What is DNS Records Management?

Think of the Domain Name System (DNS) as the internet’s phonebook or GPS navigation system.

While humans remember website names like yourdomain.com , servers communicate using numerical IP addresses like 192.198.16.25 DNS Records Management is the process of setting up simple routing rules that direct your domain name to the correct servers for your website, emails, and online services.

Common DNS Record Types Explained

  • A Record (Address Record)

The A Record maps a domain or subdomain directly to an IPv4 address. Its primary function is to direct visitors to your web server's location. For example, it points yourdomain.com  to an IP address like 192.198.16.25

  • AAAA Record (IPv6 Address Record)

The AAAA Record maps a domain or subdomain to an IPv6 address instead of an IPv4 address. It functions similarly to an A Record by routing site traffic using the modern IPv6 network protocol, such as pointing yourdomain.com to 2001:db8::1

  • CNAME Record (Canonical Name)

The CNAME Record aliases one domain or subdomain to another domain name rather than an IP address. It is commonly used to link subdomains to your primary domain or external services, such as pointing blog.yourdomain.com to yourdomain.com 

  • MX Record (Mail Exchanger)

The MX Record routes all incoming email traffic for your domain to your designated mail server. It ensures that emails sent to your custom address reach your mailbox, whether you use cPanel email hosting, Google Workspace, or Microsoft 365.

  • TXT Record (Text Record)

The TXT Record stores plain-text information and security keys attached to your domain. It is primarily used to verify domain ownership for external tools and to configure email security protocols such as SPF, DKIM, and DMARC to prevent email spoofing.

  • NS Record (Name Server)

The NS Record specifies the authoritative name servers responsible for managing your domain's DNS configuration. For example, setting your NS records to ns2.srilankahosting.lk and ns2.srilankahosting.lk delegates all DNS record control to SriLanka Hosting.

When Do You Need to Manage DNS Records?

You will typically edit or add DNS records when you need to:

  1. Connect a Website: Point your domain to a website builder or host (e.g., WordPress, Shopify, Wix, or SriLanka Hosting).

  2. Setup Business Emails: Link custom email addresses to providers like Google Workspace or Microsoft 365.

  3. Verify Domain Ownership: Confirm domain ownership for tools like Google Search Console or SSL security validation.

Good to Know (DNS Propagation):

Whenever you create or update a DNS record, it takes time for internet service providers (ISPs) around the world to update their systems. This process is called DNS Propagation and typically takes 1 to 24 hours (though it can take up to 24 hours in rare cases).
