How to Configure DNS for Your Website

Configuring DNS (Domain Name System) for your website is an essential step to ensure that your domain name points to the correct server and resolves to your website. When you configure your DNS settings, you're essentially telling the world where to find your website on the internet. Here's a step-by-step guide to help you configure DNS for your website hosted on BDIX NOC or any other hosting provider.

Step 1: Access Your Domain Registrar Account

To configure DNS for your website, you'll need to access the account where your domain name is registered. This could be with BDIX NOC, GoDaddy, Namecheap, or any other domain registrar. Once you're logged in:

1. Go to the Domain Management or DNS Settings section.
2. Select the domain name you want to configure.

Step 2: Find DNS Management Settings

Look for the DNS Management or Name Server Settings option in your domain registrar account. This section is where you can manage the DNS records for your domain.

• You may see options to manage A records, CNAME records, MX records, and TXT records. These are the most common types of DNS records you'll need to configure for your website.

Step 3: Update Name Servers (if necessary)

If you're hosting your website with BDIX NOC, you’ll need to point your domain to the BDIX NOC name servers. This will allow your domain to resolve correctly and direct visitors to your hosting server.

1. Find the Name Server Settings: In the DNS management section, look for options to set Name Servers (often labeled as “NS” or “Name Servers”).
2. Enter the Name Servers Provided by BDIX NOC: BDIX NOC typically provides you with the names of their DNS servers, such as:
   • ns1.bdixnoc.com
   • ns2.bdixnoc.com
3. Save the Changes: Once you enter the correct name servers, save the settings. DNS changes can take anywhere from a few minutes to 24-48 hours to fully propagate across the internet.

Step 4: Add or Modify DNS Records

After configuring your name servers, you can modify DNS records like A records, CNAME records, MX records, and TXT records. Here’s what each record type does:

1. A Record (Address Record): Points your domain to a specific IP address. This tells browsers where to find your website.
   • Example: If you're using BDIX NOC hosting, the A record will point to the IP address of your server.
   • Example Entry:
     • Host: @
     • Type: A
     • Value: 192.168.1.1 (your server's IP address)
2. CNAME Record (Canonical Name Record): Points a subdomain (e.g., www) to your domain name.
   • Example: If you want www.yourdomain.com to resolve to yourdomain.com, you’ll set a CNAME record.
   • Example Entry:
     • Host: www
     • Type: CNAME
     • Value: yourdomain.com
3. MX Record (Mail Exchange Record): Defines the mail servers for your domain, allowing you to send and receive emails.
   • Example: If you’re using a third-party email service, you’ll add their MX record details.
   • Example Entry:
     • Host: @
     • Type: MX
     • Value: mail.yourdomain.com
4. TXT Record: This is often used for verification purposes (e.g., for Google Search Console or email verification).
   • Example:
     • Host: @
     • Type: TXT
     • Value: "v=spf1 include:_spf.google.com ~all"

Step 5: Save Changes

Once you've updated or added the necessary DNS records, click Save Changes. Remember, DNS changes may take some time to propagate. It can take anywhere from a few minutes to a couple of hours for the changes to take effect globally.

Step 6: Verify Your DNS Configuration

After waiting for the DNS propagation, you can verify that your DNS records are working correctly. You can do this by using tools like:

• DNS Checker: A tool that shows the current DNS status for your domain.
• nslookup: A command-line tool that helps you check DNS records for your domain.
• WhatsMyDNS: A website that lets you check DNS propagation across multiple servers worldwide.

Common DNS Records You Should Know About

1. A Record: Points your domain to an IP address.
2. CNAME Record: Redirects a subdomain to a domain.
3. MX Record: Defines mail servers for email routing.
4. TXT Record: Used for verification and security purposes.
5. NS Record: Specifies the name servers for your domain.

Configuring DNS for your website ensures that your domain is correctly mapped to your server and can handle traffic, emails, and other services. By following these steps, you can configure your domain’s DNS settings and ensure your website is up and running smoothly. Don't forget that DNS changes may take some time to propagate fully, so be patient after making updates.
