To properly understand DNS and its function, we must investigate each of the DNS records, how they work, and why they exist. There are many, but there are a few that we must understand from the start. This is why we will begin by explaining the DNS SOA record.
What is DNS SOA record?
The DNS SOA record is the start of authority. It is the beginning of the chain of authority that the DNS has. It will point which server, from all the nameservers that you have, contains the original zone file. This server will be the authoritative DNS server, and it will have all the important information about the zone.
Inside the DNS SOA record, there you can find information about the zone transfer, the rate of refreshing, and the rate for retry if not refreshed properly. Also, inside it, you will see the DNS administrator’s contact information.
Here you can find the structure of the DNS SOA record!

The domain name system (DNS) always has something in store for us to learn. From its architecture to its functionality, different components, and records. And exactly today, it is the turn of DNS MX recorded to be explained.
What is the DNS MX record?
MX stands for mail eXchange record. DNS records are vital for giving instructions for different DNS processes to happen. A DNS mail exchange record (MX) is a resource record that the domain name system uses to point correctly to the exact name of the incoming e-mail server where e-mails have to be sent. Yes, you got it! MX record indicates the responsible server that has to get the e-mails sent to a determined domain.

Expanding the knowledge about DNS records, we can’t skip another of the essential DNS CNAME record.
DNS CNAME record explained
The full name of the CNAME record is Canonical name record. The Canonical Name is demonstrating which exactly is the real name of a domain. In that direction of thought, the DNS CNAME record serves the purpose to point which is the true canonical domain name of one domain name.
Find out the most common uses of the CNAME record!

Whatever we do, there will be failures. The computer can break down; the connection can get saturated; a bug can cripple a server, or whatever other reason can lead to a big problem. But can a person stay 24-hour a day monitoring our DNS servers? There is a better solution, a service that will monitor your DNS traffic and act if there is a problem, and it is called DNS Failover.
