The DNS is made up of numerous DNS zones. Moreover, the DNS server you’re using can better handle several zones to manage the DNS namespace. So, we can say that a DNS zone is a subset of the DNS namespace that a single administrator manages. It’s utilized as an organizational segment to provide you more control over DNS things like authoritative namespaces.
For your domain to function correctly, you must point it to various servers, including web servers, mail servers, etc. This is accomplished by adding multiple types of DNS records to the DNS zone. So, the DNS zone is where all Domain Name System records are stored. It is also the lone component responsible for the existence of the Domain Name System (DNS).
SOA record is an essential and one of the most common DNS records. It is crucial to understand it properly. So, let’s explain it!
The SOA record is the beginning of the chain of authority, which is typical for the DNS. The short SOA stands for start of authority. From all the nameservers that you have, the SOA record will show which holds the original zone file. This server will contain all of the essential data about the zone. It will be your authoritative DNS server.
