DNS Records: A Step-by-Step Guide For Beginners

Using the Internet without DNS would differ from what it is now. We would have to memorize their IP addresses to access websites, which does not seem to be a pleasant user experience. And the DNS is the Internet’s telephone book that connects web browsers with websites. Furthermore, all DNS records are critical to the operation of this system.

The domain name system (DNS) is one of the most popular internet services, yet it is also vulnerable to attacks based on DNS. It is essential to understand DNS and its functionality to prevent DNS attacks.

It is important to note that DNS servers contain one crucial component: the DNS zone file. Each of these records contains specific instructions for other servers to follow to connect to the various services on the domain, such as a web server for viewing a website or a mail server for receiving emails.

Many “standard” DNS record types, such as the A record, CNAME, MX, and TXT records, are familiar to domain owners and users. These records have an important impact on the actions of online users daily. Many DNS record types are available in addition to those that are more commonly used.

Many internet users are unaware of it. Let us review the DNS record; all DNS records types.

What is DNS Record?

DNS (Domain Name System) serves as the telephone book of the Internet. Domain names example.com enable humans to access information online. IP addresses are how web browsers communicate with one another over the Internet. DNS allows browsers to load Internet resources by translating domain names into IP addresses.

 

Each device must have a unique IP address for other devices to locate a device connected to the Internet. By using DNS servers, humans don’t need to memorize IP addresses such as 192.168.1.1 (in IPv4) or more complex IP addresses such as 2400:cb00:2048:1::c629:d7a2 (in IPv6).

Moreover, In DNS resolution, the hostname (such as www.example.com) is converted into a computer-friendly IP address (such as 192.168.1.1). Every Internet device has an IP address, which is used to locate that device on the Internet in the same way a street address is used to locate a particular residence. 

The web browser must translate what the user types into the address bar (example.com) into the machine-friendly address required to locate the example.com website.

It is important to note that this convergence system is based on all its DNS records. To understand those records read this article thoroughly. 

Most Common DNS Record Types

There are over 90 types of DNS records, but you do not have to be familiar with them. It is important to note that many resource records are no longer used. We have compiled a list of the most common DNS records you will likely encounter. And you can perform the DNS lookup for any domain for its all DNS records  iplocation.io/all-dns-records-of-domain.

  • A record

    • A record is one of the simplest and most fundamental types of DNS records. A stands for “address,” and whenever you want to view a website, send an email or do anything else on the Internet, the domain you enter must be associated with an IP address. An A record indicates the IP address of a domain.
  • Example of A record
Domain TTL (time to live) Record type Value
ipxo.com 300 A 172.67.183.148
  • AAAA record

    • As A records are to IPv4 addresses, AAAA records are to IPv6 addresses. Domain names are associated with IPv6 addresses in these records. The IPv6 address is longer than the IPv4 address, which is another important difference between the two.
  • Example of AAAA record
Domain TTL (time to live) Record type Value
ipxo.com 300 AAAA 2606:4700:3032::ac43:b794
  • CNAME record

    • When a subdomain or a domain is an alias for another domain, this record replaces the A record. A CNAME record must always refer to a domain as it does not contain an IP address.
  • Example of CNAME record
Domain TTL (time to live) Record type Value
example.com 32600The CNAME record (or the “canonical name” record) maps an alias to a canonical domain name. CNAME example.com
  • MX Record

    • The DNS MX, or mail exchange record, is responsible for directing emails to the appropriate mail server. Like CNAME records, the MX record specifies how an email message should be handled, and it is always required to point to another domain. 
  • Example of MX record
Domain TTL (time to live) Record type Preference Value
ipxo.com 3600 MX 0 ipxo-com.mail.protection.outlook.com
  • TXT Record

  • In DNS; TXT records are text records that allow domain administrators to add text to the DNS. TXT records were initially intended to enter human-readable notes, but now it is possible to input machine-readable data into them.
  • Example of TXT record
Domain TTL (time to live) Record type Value
ipxo.com 300 TXT MS=ms30920366

Bottom Line

In the end, we can say that the DNS is the server that holds all the domain’s IP addresses. Moreover, this system works with its all DNS records.
