How to Change DNS Records (DNS – Domain Name System)?

DNS, also known as the Domain Name System, controls how your domain connects to services like your website, email, and third-party tools. Changing DNS records tells the internet where different parts of your domain should point.

Here’s a simple, step-by-step explanation of how to change DNS records:

Step 1: Log in to Your Domain Registrar
Sign in to the company where you purchased your domain name (this could be your hosting provider or a separate domain registrar).

Step 2: Find DNS Management:

• DNS Management
• Manage DNS
• DNS Settings
• Zone Editor

This is where all DNS records for your domain are stored.

Step 3: Edit or Add DNS Records:

Common DNS records you may need to change include:

• A Record – Points your domain to a web server’s IP address
• CNAME Record – Points one domain or subdomain to another domain
• MX Record – Controls where your email is delivered
• TXT Record – Used for verification, email security (SPF, DKIM), and services like Google or Microsoft

You can edit existing records or add new ones as needed.

Step 4: Save Changes

After making changes, save or apply them. DNS updates usually take a few minutes to several hours to start working, and in rare cases up to 24 – 48 hours to fully propagate worldwide.

Important Notes About DNS Changes:

• Small mistakes (like deleting the wrong record) can cause your website or email to stop working
• Always double-check values before saving
• Avoid changing DNS unless you know what the record controls
