
The task is as follows to prescribe the same NS domains (nameserver ns1 and ns2) and IP *.*.*.* was assigned to them by default.
What means can this be done? Using some self-made BIND configuration generator for all domains every time is not an option.
What are the options for solving such a problem? (Googled, but there is really nothing on this task there is a solution)

Answer 1

dnsmasq can do this:

Furthermore, it's possible to return a specific address for all domain names that are not answered from /etc/hosts or DHCP by using a special wildcard:
address=/#/1.2.3.4

Answer 2

Maybe it's easier to prescribe aliases (CNAME) for another domain name on all domains, and then if everyone needs to "move" - ​​will it be enough to change only one record?
