When you type a domain name into your browser\u2019s address bar and hit Enter, you activate a special communication system known as the domain name system (DNS). This system translates your text into an IP address, which is a special code your browser uses to connect to the site you\u2019re looking for. To make that happen, machines and DNS servers have to locate a file, known as a DNS record, that holds the details on how to handle the website you requested.<\/p>\n\n\n\n

DNS records store different kinds of information, depending on their type, and each type serves a specific purpose.<\/strong> In this guide, we\u2019ll explain what DNS records are, the most common record types, and why they\u2019re a crucial part of the internet\u2019s infrastructure.<\/p>\n\n\n\n

What Are DNS Records?<\/h2>\n\n\n\n

A domain name system record, usually just called a DNS record<\/strong>, is a file that contains information and instructions needed to link domain names to numerical IP addresses stored in DNS servers<\/strong>. It tells browsers what you\u2019re looking for and holds the key details that make communication possible between you and the web servers behind the scenes. If you have a website, you need a DNS record to keep it running smoothly.<\/p>\n\n\n\n

A good way to understand the DNS system is to think of it like your smartphone\u2019s contacts app. Every time you want to call a friend \u2013 the domain address in this analogy \u2013 you don\u2019t type in their phone number, which would be the IP address. Instead, you just type their name, and your contacts app \u2013 the DNS system \u2013 pulls up their contact card with their number and maybe even their email. That contact card is basically a DNS record.<\/p>\n\n\n\n

Each DNS record is a text-based file that follows a specific DNS syntax structure<\/strong>, called a zone file<\/a>, and responds to DNS queries. When all this information is organized correctly, it lets computer systems communicate and load the website you want to visit. However, even though all DNS records follow the same general framework, they don\u2019t all look alike, and they don\u2019t all work the same way.<\/p>\n\n\n\n

How DNS Records Work<\/h2>\n\n\n
\n
\"\"<\/figure>\n<\/div>\n\n\n

The way DNS systems access DNS records is a bit complicated, but in simple terms, a DNS system escalates requests until they reach the correct DNS record to give you an answer.<\/strong><\/p>\n\n\n\n

So, whenever you type the name of the domain you want to visit, you generate a request. Then, your computer starts asking different DNS servers \u2013 following a specific hierarchy \u2013 until it finds the DNS record that contains the information for that web address. Once it finds the right record, your browser uses the instructions in that file to route your browser request to the IP address of the URL you typed.<\/p>\n\n\n\n

A Closer Look At The Process<\/h3>\n\n\n\n

The first place your browser looks when you enter a domain name is its own DNS cache. If you\u2019ve visited the site before and it still has that information stored, it\u2019ll take you there immediately. If not, it checks your operating system\u2019s cache. If it\u2019s not there, either, your browser turns to a recursive resolver, like Google\u2019s public DNS service<\/a> by \u201ccalling\u201d its popular IP address: 8.8.8.8.<\/p>\n\n\n\n

If Google\u2019s server \u2013 or any other recursive resolver \u2013 doesn\u2019t have the answer, your browser has to ask other servers, in a specific order, until one provides the information required: root name servers, then TLD servers, and finally authoritative name servers.<\/p>\n\n\n\n

The Most Common DNS Record Types<\/h2>\n\n\n
\n
\"mind<\/figure>\n<\/div>\n\n\n

There are many different kinds of DNS records. Some are rarely used, while others are used on a daily basis. Here are the most common types of DNS records and their applications:<\/p>\n\n\n\n

1. A Record: IPv4 Address Record<\/h3>\n\n\n\n

An Address Record, most often known as just an A record, is used to connect domains to IPv4 addresses<\/strong>. It\u2019s the most common DNS record<\/strong><\/a> because IPv4 is still the most widely used IP protocol in the world. The file itself is simple and straightforward, and many other DNS records depend on A records to work.<\/p>\n\n\n\n

It was introduced in 1987<\/a>, and it remains a crucial part of the internet structure, as most active domains have an A record. A simple A record can look like this:<\/p>\n\n\n\n

Domain\u00a0<\/strong><\/td>Record type\u00a0<\/strong><\/td>IPv4<\/strong><\/td><\/tr>
example.org<\/td>A<\/td>198.51.100.0<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

2. AAAA Record: IPv6 Address Record<\/h3>\n\n\n\n

An AAAA record, also called a \u201cquad A record,\u201d works almost the same way as an A record, but instead of an IPv4 address, it links domains to IPv6 addresses<\/strong>. When A records were first created, IPv6 addresses didn\u2019t exist yet, so this type of DNS record was introduced later.\u00a0<\/p>\n\n\n\n

A quad A record stores IPv6 addresses<\/a> associated with a domain, along with a time-to-live (TTL) value in seconds \u2013 which is the time estimated for a server to refresh the DNS record information. TTLs are also included in other DNS record types.\u00a0<\/p>\n\n\n\n

Domain\u00a0<\/strong><\/td>TTL<\/strong><\/td>Record type\u00a0<\/strong><\/td>IPv6<\/strong><\/td><\/tr>
example.org<\/td>600\u00a0<\/td>AAAA<\/td>2001:db8:abcd:1234::5<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

3. CNAME Record: Canonical Name<\/h3>\n\n\n\n

A Canonical Name record, popularly known as CNAME record, is used to link A records and quad A records to subdomains. CNAME records are frequently used to redirect addresses<\/strong>, like \u201cwww.example.org\u201d and \u201cexample.org,\u201d to the same website.<\/p>\n\n\n\n

Using CNAME records makes it easier to manage and update your site, since you can point multiple subdomains to one main record. A basic CNAME setup looks like this:<\/p>\n\n\n\n

Subdomain\u00a0<\/strong><\/td>TTL<\/strong><\/td>Record type\u00a0<\/strong><\/td>Domain (target)<\/strong><\/td><\/tr>
www.example.org<\/td>3600\u00a0<\/td>CNAME<\/td>example.org<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

4. MX Records: Mail Exchangers<\/h3>\n\n\n\n

A mail exchanger record, or MX record, connects email addresses to a domain\u2019s mail server. <\/strong>MX records are crucial for email services. Every time you send an email, an MX record is consulted to determine which mail server is supposed to receive it.\u00a0<\/p>\n\n\n\n

It can look like this, including a priority or preference value<\/a> that acts as a delivery order for the server:\u00a0<\/p>\n\n\n\n

Subdomain\u00a0<\/strong><\/td>Record type\u00a0<\/strong><\/td>Priority<\/strong><\/td>Domain (mail server)<\/strong><\/td>TTL<\/strong><\/td><\/tr>
www.example.org<\/td>MX<\/td>10<\/td>mail.example.org<\/td>3600<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

5. TXT Records: Text Records<\/h3>\n\n\n\n

Text records, descriptive texts, or TXT records, arefiles that store extra information about subdomains and domains.<\/strong> This type of DNS record also acts as an official source to help receiving servers verify data and filter out spam<\/a>.\u00a0<\/p>\n\n\n\n

A text record can contain different kinds of useful notes, such as email authority information or domain verification:<\/p>\n\n\n\n

Subdomain\u00a0<\/strong><\/td>Record type\u00a0<\/strong><\/td>TTL\u00a0<\/strong><\/td>Text<\/strong><\/td><\/tr>
example.org<\/td>TXT<\/td>3600<\/td>v=spf1 ip4:192.0.2.10 ip4:203.0.113.25 -all<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

6. NS Records: Name Server<\/h3>\n\n\n\n

A name server, or NS record, is another type of DNS record thattells your browser which DNS servers are officially responsible for your domain<\/strong>. It delegates authority and points your browser to the best source for answering any queries related to your domain.<\/p>\n\n\n\n

Subdomain\u00a0<\/strong><\/td>Record type\u00a0<\/strong><\/td>TTL\u00a0<\/strong><\/td>Server<\/strong><\/td><\/tr>
example.org<\/td>NS<\/td>3600<\/td>ns1.exampledns.com<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

7. PTR Record: Pointer Record<\/h3>\n\n\n\n

A pointer record, also known as a PTR record, does a similar job to the A and AAAA records, but in the opposite direction. This type of DNS record says which IP address is connected to your domain<\/strong>, and this information can only be created or changed by the organisation that controls the IP address. PTR records are used for reverse DNS lookups, a common practice for verifying authenticity and spotting potential spam.<\/p>\n\n\n\n

IP Address<\/strong><\/td>Record type\u00a0<\/strong><\/td>TTL\u00a0<\/strong><\/td>Hostname<\/strong><\/td><\/tr>
203.0.113.45<\/td>PTR<\/td>3600<\/td>server.example.org<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

8. SOA record: Start of Authority<\/h3>\n\n\n\n

A start of authority, or SOA record, contains essential administrative information about your domain\u2019s management<\/strong>. It identifies the primary name server for the domain and provides contact information for the DNS administrator, as well as rules for how other DNS servers should handle updates and refresh the settings.<\/p>\n\n\n\n

Subdomain\u00a0<\/strong><\/td>TTL\u00a0<\/strong><\/td>Record type\u00a0<\/strong><\/td>Server<\/strong><\/td><\/tr>
example.org<\/td>3600<\/td>SOA<\/td>ns1.example.org. admin.example.org. (2025010101 ; Serial 3600; Refresh (1 hour) 600; Retry (10 minutes) 1209600; Expire (14 days) 3600; Minimum TTL (1 hour))<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Other types of DNS Records<\/h2>\n\n\n\n

There\u2019s no official number for how many types of DNS records are active out there<\/strong> in the wild web, just dozens that have been identified, categorized, and that are frequently used. These files have been designed to evolve. However, after a certain time, and with the development of new technologies, some of them become obsolete<\/strong>.\u00a0<\/p>\n\n\n\n

Along with the most common DNS record types mentioned, there are other types that you might encounter when you\u2019re managing your website or researching more on DNS systems. Some of them have very specific purposes.<\/strong> For example, an SRV record, which is used by applications to find endpoints, or a CAA record, which hosts information on certificate authorities that are allowed to issue certificates for your domain, and is checked when you issue an SSL certificate.\u00a0<\/p>\n\n\n\n

How to Find DNS Records<\/h2>\n\n\n\n

There are several methods and tools you can use to look up DNS records.<\/strong> For example, on Windows, you can use the nslookup utility or Resolve-DNSName command to learn about DNS records associated with a domain.\u00a0\u00a0<\/p>\n\n\n\n

Through an nslookup command, you can find multiple types of DNS records, including CNAME, A, AAAA, MX, TXT, and SOA records. You can also identify which server hosts these DNS records.\u00a0<\/p>\n\n\n\n

Another popular DNS tool is the DIG command, which is usually installed on Macs and Linux systems. DIG can find A records for the URLs you type in to the interface.

You can also use online tools such as \u200b\u200bDNSChecker.org<\/a> or nslookup.io<\/a>, which offer user-friendly platforms where you can type the domain name and search for available DNS records.<\/p>\n\n\n\n

Finally, if you have access to the control panel for your domain and hosting service, you can also see, edit, and manage DNS records directly.\u00a0<\/p>\n\n\n\n

How to Manage DNS Records<\/h2>\n\n\n\n

To manage DNS records, you need access to the DNS provider tools and servers that control them. The most common way to do this is through your domain registrar or hosting provider. Once you\u2019re logged in, look for the DNS settings. From there, you can add, delete, or edit DNS records and save your changes.\u00a0<\/p>\n\n\n\n

You can also use tools such as Windows PowerShell if you are working with a Windows DNS server. And, depending on the DNS provider, it could take either just a few minutes or hours for the changes to synchronize online.\u00a0<\/p>\n\n\n\n

FAQ<\/h2>\n\n\n\n

What are the different types of DNS records?<\/strong><\/h3>

There are many types of DNS records<\/a>, each serving a different purpose. Some DNS records, such as A and AAAA records, connect domain names to IP addresses. MX records are crucial for email routing. Other DNS records, such as NS and TXT records, are used to verify data and authenticity.\u00a0 A few more have specific functions and roles in the internet infrastructure and security.

<\/p> <\/div>

How do DNS record types work?<\/strong><\/h3>

DNS records are files that store important information about domains<\/a>. Every time you type a URL in your browser, your device asks DNS servers for information about the site\u2019s location and ownership. The different types of DNS records store the most important information and instructions about a given site, such as its IP address. Together, they provide all the right data that allows you to browse the site.

<\/p> <\/div>

What are the most common DNS record types?<\/strong><\/h3>

The most common DNS record types<\/a> are A, AAAA, CNAME, MX, TXT, NS, PTR, and SOA. These types of records are used on a daily basis every time you visit a website, send an email, or verify a domain ownership.

<\/p> <\/div>

How are DNS record types used to manage domains?<\/strong><\/h3>

Domain owners, website administrators, and hosting providers use DNS records to update, add, modify, or remove information about a domain. To do this, the person who wants to adjust the DNS file information must have access to the domain\u2019s DNS management dashboard<\/a>, hosting service control panel, or specialized DNS management tools.

<\/p> <\/div>

Can VPNs affect how DNS records are resolved?<\/strong><\/h3>

Yes, VPNs can change the way your browser accesses a domain\u2019s DNS records to offer results. When you use a VPN to access a website, it may send DNS requests to its own resolver. Other VPN features, such as PIA\u2019s Smart DNS service, can also change the way your device accesses different DNS services.<\/p> <\/div> <\/div>\n\n\n\n\n","protected":false},"excerpt":{"rendered":"
