Title: Why are the third and fourth DNS records needed?

Why are the third and fourth DNS records needed?

A domain registrar has four areas to modify DNS records. But hosting providers ask you to enter only two. What are the other two for?

According to the rules of domain name registration, you need two different DNS servers (two records) with different IP addresses. The hosting provider must transfer the domain name + at least two DNS records to the registrar in order for the domain registration to be successful.
This rule about two records is provided in order to increase reliability - if the first one is unavailable, then the second one is accessed.
Often registrars allow you to register 2 records with the same IP addresses. This does not affect the operation of the domain in any way, however, in case of a potential failure or unavailability of the IP address of these two DNS servers, the domain will not work.

The third and fourth entries are provided for adding a third and fourth DNS server in order to increase stability and ensure the operation of the domain in case of failure of the first two servers.
