List of the basic DNS record types

DNS record types

Dо you want to learn more about the different records? If yes, you are in the right place. Here you can find the list of the most popular DNS record types.

1. SOA record

The Start Of Authority record, or SOA record for short, is the first on our list. It is the one that must be comprehended. Why? It represents the beginning of the Authoritative DNS zone. This DNS record contains a wealth of data for the DNS zone. If you want your network to run smoothly and without errors, you’ll need this DNS record. It sends all requests to the principal DNS server. In addition, the SOA record contains the information and contact information for the DNS administrator. A variety of parameters, such as the domain serial number, are also included. It’s worth noting that each DNS zone should have just one SOA record.

CNAME record explained

CNAME record

The CNAME record is one of the first DNS records that you will read about when you are starting with DNS management. It has a very important task to do, showing the true domain name for the subdomains, making it really an essential DNS record. It saves time and makes it easier to manage the DNS.

CNAME explained completely

There are two parts in the CNAME’s name. C stands for canonical, and it wants to show which is the true domain name for the one that you are trying to resolve. The NAME is obvious. It stands for name, as in hostname.

DNS propagation explained

DNS propagation

Imagine this situation. You have finally decided to truly manage your DNS. You have selected a DNS service provider, you have created master and secondary zones, and you have added all the DNS records that you will need. You spend a lot of time and effort. And after everything is ready, you want to check and… there are no changes! Don’t worry. The DNS propagation takes time.

What is DNS propagation? 

It is a process to update the changes that you make in your DNS. After editing or creating new DNS records, they are saved in the authoritative DNS nameserver. That is ok, but what about all the rest of the DNS name servers? The cache memory of the recursive DNS servers will still keep the older versions of the DNS records based on their TTL value.
The DNS propagation is the time it will take to propagate, to update the changes to all of the recursive name servers.

Frequently asked questions about DNS propagation

Do you have any doubts about the DNS propagation, we hope you can find your answer here:

Could we make the DNS propagation faster?

Of course, we can, but there is a catch. Boosting the speed depends on the TTL value of the DNS records, so lowering the TTL value of each of the DNS records will indeed guarantee faster DNS propagation. The problem is that you might not want to have DNS records with low value. It will stress more your DNS servers, updating them too often.
We don’t need all of our DNS records to update all the time.
It is better to keep the records’ TTL values at their normal level. Plus, editing all of them will take a lot of time.

Can you check if the DNS propagation is ready?

Of course, we can, and this time there is no problem. You need to see if the IP address for a domain name has changed. This will indicate that the A or AAAA records are updated already.
We will show you different ways depending on your OS.

*Change yourdomainname.com with your actual domain name.

Linux or macOS

Open the Terminal, and we will use one of the built-in commands called the Dig command.

dig yourdomainname.com

You can use the host command too, whatever you prefer.

Windows OS
The Terminal alternative in Windows is the Command Prompt. Inside it, we will use the NSlookup command.

nslookup yourdomainname.com

How long can the DNS propagation take?

It can take a long time. Depending on when the recursive DNS servers updated themselves and the TTL values of the DNS records, it can take as much as 72 hours.

Conclusion

Waiting for the DNS propagation to occur is a time-consuming process that we could not fully predict. This is the situation, and there is little we can do, so just be patient, and in less than 72 hours, the update will happen.
Patience is the key here!
