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.
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.
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.
