Understanding DNS and How to Update Nameservers

The Domain Name System (DNS) is a crucial component of the internet that helps in directing traffic to the correct websites. For anyone who owns a domain or runs a website, understanding DNS and nameservers is essential. Whether you're changing hosting providers or just want to manage your DNS settings more effectively, knowing how to update nameservers is a valuable skill. In this guide, we’ll cover everything you need to know about DNS, its importance, and how to update your nameservers at BDIX NOC.

What is DNS?

DNS stands for Domain Name System, and it acts as a "phonebook" for the internet. When you type a domain name like www.example.com into your browser, DNS servers translate this human-readable address into an IP address that computers can understand and use to locate the website on the internet.

How Does DNS Work?

Here’s a basic overview of how DNS works:

1. User Request: When you enter a domain name in the browser (e.g., www.example.com), your computer sends a request to a DNS server.
2. DNS Lookup: The DNS server looks up the domain name in its records and retrieves the corresponding IP address.
3. Redirection: The IP address is sent back to your computer, allowing the browser to connect to the website's server and display the requested page.

What are Nameservers?

Nameservers are specialized servers responsible for managing DNS records for a domain. These records provide information about where to find the domain’s website, email servers, and other essential services. Essentially, nameservers point your domain to the correct host and ensure that your website loads correctly when accessed.

Every domain has at least two nameservers assigned to it, and they are often provided by your web hosting company or domain registrar. Nameservers are usually in the following format:

• ns1.example.com
• ns2.example.com

Why Do You Need to Update Nameservers?

You might need to update your nameservers in the following scenarios:

• When changing web hosting providers or moving to a new server.
• When configuring DNS records for specific services like email hosting or SSL certificates.
• If you're using BDIX NOC’s hosting services and need to point your domain to the correct servers.

Updating nameservers ensures that your domain is properly linked to the right services and that your website functions without issues.

How to Update Nameservers at BDIX NOC?

If you're using BDIX NOC for hosting, here's a simple guide on how to update nameservers for your domain:

Step 1: Login to Your Domain Registrar Account

Log in to the account where your domain is registered. This is often your domain registrar (e.g., bdixnoc, GoDaddy, Namecheap) or your hosting provider’s control panel.

Step 2: Navigate to Domain Settings

Once logged in, locate the section that allows you to manage your domain settings. This is usually under Domain Management, DNS Management, or Nameserver Settings.

Step 3: Find the Nameserver Management Section

Look for the option to edit nameservers. This section allows you to update the primary and secondary nameservers.

Step 4: Enter BDIX NOC Nameservers

Enter the nameservers provided by BDIX NOC. Typically, the nameservers for BDIX NOC are:

• dns1.bdixnoc.com
• dns2.bdixnoc.com

Make sure to save the changes once you've updated the nameservers.

Step 5: Wait for DNS Propagation

After updating the nameservers, it may take up to 24-48 hours for the changes to fully propagate across the internet. During this time, your website may experience some downtime, but once the propagation is complete, your website will be pointed to the new server.

Important Notes When Updating Nameservers

• DNS Propagation: As mentioned, DNS updates take time to propagate. During this period, users may experience inconsistency in accessing your site.
• Correct Nameservers: Always make sure you enter the correct nameservers provided by your hosting provider to avoid website downtime.
• Check DNS Settings: After the update, verify that your website is functioning properly. You can use online tools to check your DNS records.
