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.

DNS AAAA record explained

The DNS AAAA record is one of the essential Domain Name System records. It works with the IPv6 address. Let’s explain a little bit more about it.

What is the DNS AAAA record?

The DNS AAAA record is a DNS resource record. It has the main purpose of linking a domain name with the IP address, which it corresponds to. This is a process that happens every time a domain name is requested for the site to be accessible. The browser will be incapable of finding the IP addresses successfully for the requested domain names. For users will be impossible to reach your website without help from the AAAA record.

DNS CAA record meaning

The DNS records are the instructions that clients and servers are searching for a particular domain. The common ones are the A records for a domain name to IP address resolution, the CNAME for redirecting subdomain to the domain name, MX for incoming mail servers, etc. But the DNS CAA record is not so well-known, so now we will explain it to you.

What is a DNS CAA record?

The DNS CAA record (Certification Authority Authorization) is a record that the DNS administrator of a domain can add to clarify which Certificate Authorities (CAs) can issue SSL or TLS certificates for the particular domain. The CA are external organizations that you, as a domain owner, can choose to issue cryptographic certificates like SSL or TLS for your domain name.

The cryptographic certificate is used to validate the domain owner and to encrypt the communication with that domain. That way, it protects sensitive data.

With the CAA, the domain owner will have improved control over the process of issuing certificates. He or she can clearly state who is permitted to issue certificates and lower the number of miss-issued certificated for that domain. The CAA record can be used for the whole domain, or chosen subdomains only, depending on how you set it up.

One common requirement for using CAA records is to first enable DNSSEC. That is required for better security and trust from the side of the CA.
