Understanding DNS record is easy. The only thing that you need a simple explanation. We will see what a DNS record is, and we will start speaking about one of the most used ones – DNS A record. It is the simple record that connects what you are typing in your web browser and the address of the site, but let’ go in-depth.
In the following page you can find in-depth information about the A record!
DNS and DNS records explained
We will not go into detail, but we should really define what DNS and DNS records are before we go to the topic of DNS A records.
The time before the Domain Name System
A long, long time ago, there was no Internet! Can you believe it? Back then, there were just a few university computers and some military ones linked together through different networks. They were working together, but with a lot of connection problems. The number of the devices started to grow, so did the connection between them.
Back then, each of the computers needed to have a hosts.txt file on their memory, which was basically a table with hosts’ names and their IP addresses. Like a table of A records, but of all possible devices that are there.
Imagine having to administrate a massive excel table with all the sites that you want to visit and their addresses. A lot of work!
The hosts.txt was not a viable option, so there was a need for a better system for that new thing called the World Wide Web. This is where the Domain Name System came.
Domain Name System explained
We just started to chat about DNS records with the DNS A Records, and now we will see a second DNS record – DNS MX record. MX does not mean Mexican. It means Mail Exchanger. We will go into details about why such a DNS record must exist and why can’t we freely send emails the way we want.

What is a DNS MX record?
Every action that relates to domains needs DNS records for instruction. In the DNS MX record case, it is a text document, mail exchanger record, that shows which server is responsible for receiving the emails that go for a particular domain.

DNS in short
DNS or domain name system is how the Internet is organized. Each host has its IP address and services that it uses. To access it and use those services, you will need to find it. The DNS is an international network of name servers that helps you navigate. It will translate your requests from words that you understand or commands on software to the language that the servers speak.
It is one communication level that we use without even knowing it!
DNS uses DNS records. Those are simple text messages with descriptions and instructions that servers understand. They link services, servers, and hosts. Thanks to those records, you don’t need to remember the IP addresses of sites you want to visit. You simply type the domain names in your browser, and you visit the site!
