Top 4 most popular DNS records

The Domain Name System (DNS) matches the domain names to their corresponding IP addresses. Thus, DNS records give the information for your hostname, domain, and IP address. With DNS records, you can adjust your domain configuration. There are many types of DNS records, but let’s start with the top 4 most popular of them.

A record and AAAA record

The A record is probably the most popular DNS record because it is used in almost any DNS system. It is an address record, so its purpose is to point a domain name to the corresponding IP address. Thanks to that, humans are not required to remember long and difficult numbers (IP addresses). Yet, the A record is usable when we are talking about IPv4 addresses.  

In case when we want to point a domain name to an IPv6 address, we have to use the AAAA record. It is not so commonly used in comparison to the A record. However, the amount of new devices is rapidly growing, so eventually,, the IPv6 and the AAAA record will also gain popularity.

ALIAS record vs CNAME record

Let’s compare these two DNS record types that have a similar purpose. Both redirect from one hostname to another, but they have more than a few differences in between. Let’s see what exactly distinguishes the ALIAS record and the CNAME record.

What is the ALIAS record?

ALIAS record links two hostnames, showing that one is just another way to write the other. It is not a standard DNS record type, and not all of the Managed DNS providers offer it. This record type can coexist with other DNS records, for example, MX records. A great thing about the ALIAS records is that they will save time and not only show the other hostname, but an ALIAS query will return the IP address. The only problem with ALIAS that might lead you to CNAME records is that it doesn’t work well with GeoDNS because it will show the IP address of the name server and won’t redirect to the best location.
