DNS Records: Definition, Functions, and Types

Monitoringclub.org – We may often hear about DNS records, if we play domains and hosting, they will never be released.

So, is DNS record important for hosting and domains? which we always use either to connect or verify domains with other services.

We will discuss more about DNS records in this article, please pay attention.

What are DNS records?

DNS Records or Domain DNS records are records that provide a mapping and an address internet domain name. This data consists of several types with different functions.

Or in plain language this DNS record contains an address and records regarding the server connected to the domain, of course we can also change and add the DNS record.

DNS Records function

After we get to know the next DNS record, we also need to know what are the functions of this DNS record. Why is it so important?

Among other things, DNS records have the following functions:

1. Providing Information About the hosting address.
2. Manage Domains Without Nameservers.
3. Added another DNS Function.

At point number 3 what we mean here is adding another type of record which we will thoroughly discuss in this article.

DNS Records Types

As I said above, DNS records have quite a lot of types. Therefore, we will discuss the types one by one, following the types of DNS records:

1. A record

A record it Contains IPv4. Serves to map a domain or subdomain to the IPv4 listed in it. IPv4 is a 32-bit IP address with the format aaa.bbb.ccc.ddd.

For example, if we want to map the Blogmarketingtool.com domain to the IP address 172.96.191.166, then we can fill in the A Record with the format: blogmarketingtool.com. 14400 in A 172.96.191.166 where the number 14400 is TTL (Time To Live, In seconds)

2. AAAA record

This AAA Record Contains IPv6. Serves to map a domain or subdomain to an IPv6 listed Inside. IPv6 is the newest IP format which consists of 128bit. This format is used because the number of IPv4 that can be mapped is still less than the number of computers connected to the internet with public IP.

3. CNAME Records

CNAME record Also known as an ALIAS or canonical name record creates an alias for a domain name. An aliased domain has all subdomains and DNS records like the original.

CNAME is often used to point multiple domains or subdomains to the same web hosting. eg To redirect www.blogmarketingtool.com to blogmarketingtool.com (without www) use CNAME with the format www.blogmarketingtool.com. 14400 IN CNAME blogmarketingtool.com.com

4. MX Records

The MX record contains information on the location of the mail server used by the domain, this will usually be filled in automatically when we connect the domain to a hosting service using Nameservers

5. PTR records

PTR record or also known as RDNS (reverse DNS). not listed in the DNS record on a named server.

PTR settings are custom made and can usually only be made by the server owner.

PTR Records are the opposite of A records. So it functions to direct IP to a domain or hostname. With PTR Records, we can find out who owns a particular IP.

PTR Records are very important in mail server settings. Email sent from a server that does not have a PTR record will be considered as SPAM.

6. NS records

NS records or name server records map a domain name to a list of DNS servers for that Domain. depending on the NS record, an example of an NS record is as follows ns1.hawkhost.com and Ns2.hawkhost.com

7. SOA Records

SOA record or start of authority record refers to a DNS server that provides authorization information about an Internet domain

For SOA, this record contains Domain Information that is being connected to the Server service.

8. SRV Records

The SRV record contains general information about Location Records

9. TXT Records

TXT Record allows administrators to enter random data into DNS records, this record is also used in the Sender Policy Framework specification. This txt record is usually used by developers to Verify their domain in the search console.

In addition, you can also read the DNS records recorded on a domain on https://dnschecker.org/

Then you enter the domain that you want to track record after clicking go then you will see the DNS record on the domain that was successfully tracked

Those are some explanations regarding DNS records that you can use to make settings for your domain.
